摘要
目前渤海油田已投产的部分油田存在含水率上升快、采出程度低的突出问题,而受平台的寿命限制,一个海上油田的开发只有20年左右的时间。如何在平台寿命的有效期内,尽快地采出更多的油,是渤海油田需解决的技术难题。通过对旅大10-1油田的地质油藏分析,建立合理的地质模型和油藏数值模型,从而进行驱油方案的优化设计研究,给出了推荐方案。研究结果表明,在旅大10-1油田进行早期注聚合物是可行的,但存在一定的困难,注入速度不能太高,段塞质量浓度也不能太高。
There are some prominent problems nowadays that water cut rises quickly and the recovery percent is low for some fields put into production in Bohai offshore oilfield. And because of the limit of the platform life span, an offshore oilfield will be developed for only twenty years. So it is a difficult technology problem to be solved that how to produce more oil as quickly as possible during the platform life span. Through analyzing the geology and reservoir quality of LDIO-I oilfield, the reasonable geologic model and reservoir numerical model are developed, based on which the optimized design study of polymer flood project has been carried out, and finally the recommended projects are given in this paper. The study indicates that it is feasible to early inject polymer at LD10-1 oilfield, but it has some difficulties that both the polymer injection rate and the slug quality concentration cannot be very high.
