南苏丹G油田水平井开发影响因素及其灰色关联分析

Influential Factors and Grey Correlation Analysis of Horizontal Well Development in G Oilfield in South Sudan

水平井开发效果受到地质条件、开发方式及施工水平等因素的综合影响。根据灰色关联分析法原理,建立了南苏丹G油田边底水油藏数值模型,通过数值模拟计算得到了不同参数对应的开发指标水平,对各参数进行敏感性分析。根据灰色关联分析结果,对各影响指标由强到弱进行排序。

The development effect of horizontal well is affected by the geological, development and site operation parameters. By using the grey correlation analysis method, the reservoir numerical model of G Oilfield in south Sudan was established. By numerical simulation we calculated the development index and carried on sensitivity analysis under the influence of different parameters. According to the analysis results we defined the order based on the im- pact parameters from primary to secondary.
