驱油技术的发展及应用前景

Development and Application Prospect of Oil Displacement Technology

目前,我国大部分油田都已经进入高含水开发的中后期阶段,面临着减产速度过快、油田采出液含水率高、稳产难度大等一系列问题。如何提高油气采收率成为了油田今后面临的重要任务。本文重点对比分析最常见的驱油技术,指出各种驱油技术的工作原理及优缺点,同时本着"理论结合实践"的原则,对各种驱油技术取得的实际成果一一介绍,重点介绍最近出现的新型驱油技术。为油田如何提高油气采收率提供理论支持以及实际应用上的经验。

At present, most of the oilfields in China have entered the middle and late stage of high water-cnt development, and face a series of problems, such as rapid production reduction, high moisture content of oilfield produced liquid and difficulty of stable production. How to improve oil and gas recovery of oil field has become an important task in the future. In this paper, common oil displacement technologies were compared and analyzed; the working principle, advantages and disadvantages of various oil displacement technologies were pointed out. At the same time, based on the principle of combining theory with practice, the actual application results of various oil displacement technologies were introduced.
