陆梁薄层底水油藏产水规律

在建立了陆梁薄层底水油藏地质及渗流模型基础上, 采用理论研究的方法, 研究了薄层底水油藏采出程度与含水率关系式, 并获得了油厚比、油水粘度比、相渗曲线特征参数以及底水锥进等对油藏产水规律的影响关系图版。对典型井的产水规律综合研究表明, 理论曲线与油藏实际产水情况比较吻合, 说明该方法对薄层底水油藏产水规律分析预测具有较好的适用性。

Analysis of Water-Yielding Pattern of Thin and Bottom Water Reservoir in Luliang Oilfield, Junggar Basin

The theoretical study of the recovery percent vs. water cut of thin and bottom water reservoir in Luliang oilfield is based on developing its geologic and flow models, obtaining oil-thickness ratio, oil-water viscosity ratio, relative permeability curve parameter and chart of effect of bottom water coning, etc., on water-yielding pattern of the reservoir. The comprehensive research of typical wells in water-yield pattern shows that the theoretical curves are accordant with actual situation, indicating this method is applicable to analysis and prediction of water-yielding pattern in such a reservoir.
