摘要/Abstract

摘要： 针对化学驱油过程中产量增幅快、含水波动大、集中见效时间短的特点,探讨应用修匀-等比递减法标定化学驱可采储量。对年产油量数据序列开始出现明显波动的阶段进行修匀,生成一个新数据序列。对修匀后的新数据序列采用等比递减法,回归计算生产指标。通过对孤东油田小井距实际资料的计算,证明该方法可靠性较高。此外,还对七区西5₂₊₃的资料进行了计算,结果可信度较高,证明该方法尤其适用于化学驱油阶段指标计算,具有推广应用价值。

Abstract: In light of characteristics of large incremental production rate, varied water cut and short response time, the graduation- geometric proportion lapse method used to calibrate chemical flooding recoverable reserves is discussed. The graduation can be made for phase of obvious fluctuation emerged in annual output data serial, generating a set of new data serial, which is applied for calculation of production index by regression with geometric proportion lapse method. Through calculation with small spacing data from Gugong oilfield, the method is verified to be more reliable. So does the calculation with data from 5₂₊₃ Well Block of west of District 7 in the field. Hence, it is indicated that this method is especially applied for calculation of recoverable reserves in chemical floding process and possesses values for deployment.
