摘要: 针对蒙古林稠油油藏粘度高,注水开发后含水上升快,产量迅速递减的实际,提出了应用可动凝胶调驱技术。介绍了蒙古林普通稠油油藏高含水开发条件下开展的从实验室到矿场实施、到效果评价的可动凝胶调驱先导试验技术研究和应用的概况,说明了可动凝胶调驱技术同时具有剖面调整、储层深部液流转向以及驱替的作用,可以作为一种驱替方式有效解决非均质性较强的普通稠油油藏后期水驱开发问题。矿场先导试验实施5年来已累积增油5.88×104t,获得良好的增油降水效果。

Abstract: Moveable gel (MG) displacement adjustment is a developing IOR/EOR new technology.It is also called improved polymer flooding or technical upgrading of polymer flooding.In this paper,the research and application of moveable gel displacement adjustment technology for Menggulin conventional heavy reservoirs from laboratory to field is introduced.It is indicated that MG displacement adjustment is of the advantages of both deep profile control and polymer flooding,and can effectively"plug"large pore channels,improve mobility ratio and solve the problems on both vertical and horizontal directions.As a kind of displacement mode,MG displacement adjustment can effectively solve water flood development problem of common heterogeneous heavy oil reservoir occurring at late stage of development.Since the beginning pilot test 5 years,the accumulative incremental oil has been 5.88×104t.The test has achieved good technical and economic effect.
