Based on an analysis of the limitations of conventional production component methods for natural gas development planning,this study proposes a new one that uses life cycle models for the trend fitting and prediction of production.In this new method,the annual production of old and new wells is predicted by year first and then is summed up to yield the production for the planning period.It shows that the changes in the production of old wells in old blocks can be fitted and predicted using the vapor pressure model(VPM),with precision of 80%e95%,which is 6.6%e13.2%higher than that of other life cycle models.Furthermore,a new production prediction process and method for new wells have been established based on this life cycle model to predict the production of medium-to-shallow gas reservoirs in western Sichuan Basin,with predication error of production rate in 2021 and 2022 being 6%and 3%respectively.The new method can be used to guide the medium-and long-term planning or annual scheme preparation for gas development.It is also applicable to planning for large single gas blocks that require continuous infill drilling and adjustment to improve gas recovery. 展开更多

We present an efficient and risk-informed closed-loop field development (CLFD) workflow for recurrently revising the field development plan (FDP) using the accrued information. To make the process practical, we integrated multiple concepts of machine learning, an intelligent selection process to discard the worst FDP options and a growing set of representative reservoir models. These concepts were combined and used with a cluster-based learning and evolution optimizer to efficiently explore the search space of decision variables. Unlike previous studies, we also added the execution time of the CLFD workflow and worked with more realistic timelines to confirm the utility of a CLFD workflow. To appreciate the importance of data assimilation and new well-logs in a CLFD workflow, we carried out researches at rigorous conditions without a reduction in uncertainty attributes. The proposed CLFD workflow was implemented on a benchmark analogous to a giant field with extensively time-consuming simulation models. The results underscore that an ensemble with as few as 100 scenarios was sufficient to gauge the geological uncertainty, despite working with a giant field with highly heterogeneous characteristics. It is demonstrated that the CLFD workflow can improve the efficiency by over 85% compared to the previously validated workflow. Finally, we present some acute insights and problems related to data assimilation for the practical application of a CLFD workflow. 展开更多

The Sustainable Development Goals(SDGs)of the United Nations 2030 Agenda are a key focus for implementing the Sustainable Development(SD)concept.But generally speaking,SD goals and targets are continuously evolving,country specific,complex to implement,and are often given relatively short time horizons,such as the 15-year horizon for the SDGs.Many SD issues need a much longer time horizon as the policy interventions to deal with these issues can take decades before their effects become apparent,which is especially true for China.The T21 China 2050 is developed to study the long-term SD challenges and opportunities of the country.In its business-as-usual simulation to 2050,T21 China 2050 reveals some of the sustainability challenges facing China,including 1)aging population and labor force decline,2)huge food imports,3)land degradation and loss of arable land,4)water shortages,5)huge fossil fuel imports,and 6)carbon dioxide emissions.These SD issues are a subset of the SDGs specifically relevant to China over a time horizon well beyond 2030.The model is then used to test possible policy interventions in these six areas under two separate scenarios:Balanced and Narrowly Focused.The major results from these two scenarios are compared with those of the business-as-usual scenario.The simulations show that by adopting certain policy measures,China’s path towards SD can be further improved.It also shows that a variety of policy measures can be selected and tested with the T21 China 2050 model for exploring the future SD prospects of the country.Specific policies recommended include:extension of retirement age,adjustment of the current family planning policy,protection of agriculture land,promotion of agricultural R&D to raise yield,improvement of public transportation to slow private vehicle ownership,increased investment in renewable energy,and water conservation. 展开更多

Regional development planning is one of the 'hot spots' in the field of human geography in China Based on brief retrospection and reviewing of its development since the 1980s, this paper discusses the basic thoughts of regional development planning under the socialit market economy, i.e.,to work out planning of flexibility, sustainability, multi-objective coordination and high effective practicability. In line with these thoughts, the paper puts forwards boo countermeasure in the practice of working out a high effective regional developmed planning. These countermeasures are to strengthen research on market factors, to take the coordinated development between the economy,society and PRED as the main line of regional development to correctly deal with the relationship between qualitative analysis and quantitative research and to emphasize on researches of regional policies. 展开更多

Equipment development planning(EDP)is usually a long-term process often performed in an environment with high uncertainty.The traditional multi-stage dynamic programming cannot cope with this kind of uncertainty with unpredictable situations.To deal with this problem,a multi-stage EDP model based on a deep reinforcement learning(DRL)algorithm is proposed to respond quickly to any environmental changes within a reasonable range.Firstly,the basic problem of multi-stage EDP is described,and a mathematical planning model is constructed.Then,for two kinds of uncertainties(future capabi lity requirements and the amount of investment in each stage),a corresponding DRL framework is designed to define the environment,state,action,and reward function for multi-stage EDP.After that,the dueling deep Q-network(Dueling DQN)algorithm is used to solve the multi-stage EDP to generate an approximately optimal multi-stage equipment development scheme.Finally,a case of ten kinds of equipment in 100 possible environments,which are randomly generated,is used to test the feasibility and effectiveness of the proposed models.The results show that the algorithm can respond instantaneously in any state of the multistage EDP environment and unlike traditional algorithms,the algorithm does not need to re-optimize the problem for any change in the environment.In addition,the algorithm can flexibly adjust at subsequent planning stages in the event of a change to the equipment capability requirements to adapt to the new requirements. 展开更多

In this paper, we construct a model to distinguish the sustainability of a country. To evaluate the sustainability of a country, we select eight metrics based on four aspects: Society, Economics, Ecology and Politics. We use BP neural network to obtain the sustainability ranking and use Grey Relational Analysis to calculate the sustainability scores of 187countries. By combining the ranking and the score, we develop a measure to define whether a country is sustainable or not. The critical point is Maldives, which ranks No. 103 and scores 63.65. As one of least developed countries, Uganda ranks No.164 and scores 48.79, according to our measure. Based on Uganda' s society, population, natural resources, etc., we draft a 20-year (2013-2033) sustainable development plan that integrates the social, economic, ecological and political components. The overall goal of the plan is to transform Uganda into a sustainable country and make noticeable progress in the ranking. Furthermore, to analyze changes' influence on our plan, we take climate change as an example. The weights of Environment and Health will be modified by climate change, causing a reduction in the growth rate of sustainability score. 展开更多

The domestic tourism development planning began in 1985. According to the research achievement distribution situation, tourism development planning research can be divided into initial stage( 1985-1998), development stage(1999-2004) and prosperous stage(2005 till now). The research achievement has the features of earlier academic research start, slow quantity increase, rapid growth of newspaper quantity, wide distribution of region, research achievement total increase speed slower than social scientific research achievement quantity growth. The research has three aspects of problems: one is insufficient academic research system; two is report lacks of depth, continuity and unity; three is research achievement has overall decreasing trend. The domestic tourism development planning should strengthen the theoretical research, combine with theory and practice; strengthen thematic reports, mining depth information, and give full play to supervision function. 展开更多
