新北油田开发对策研究

Research on the Countermeasures of Xinbei Oilfield Development

为了更好的解决新北油田在开发过程中存在的问题,在建立地质模型的基础上,应用油藏工程、数值模拟等方法,对开发方式、注采比、注水时机、射孔层位进行优化,结果表明在饱和压力环境下注水开发效果好,同时注采比取1.0。针对部分井区存在气顶的问题,对射孔进行优化,采用气顶气不动用的开采方式,取得良好的开发效果。

In order to solve the problems during the recovery of Xinbei Oilfield, a geologic model was built. The method of oil recovery, ratio of water flooding and oil recovery, water flooding time and perforation zone were optimized by using petroleum engineering, numerical simulation, etc. The results show that the water flooding effect is better under the saturated pressure condition with ratio of flooding and recovery being 1.0. The perforation was optimized to solve the gas cap problem in some wellblocks. The recovery effect is good when gas cap is not produced
