摘要
边底水油藏在新疆油田分布较广,因而提高边底水油藏的开发效果至关重要。随着开采时间的延长,边底水侵入对油藏产量的影响日趋严重。针对边底水油藏不同的地质特征和开发阶段陆续开展了深部调驱的试验,不仅扩大了注入水的波及体积,而且抑制了边水的推进速度,油藏的开发效果得到了提高,同时,对如何搞好边底水油藏的调驱措施取得了一些认识。
It is very important to improve the development effect of edge-bottom-water reservoirs, for this kind of reservoirs widely distribute in Xinjiang oilfield. Due to more and more serious influences of edge water invading and bottom water conning on the production, pilot tests of deep profile control and oil displacement technologies are carried out in succession according to the different geological characteristics and development stages of the edge-bottom-water reservoirs. Through these tests, not only is the swept volume of the injection water enlal＇ged, but also the invading speed of the edge water is restrained, and the development effect of the reservoirs is improved. At the same time, some ideas about how to apply profile modification and oil displacement technologies to deal with the edgebottom-water reservoirs are gained from this study.
