复杂断块油藏中后期措施挖潜对策研究与实施

Research and Implementation of Measures for Potential Tapping of Complex Fault Block Reservoirs in the Middle and Later Stage

辽河油田已开发40多年,已经进入开发的中后期,储层动用程度逐渐升高,措施挖潜难度逐渐加大,效果逐年变差,因此,有必要进行措施挖潜对策研究,深入挖潜油田剩余潜力,提高油田采收率。本文主要介绍了,辽河油田复杂断块油藏开发中后期措施挖潜的理念的转变,以及关键技术手段的应用,充分挖潜剩余油,改善油田开发效果。

Liaohe oilfield has been developed for more than 40 years,and has entered the middle and late stages of development.The reservoir utilization level is gradually increasing,the difficulty of potential tapping is gradually increasing and the effect is getting worse year by year.Therefore,it is necessary to carry out research on measures to potential tapping,tap the remaining potential of the oilfield and improve the petroleum recovery rate.This paper mainly introduces the transformation of the concept of exploiting the latent energy in the middle and late development of complex fault block reservoirs in Liaohe Oilfield,as well as the application of key technical means,fully excavate the remaining petroleum and improve the effect of oilfield development.
