曙二区杜家台油藏是辽河油田曙光采油厂稀油主力开发区块,从1975年杜7井投入勘探开发以来历经近40年的开发,由于含水高、采出程度高及油层非均质性影导致剩余油分布不均匀,使油藏开采难度逐渐增大,如何做好剩余油研究成为提高区块特高含水期开发效果的主要课题。 Shuji District Dujiatai reservoir is the main oil and light development block of Shuguang Oil Production Plant in Liaohe Oilfield. Since the exploration and development of Du 7 well in 1975, it has been developed for nearly 40 years. Due to high water content, The qualitative shadow causes the uneven distribution of remaining oil, which makes the difficulty of reservoir exploitation gradually increasing. How to do the remaining oil research becomes a major issue to improve the development effect of UHMW water blocks.
