Economic evaluation for full-cycle development of unconventional oil and gas and key parameters limits
摘要
Abstract
Compared to conventional development,unconventional oil and gas projects are characterized by large in-vestment,significant differences in stage benefits and high development risks.It is urgent to establish a scientific economic evaluation method to guide benefit decision-making.Starting from the entire process of project develop-ment and based on in-depth analysis of the economic characteristics of unconventional oil and gas development proj-ects,breakeven analysis and cash flow theory are used to incorporate technical parameters into the economic evalua-tion of unconventional oil and gas.An economic evaluation method for full-cycle development of unconventional oil and gas is constructed,covering 4 stages of project pre-demonstration,construction,production and operation and completion,and limits model for the main parameters of unconventional oil and gas beneficial development is estab-lished.Taking HJ block and DA block as examples,tight gas wells are selected to determine single-well daily pro-duction limit of the block,providing decision support for the effective production and efficient development of un-conventional oil and gas.The research indicates that the full-cycle economic evaluation method is suitable for evalu-ating unconventional oil and gas projects characterized by significant benefit differences and high risks,which can accurately reflect the benefit status at different project stages.The application of economic limit models for key pa-rameters enhances the foresight of investment decisions.The research provides technical support for efficient devel-opment of unconventional oil and gas.关键词
