孤岛油田孤气九是具有边底水的断块稠油油藏,在蒸汽吞吐过程中存在着产量递减大、油层压力下降快的特点。为了进一步提高该断块剩余储量,增加采收率,拟转为蒸汽驱开采方式,本文在建立该断块油藏地质模型的基础上,运用数值模拟技术对蒸汽驱开发进行论证,为该断块实施汽驱提供了可靠依据。 Gudao nine orphan oil nine is a fault block heavy oil reservoir with edge water, there is a decrease in production during the steam huff and puff, the reservoir pressure drop faster. In order to further improve the remaining reserves of the fault block and increase the recovery rate, it is proposed to be converted to a steam flooding method. Based on the establishment of the geological model of the fault block reservoir, numerical simulation is used to demonstrate the development of steam flooding. Block implementation of steam flooding provides a reliable basis.
