基于生产潜力的深水油田井位优化方法及应用

深水油田的井位优化是基于油藏特征、流体性质、钻井建设、平台设施及经济界限等多学科的高风险复杂系统工程。立足深水油田的地质、油藏、作业环境和经济效益要求,以高效开发和快速部署为目标,以＂稀井网、大井距＂条件下地质精细建模和油藏数值模拟为手段,提出一种基于改进型生产潜力指标的深水油田井位优化方法。西非某深水油田应用实际表明,该井位优化方法可获得更高的采油速度和采出程度,有利于缩短投资回收期,实现深水油田开发效果和经济效益最优化,对深水油田井网部署具有一定的实用价值和理论指导意义。

Method and application of well location optimization in deepwater oilfield based on productivity potential

The well location optimization of deepwater oilfield is based on the complex interdisciplinary system engineering with high risk and reservoir characteristics of fluid properties,wellbore construction,platform facilities and economic limits.Based on deepwater oilfield geology,reservoir,environmental engineering and economic benifits,taking high efficiency development and rapid arrangement as target and taking stochastic modeling and reservoir simulation as a means under the deepwater oilfield of ＂sparse well pattern,large well spacing＂ conditions,a well location optimization method of deepwater oilfield with improved productivity potential index and strong practicality is proposed.Applications of deepwater oilfield in West Africa shows that this method can be used to achieve higher production rate and recovery and to shorten the payback period to obtain the effect of deepwater oilfield development and the economic benefits,having certain practical value and guiding signification for the well pattern arrangement of deepwater oilfield.
