H区块萨尔图油层水淹层解释方法研究及应用

On the Interpretation Method of Water Flooded Layers in Shaertu Reservoir of H Block and Its Application

为实现红岗北H区块萨尔图油田稳产,应用不同开发阶段密闭取心井的各种动静态资料、试油资料、测井资料等,在曲线模式识别法定性解释水淹层和储层参数精细解释的基础上,综合利用动态电阻率下降法的半定量解释和驱油效率法的定量求取剩余油饱和度与含水率,形成1套符合油田实际的综合判别水淹级别的解释方法,能指导新井解释及剩余油评价,实现油田的长期稳产。

Using various static ＆- dynamic data, testing data and wireline logging data in different pressures coring wells, based on qualitative interpretation of water flooded layers with curve model evaluation method and fine interpretations of reservoir parameters and combining semiquantitative interpretation method of dynamic resistivity descending and quantitative interpretation method of oil displacement efficiency, proposed is a set of comprehensive methods of evaluation of water flooded grades that fit for oilfield practice. It can guide interpretation and evaluation of remaining oil in new wells, and resulting in long period stable production in the oilfield.
