摘要

利用压力恢复曲线确定单井控制储量的绝大多数方法,是基于时间来求取油井实际泄油面积,进而利用容积法求取单井控制储量。如果测试数据波动较大,或者没有测得所需时间点,以上方法求取单井控制储量就会受到极大限制。该文提出了一种基于地层压力来求取油井控制储量的新方法,避开了以上基于时间求取控制储量的种种限制,利用压力恢复曲线径向流直线段数据计算出油井实际泄油面积,从而得到油井控制储量,并通过实例分析论证了此方法的可靠性和有效性。
The methods for calculating the single well controlled reserves by pressure build up curve are mostly using time to calculate the single well drainage area,and then apply volumetric method to obtain single well controlled reserves.If the test data is undulatory or not determined,it will be hardly to get the single well controlled reserves.A new method for single well controlled reserves based on pressure is proposed,which can avoid the limits of the methods based on time.It uses Horner straight line to calculate the single well drainage area,and then obtain the single well controlled reserves.The practical application result proves the reliability and validity of this method.
