Abstract: 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 enlarged, 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.

Key words: Xinjiang oilfield, edge-bottom-water reservoir, profile modification and oil displacement technology, development effect
