文档介绍：胜利油区提高采收率技术调研
摘要<br均采收率只有33%左右,约有三分之二的储量将留在地下,而胜利油区的注水开发面临着很大的难题,有的油井含水率已高达98%,开发的效益可想而知。本篇提高胜利油区采收率方法调研主要针对以下三种类型油藏:高含水油藏、低渗油藏、稠油油藏;重点调研每一种方法的适用条件、基本原理、及矿场应用。此三类油藏的开发对提高整个胜利油区的产量是至关重要的,另外结合国内外三次采油新工艺的总结与创新利用调研把国内外对提高此类油藏采收率的方法与胜利油区的实际情况相结合,理论联系实际,用以帮助提高胜利油区的采收率。

The Investigation of EOR in Shengli Oilfield
Abstract
The average recovery inland using conventional watterflooding method is only 33%, two thirds reserves are resided underground, shengli oilfield faces great problems in watter flooding development. In some oil wells, water-cut has arrived 98%, thus, the development effenciency is paper is mainly about three types of reservoirs: hightwatter reservoir,low permeability reservoir, imspissated pool;and mainly research: the suitabal condition, basic principle, lease application of every methods. the development of this three types of reservoir do a great role in production of shengli oilfield. Additional, with the innovation and conclution of the tertiary recovery, we shoud connect the method in and out with shengli oilfield and make theory into practice, to improve the recovery factor of shengli oilfield.
