大庆油田特高含水期采油工程研究现状及发展方向

Status quo and future development of production engineering at high water cut stage in Daqing oilfield

大庆油田已开发44年,进入特高含水开发阶段,油田开发面临着含水高、采油速度高、储采失衡严重、套损速度加剧等一系列问题。如何提高油田最终采收率是油田开发面临的主要问题,也是采油工程面临的最大挑战。在简要介绍了大庆油田在特高含水期采油工程的总体技术需求的基础上,分析了采油工程技术现状及存在的主要问题,提出了采油工程技术的发展方向。

After 43 years ' development Daqing oilfield has entered specially high water cut stage and a series of problems, such as high water cut, high oil production rate, underbalanced reserve-production ratio, increasing casing damage rate, and so on, occur before us. How to increase the ultimate recovery factor of oilfield is not only the main problem for oilfield development but also the largest challenge to production engineering. In this paper the total technical requirements of production engineering for Daqing oilfield at specially high water cut stage are briefly introduced, the status quo and main problems of production engineering are analyzed and the further development is advanced, which are significant to the sustainable development of Daqing oilfield.
