海上注水油田水淹规律分析软件在渤海某油田中的应用

Application of water displacement performance analysis software system in Bohai oilfield

对于多层合采的注水开发油田,由于层间、层内及平面非均质性,容易出现平面舌进、单层突进的现象,导致部分区域、部分层段水淹现象严重,开发效果变差。为了提高油田开发效果,有必要研究油田的水淹情况,认识剩余油的分布规律,为后续油田综合调整提供依据。本软件结合海上测试资料少的特点,综合应用油藏工程理论,在动静态资料分析的基础上,逐层劈分注水量,结合实验水驱规律分析各层水淹状况,该软件系统操作简单,简化了工作量,提高了工作效率,对油田生产具有一定的指导意义。

For multilayer commingled production of waterflooding oilfield,because of interlayer heterogeneity,in-layer heterogeneity and plane heterogeneity,it is easy to have a phe-nomenon of fingering and tonguing,leading to worse water flooding degree and worse development efficiency.In order to improve the oilfield development efficiency.It is necessary to study water flooding degree and distribution of residual oil.This software according to the characteristics of the less sea trials the integrated application of reservoir engineering theory,based on the analysis of the dynamic and static data,step by step a split injection, combined with analysis of experimental law of water flooding water flooded condition of every layer.The software is operated simply and improve work efficiency,leading to a certain guiding significance in the oilfield production.
