底水油藏油井合理射开程度研究

<title>udy on rational perforation degree of oil wells in reservoir with bottom water .

通过对渤海锦州9-3油田底水油藏地质资料的分析,建立了不同水体倍数及不同射开程度的地质模型;利用数值模拟方法,研究了不同能量的底水油藏对应的合理射开程度以及在该射开程度下的开发指标。通过模拟计算结果的分析,绘制了底水油藏确定合理射开程度的理论图版。

<abstract>ologic models of reservoir with bottom water were build at various aquifer water multiple and perforation degree after analyzing geologic data of the bottom water reservoir in Bohai Jinzhou 9 -3 oilfield. The rational perforation degree and the corresponding development index of the reservoir with different energy were studied by numerical simulation. After analyzing the simulative calculation results, a theoretical chart board was drawn up which can determine the rational perforation degree in the bottom water reservoir with different aquifer size and the different ratio of vertical to horizontal permeability.
