摘要
国内低渗透油田开发过去一直以注水为主 ,目前注水开发技术投资较大且与经济效益之间的矛盾十分突出 ,而提高采收率是油田开发工作者的最终目的 ,因此 ,研究更经济有效的开采方式是进一步提高低渗透油田开发水平的新课题 ,针对低渗透油田的特点 ,介绍了有发展潜力的注气法、微生物采油、化学驱、电动力学法、震动波法等提高低渗透油田采收率方法的原理、适用性及今后的发展方向。
In the past,injection water displacement is still a main recovery technology for low-permeability oilfield.The contradiction between investment and benefits for waterflood development is very prominent.Enhanced oil recovery is the final objective for petroleum engineers.So,study on more inexpensive and effective oil recovery methods is a new problem,which is further to improve development level of low-permeability oilfield.In this paper,the principles,applicability of all sorts of recovery methods for low permeability oilfield are intoduced,such as:gas injection,micro-biological oil recovery,chemical flooding,electroidynamics and vibration method etc..Finally,the technique development tendency and research of developing low-permeability oil field are put forward.
