摘要
海洋油气开发具有高风险、高投入和受海上环境条件限制等特点,而平台位置的选择问题是影响开发成本、钻完井难易程度的首要问题。针对平台位置优选问题,通过对海上丛式井平台位置选择因素分析,利用DecisionSpace软件的最小进尺法和权重法选择平台位置,综合考虑总进尺数和作业难度,采用均匀布点法和位置加密法相结合的方式得到最优平台位置。最后以渤海某平台为例进行了技术应用分析,优选出的平台位置既满足总进尺数较小又能满足作业难度较低的要求。结果表明该技术方法应用效果较好,对海上平台位置优选具有现实指导意义。
The offshore oil and gas development has the characteristics of high risk, high investment and restriction by marine environment. The platform location selection is the most important problem affecting development cost and well drilling and well completion. In this paper, the research on location optimization method of offshore platform for cluster wells is carried out. The selection factors of the platform location optimization are analyzed. The platform location is selected by minimum drilling footage method and weight method based on the software DecisionSpace, then the optimized platform location is determined with the combination of minimum drilling footage method and weighting method in comprehensive consideration of total drilling footage and operation difficulties. This location optimization method is applied in an offshore platform in Bohai Sea for example, the optimized platform location has the features of shorter drilling footage and less operation difficulty, which proves this method has a good applied effect.
