In this paper,based on the study of Chenopodium quinoa Willd.planting,it is concluded that the current situations of large-scale development of C.quinoa Willd.include the following four aspects:first,the research on C.quinoa Willd.varieties needs to be strengthened;second,it is insufficient to master the training environment and cultivation techniques;third,the large-scale planting of C.quinoa Willd.is not enough;fourth,the degree of mechanization of C.quinoa Willd.planting is not enough.In view of the above situation,this paper puts forward the following effective suggestions to strengthen the large-scale development of C.quinoa Willd.:the first is to increase the investment in C.quinoa Willd.variety research;the second is to strengthen the analysis of introduction and screening of C.quinoa Willd.varieties;the third is to study the best planting environment and cultivation techniques of C.quinoa Willd.;the fourth is to increase the scale of mechanized production of C.quinoa Willd.;the fifth is to increase the research and development of C.quinoa Willd.related products and their deep processing technology. 展开更多

Designing special well patterns, tridimensional reservoir development selects a variety of wells and uses the gravity energy to maximize the hydrocarbon recovery. It's a new development model to implement the oil and gas exploitation economically and efficiently. It is suitable for both huge oiliness altitude reservoirs and large dip-angle sandstone reservoirs, and more for the carbonate reservoirs developed in high-angle fractures, volcanic reservoirs and metamorphic reservoirs. 展开更多

Multilateral wells promise cost savings to oil and fields as they have the potential to reduce overall drilling distances and minimize the number of slots required for the surface facility managing the well.However,drilling a multilateral well does not always increase the flow rate when compared to two single-horizontal wells due to competition in production inside the mother-bore.Here,a holistic approach is proposed to find the optimum balance between single and multilateral wells in an offshore oil development.In so doing,the integrated approach finds the highest Net Present Value(NPV)configuration of the field considering drilling,subsurface,production and financial analysis.The model employs stochastic perturbation and Markov Chain Monte-Carlo methods to solve the global maximising-NPV problem.In addition,a combination of Mixed-Integer Linear Programming(MILP),an improved Dijkstra algorithm and a Levenberg-Marquardt optimiser is proposed to solve the rate allocation problem.With the outcome from this analysis,the model suggests the optimum development including number of multilateral and single horizontal wells that would result in the highest NPV.The results demonstrate the potential for modelling to find the optimal use of petroleum facilities and to assist with planning and decision making. 展开更多

As China entered into a new era of development, the primary contradiction facing Chinese society has also evolved. It is important for both scholars and policymakers to review the characteristics of China's economy in its present stage in accordance with economic principles-principles that reflect every aspect of economic and social life and macroeconomic regulation. In this paper, we attempt to unravel the characteristics of China's new era from three perspectives-historical materialism, dialectic materialism and epistemology, and in light of economic principles at the three levels of resource factors, modes of production and regulation of resource allocation. Based on these perspectives, this paper further identifies the characteristics of China's new era from nine aspects, including globalization, modernization, the primary stage of socialism, new development concepts, supply-side reforms, the guideline of seeking steady progress, the mentality of scope, bottomline mindset and strategic composure. From the three different levels, this paper summarizes and applies economic principles to propose solutions to the problems and challenges facing China in the new era. The findings of the paper are also relevant to implementation of the guidelines CPC Central Committee General Secretary Xi Jinping noted in his report to the 19 th CPC National Congress. 展开更多
