摘要
随着油田含水的上升、采出程度的增加以及剩余可采储量的减少,油田稳产难度越来越大.为了保持油田更长期的高产稳产,需要研究、发展一批新的、能够进一步提高采收率的强化采油工艺.本文介绍了其中的一批比较重要的进展,包括:高弹性驱;无碱活性剂;同井注采工艺;开采和集输高凝、高粘油的工艺以及适合化学驱的采油工艺.
China is the country that implements IOR(including EOR)on the largest scale in the world; it also has achieved many breakthroughs in the above technologies.However,with the increase in water cut(Daqing Oil Field’s water cut is already 92%,other mature fields in China have a water cut of about 90%also),increased recovery ratio and decrease in recoverable reserves,it is getting more difficult to maintain the production stable.In order to maintain the production rate stable for a longer period of time,a new se...
