研究储层非均质性是油田开发地质中最重要的工作之一。本文以储层的基础数据和渗透率的非均质参数为依据,论述了双河油田储层平面-层间-层内-孔道的非均质特性,研究了成岩后生作用及影响非均质性的因素。利用模糊数学模型:(?),对储层进行了综合评价。在沉积模式研究的基础上,建立了三维数值非均质模式,可以模拟出任何注采井组渗透性及其非均质性的纵横向变化,推论油藏可能出现的注水动态,为探求有效的油水流向,提高开采效果提供地质依据。
Research on reservoir heterogeneity is one of the most important tasks in oilfield development. Based on the non-homogeneous parameters of reservoir basic data and permeability, the paper discusses the heterogeneity of reservoir plane-interlayer-layer-borehole in Shuanghe Oilfield, studies the diagenesis and heterogeneity Sexual factors. Using fuzzy mathematical model: (?), A comprehensive evaluation of the reservoir. Based on the study of depositional model, a three-dimensional numerical heterogeneity model was established to simulate the vertical and horizontal variations of permeability and heterogeneity in any injection-production well group, and to infer possible waterflooding dynamics in reservoirs. In order to seek effective Of the flow of oil and water to improve the mining effect to provide geological basis.
