我国长期实行计划经济体制 ,气藏开采的经济性往往被忽略 ,采收率主要反映了技术可采性。在目前市场经济条件下 ,油气生产企业最关心的是气藏开发能够获得最大经济效益的采收率 (即经济采收率 )。因此 ,研究气藏经济采收率 ,应用于气藏开发可行性论证 ,指导气藏科学开发 ,为油气生产企业决策者提供依据。文章采用经济极限产量法和现金流量法研究气藏经济采收率 ,从经济评价角度研究气藏采收率 ,使采收率不仅反映了技术的可采性 ,而且反映了经济的可采性。
China’s long-term implementation of the planned economic system, the economic exploitation of gas reservoirs are often overlooked, mainly reflects the recovery rate of technical admissibility. Under the current market economy conditions, oil and gas production enterprises are most concerned about the recovery rate (ie, economic recovery rate) that can maximize the economic benefits of gas reservoir development. Therefore, the study of economic recovery of gas reservoirs, applied to the feasibility study of gas reservoir development to guide the scientific development of gas reservoirs, oil and gas production enterprises to provide decision-makers to provide the basis. In this paper, economic limit recovery method and cash flow method are used to study gas recovery rate of gas reservoirs. Gas recovery rate is studied from the perspective of economic evaluation. The recovery rate not only reflects the admissibility of technology, but also reflects the admissibility of economy .
