摘要
海上油田开发投资巨大,不准确的产能评价结果将会给油田的勘探开发工作带来严重的影响。为了得到较高精度的产能预测方法,本文基于不同水淹状况下的单层流入动态分析方法,开展多层合采时流入动态叠加方法的研究,获得了多层合采时单井产油量的公式,并引入干扰校正系数,从而建立油藏单井初期产能预测方法。通过在渤海S油田的实例运用,将计算数据与现场生产数据对比,吻合较好,证明该研究方法具有可行性。
The investment in offshore oilfield development is huge,and the inaccurate productivity evaluation results will have a serious impact on the exploration and development of the oilfield.In order to obtain a high-precision productivity prediction method,based on the single-layer inflow performance analysis method under different water flooding conditions.This paper studies the inflow performance superposition method during multi-layer combined production,obtains the formula of single well oil production during multi-layer combined production,and introduces the interference correction coefficient,so as to establish the initial productivity prediction method of single well in reservoir.Through the application in Bohai S oilfield,the calculated data are compared with the field production data,which is in good agreement,which proves that the research method is feasible.
