确定油气储量起算标准的新方法

New methods of determining commercial flow rate well in oil and gas reserves estimation

"油气储量起算标准确定方法"是储量计算中关键而又敏感的问题,长期以来未得到有效解决。根据多年来的储量计算与评价研究,认为可从单井储量价值评估入手,以单井的投入、产出盈亏平衡为条件,采用将未来采出量折算成现值产量的新方法,研究该井回收产能建设投资的最低经济可采储量,作为储量起算标准,由此测算不同稳产年限或递减率条件下的稳定日产量。分别以川渝地区2口油气井为例,说明了具体的确定方法。

In reserves estimation,the method of 'determining commercial flow rate well in oil and gas reserves estimation' has been a key and sensitive issue,which has not yet been effectively resolved for a long time.Based on the reserve calculation and the estimation experiences in so many years,we can start the reserve estimation of a single well,using the condition of a single well's inputs and outputs break-even,then adopt a new approach to convert the future output to present value production,studying the minimum economic recoverable reserves of the well (or new drilling) in net present value of paying off the building capacity investment,and finally making it as the starting date standard,use this standard to reckon stable daily output based on the condition of different years of stable production or variable decline rates.The determination of specific ways is explained by two oil and gas wells in Sichuan and Chongqing gas fields.
