化学深部调驱技术现状与进展

Current situation and development of chemical deep oil displacement regulation technology

油田在高含水期,常规的堵水调剖技术已不能满足油田生产需求。深部调驱技术的研究及应用等取得了许多新进展,在改善高含水油藏水驱开发效果方面获得了显著效果。在综合调研国、内外有关深部调驱剂的研究和应用基础上,本文介绍了凝胶类深部调驱剂、微生物深部调驱剂、泡沫深部调驱剂及组合调驱体系,提出了今后深部调驱剂的主要发展方向。

Oil fields at high water cut stage, the conventional technologies of profile contorl and water shutoff can no longer meet the demand for oil field production. The new progress of deep profile control technology research and application has been made. At high water cut reservoirs to improve the development effectiveness of water flooding gained significant effect. Base on investigation of the research and application of deep profile control and flooding agent both home and abroad, this paper introduces the gel-type deep profile control and flooding agent , micro- organisms deep profile control and flooding agent, foam deep profile control and flooding agent and combination- profile control and flooding system,then the development directions of deep profile control and flooding agents in the future was proposed.
