S油田是被多条断层切割为三个台阶的断垒油藏,油藏埋深在1700-1900m,属于浅层油藏[1]。主要目的层为古近系Sokor1组,为陆相河控三角洲沉积[2]。该区纵向上发育三套含油层系,分别为E1、E2和E3油组。经过2年多的开发,出现了初期产量高、递减大,含水上升快等问题,需要继续深入开展油田精细地质研究及动态跟踪分析,提出合理稳产对策,确保该油田产量稳定,并为后期类似油田提供开发经验。 S oilfield is a fault block reservoir cut into three steps by multiple faults. The reservoir depth is between 1700 m and 1900 m and belongs to the shallow reservoir [1]. The main target is Paleogene Sokor1 Formation, which is continental facies controlled delta deposition [2]. There are three sets of oil-bearing strata longitudinally in the area, which are E1, E2 and E3 oil groups respectively. After more than two years of development, problems such as high initial output, declining, and rising water cut occur. We need to continue to carry out in-depth study on fine geology and dynamic tracking of oilfields and put forward reasonable measures for stabilizing production so as to ensure the stable output of the oilfield. Oilfield to provide development experience.
