摘要： 提出了一种确定未饱和油藏油井单井控制储量的新方法,该方法从拟稳态渗流方程出发,通过推导可以很方便地确定油井单井控制储量。使用该方法不需要进行关井测压,只需要阶段日产油和累积产油量以及原始油藏压力和井底流压等动态数据,通过线性回归,并进行外推即可得到单井控制储量。实例表明,由该法得到的单井储量与静态单井储量非常接近,是一种简单、实用、准确、可靠的确定油井单井储量的新方法。

Abstract: This paper presents a new method for determination of reserves controlled by single well in unsaturated oil reservoir. From pseudo steady state percolation equation, single well-controlled reserves can be determined easily through simple derivation of the method. With this method, shut-in pressure is unnecessary. Only dynamic data such as stage daily production and cumulative production and initial reservoir pressure and bottom-hole pressure are required. Through linear regression and extrapolation, single well-controlled reserves are attained. The case study shows that the reserves determined by this method are well close to the static single well reserves. Therefore, this method is simple, applicable, accurate and reliable.

Key words: unsaturated oil reservoir, oil well, controlled reserve, percolation
