Deep condensate gas reservoirs exhibit highly complex and variable phase behaviors,making it crucial to understand the relationship between fluid phase states and flow patterns.This study conducts a comprehensive analysis of the actual production process of the deep condensate gas well A1 in a certain oilfield in China.Combining phase behavior analysis and CMG software simulations,the study systematically investigates phase transitions,viscosity,and density changes in the gas and liquid phases under different pressure conditions,with a reservoir temperature of 165°C.The research covers three crucial depletion stages of the reservoir:single-phase flow,two-phase transition,and two-phase flow.The findings indicate that retrograde condensation occurs when the pressure falls below the dew point pressure,reachingmaximum condensate liquid production at around 25MPa.As pressure decreases,gas phase density and viscosity gradually decrease,while liquid phase density and viscosity show an increasing trend.In the initial single-phase flow stage,maintaining a consistent gas-oil ratio is observed when both bottom-hole and reservoir pressures are higher than the dew point pressure.However,a sudden drop in bottom-hole pressure below the dew point triggers the production of condensate oil,significantly reducing subsequent gas and oil production.In the transitional two-phase flow stage,as the bottom-hole pressure further decreases,the reservoir exhibits a complex flow regime with coexisting areas of gas and liquid.In the subsequent two-phase flow stage,when both bottom-hole and reservoir pressures are below the dew point pressure,a significant increase in the gas-oil ratio is observed.The reservoir manifests a two-phase flow regime,devoid of single-phase gas flow areas.For lowpressure conditions in deep condensate gas reservoirs,considerations include gas injection,gas lift,and cyclic gas injection and production in surrounding wells.Additionally,techniques such as hot nitrogen or CO_(2) injection can be employed to mitigate retrograde condensation damage.The implications of this study are crucial for developing targeted development strategies and enhancing the overall development of deep condensate gas reservoirs. 展开更多

The continuous debate on the formal rule of law and the substantive rule of law in the construction of the rule of law in China not only affects the understanding of the connotation of the rule of law in China,but also the choice of the path for the development of the rule of law in China.In the new stage of “comprehensively advancing the Law-Based Governance of China”,the process of “comprehensively advancing the Law-Based Governance of China” is also a process of continuously improving the rule of law quality in China.And from this perspective,the relationship between the formal rule of law and the substantive rule of law has got a new meaning.Promoting the substantive rule of law is an important way to realize the development of the rule of law and improve the quality of the rule of law.At the same time,the promotion of the substantive rule of law should follow the “people-centered” nature of the rule of law and the objective is conducive to the promotion of the rule of law and the formation of the “rule of law ecology”. 展开更多

According to the macromarket law, the total supply will go to equilibrium with the total demand for the world as a whole. Textiles are consumables, the total demand of which must be proportional to the population. For any large district, the share ratio - the ratio of the local productivity world share to the local population world share,will approach unity in long term period. The uncommon prosperity of the textile industry in the developed countries before the Second World War had been established by super economical means of the old era. The developing countries nowadays have no such means, and will never be able to establish the local textile Industry to an uncommon large scale. The development model of the textile industry must be in four stages: the first two are common both for the developed and for the developing countries, namely demand leading - supply leading. The third stage is quite different: uncommon expansion followed by significant declination, for the developed, and the re - 展开更多

Chips are the carriers of ICs (integrated circuits). As a result of design, manufacturing, and packaging and testing processes, chips are typically wholly independent entities intended for immediate use. According to known data, one unit of chip output can drive up to ten units of output in the electronic information industry and 100 units of GDP (Gross Domestic Product). The Chip Information Industry is a strategic industry in most developed countries in Europe and North America. The development of the Chip Information Industry is related to national economies and personal livelihoods. Moore discovered a certain trend after analyzing data: in general, every newly produced chip has twice the capacity of the previous generation, and it takes 18 to 24 months for the next generation to be subsequently invented. This trend has come to be known as Moore’s Law. It applies not only to the development of memory chips but also to the evolutionary paths of processor capability and disk drive storage capacity. Moore’s Law has become the basis of performance prediction in several industries. However, since 2011, the size of silicon transistors has been approaching its physical limit at the atomic level. Due to the nature of silicon, additional breakthroughs in the running speed and performance of silicon transistors are severely limited. Elevated temperature and leakage are the two main sources that invalidate Moore’s Law. To counter these issues, This paper analyzes specific problems challenges in the Chip Information Industry, including the development of carbon nanotube chips and fierce competition in the international Chip Information Industry. In addition, this paper undertakes a critical analysis of the Chinese Chip Information Industry and countermeasures to Chinese Chip Information Industry development. 展开更多

Discussions on grasping the laws and trends of historical development take a fundamental theoretical position in the scientific system of Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era.Xi Jinping’s important statements have systematically answered such questions as what type of laws and trends of historical development should be followed,how did the Party follow the laws and trends of historical development in its centennial history,and how should the laws and trends of historical development be followed in a new era.The birth of the Communist Party of China(CPC),the victory of China’s War of Resistance against Japanese Aggression,the founding of the People’s Republic of China,and the unveiling of a new era for reform and opening up and socialism with Chinese characteristics are all the results of grasping the laws and trends of historical development.Over the past century,the Party has followed the laws and trends of historical development and continuously advanced the sinicization of Marxism on the basis of adhering to the unification between truth and values.In pursuit of“putting people first,”the Party has courageously been reforming itself and made relentless progress in the great endeavor of Party building.History shows that a keen appreciation of the laws and trends of historical development is an important sign of political maturity for a proletarian party.Only by applying Marxism according to current times and conditions will we keep abreast with the laws and trends of historical development.We should establish a broader concept of history and identify the laws and trends of historical development from the interactions and linkages between China and the rest of the world.We must recognize and promote the outstanding role of great leaders in steering the country in line with the laws and trends of historical development. 展开更多

Nigerian literatures contain history in the oral tradition and folklore like satire, proverbs, chants, symbolism etc. in the pre-literate period, Nigeria enjoyed high level of verbal art civilization which traditional rulers and the generality of the populace patronized. The oral tradition served as medium of preservation of culture and history of the ancient past and experiences. Though, most Nigerians can still remember their family history, folklore, tradition and genealogy, only few oral artists and youths of nowadays possess the skill and ability needed to chant the lengthy oral literature. It is in the light of the above that this study examined the effect of oral tradition, folklore, and history on the development of education in Nigeria, 1977 till date. The study adopted historical research method using primary and secondary sources of information to analyze data. Primary sources include, like archive materials, oral interviews and secondary sources include, like textbooks, speeches, journals, and internet materials and images. The outlines of the paper are: the definition of concepts, historical background of Nigerian oral tradition, and folklore in the educational system, the place of oral tradition, folklore and history in the education policy in Nigeria since 1977, the effect of oral tradition, folklore and history on the development of education in Nigeria since 1977, the prospects of oral traditions, folklore and history on the development of education in Nigeria, conclusion and a few recommendations for future improvement. The findings of the study revealed that oral traditions, folklore and history were the bed-rock for the development of education and society in the pre-colonial period, but these were dropped gradually with the advent of the colonial masters and gradually deteriorate both in the educational curriculum and general conduct of the society and these have adverse effect on the nation's economy. It is recommended that the beauty of Nigerian history, oral and written traditions, culture, folklore like proverbs, chants, satire and symbolism, be brought back into the school system, politics and every sector of the Nigerian economy for proper advancement to take place in the education sector and for overall national development. 展开更多

Since the amalgamation of the Northern and Southern Protectorates of Nigeria by Sir Lord Lugard, a former Colonial Master, in 1914, the country has not remain the same, because of historical/cultural differences of both Protectorates, that tends to affect the unity and leadership style of the country. This is because both sides of the country see themselves as strange bed fellows, as regards governance style and approach to issues of development, in most occasions. Various crisis across time in the country, can also be traced to the historical and cultural differences, amongst others, that exist between both sides of the country. To a large extent, affect the utilization of resources for development in the country by the various leaders that occupy positions of leadership. The main source of data for this study was through the Desk Study (DS) method, coupled with the Focus Group Discussion (FGD). Interview of this, this paper critically looked at the effect of history and culture in the leadership style and development of the country. 展开更多

In December 11,2018,the fall armyworm(FAW),Spodoptera frugiperda invaded China and has since impacted local maize,sorghum and other crops.Here,we draw on laboratory experiments to show how different host crops(i.e.,maize,sorghum,wheat and rice)and artificial diet affect larval growth and adult reproduction of one local FAW strain.Larval diet affected development duration,pupation rate,survival and emergence rate of pupae,and S.frugiperda adult fecundity.FAW attained the slowest larval development(19.4 days)on sorghum and the fastest(14.1 days)on artificial diet,with larvae attaining 99.6%survival on the latter food item.On rice,FAW larvae attained survival rate of 0.4%and were unable to pupate successfully.Pupation rate and pupal survival varied substantially between artificial diet and live plantlets at different phenological stages.Pupal weight was the highest(0.26 g)on artificial diet and the lowest(0.14 g)on sorghum,while FAW females reached the highest fecundity(699.7 eggs/female)on 2-leaf stage maize.Egg hatching rate equaled 93.6%on 4-or 5-leaf stage maize and 36.6%on artificial diet.FAW intrinsic rate of natural increase and the finite rate of increase varied between larval diets,reflecting how young maize leaves are the most suitable diet.Our findings can help to refine laboratory rearing protocols,devise population forecasting models or guide the deployment of‘area-wide’integrated pest management(IPM)modules in FAW-invaded areas of China and other Asian countries. 展开更多
