垦西斜坡带沙一段储层主要以生物灰岩为主,局部为砂岩储层。完钻见油气显示井较多,但除靠近南部垦西断层的垦24块上报储量472万吨,其余均未形成一定的储量规模。究其原因是沙一段在沉积体系、油藏类型、储层展布特征以及成藏规律等方面缺乏系统性认识,制约了该区勘探开发进程。随着地质认识的深入,勘探技术的发展,通过已钻井分析,本区沙一段生物灰岩滩坝勘探显示出较大的勘探潜力。
The reservoir of the first member of sand belt in Kenxi slope is dominated by biogenic limestone and is partially sandstone reservoir. Drilling oil and gas wells drilled see more, but near Ken Zhang southern Kennedy reclaimed reserves of 4720000 tons, the rest did not form a certain amount of reserves. The reason is that the first member of Shahejie lacked a systematic understanding of sedimentary system, reservoir type, reservoir distribution characteristics and accumulation law, which restricted the process of exploration and development in this area. With the deepening of geological understanding and the development of exploration technology, through the drilling analysis, the exploration of bio-limestone beach dam in the first section of this area shows great exploration potential.
