求准断块油田含油储层体积的关键在于算准计算单元的含油面积与有效厚度参数。本文结合东濮凹陷各油田多年储量计算经验及油田开发工作实际,开展了含油边界圈定和有效厚度取值方法研究,得出针对不同油藏类型应采用相应的含油边界圈定方法,各计算单元有效厚度取值应以井点面积权衡法为基础的认识。

The key to get high precision of the oil bearing reservoir velume is precision of the oil bearing area and effective thickness in Fault - - Block Oilfield , the authors integrate the practice of every Oilfield in computing OOIP Dongpu Depression and the practice of oil development for many years , developed the study of methods how to determine the oil bearing area and take the value of thickness. With the study , reveal the method how to determine the oil bearing area with different methods in different types of reservoirs , and the authors think the wellpoint - area - method is more reasonable than other methods.
