油田开发调整措施决策系统研究
|
摘要
任何油藏开发到一定阶段,随着含水率上升、油田产量递减、剩余油呈零星分布,这些都是其必经阶段,因此到油藏开发中后期,必然要对油藏制定相应的开发技术政策,采取必要的开发调整措施,延缓产量递减和减缓含水上升率,因此有必要先对油藏的前期开发策略和开发现状做出合理的评价,弄清油藏的开发历程和开发现状,找出开发过程中的矛盾所在,为后期的开发政策调整研究打下基础。
油田随着含水率的增加,都要采取各种措施进行综合治理,以改善水驱开发效果。在这些措施中,如何评价这些措施方向,从而为选择最优的措施提供依据是重要的,选择的指标不同,其结果就不同,这为油田工作者选择提出了难题。为了实现油田控水稳油,最大限度的挖潜地下剩余油,延长油田的稳产期,运用最优化方法、模糊数学理论、层次分析理论,结合油藏的实际特征参数,建立油藏水驱开发潜力指标评价体系及多因素综合评价方法,形成理论体系,对开发效果进行评价及为调整措施提供决策。油田在水驱的情况下,对压裂、堵水、调剖、补孔等油层措施以及动态分析与开发现状评价等方案的调整,是提高采收率的关键。文中对这几种措施进行了适应性分析,并研究了优化方法。重点对调剖措施进行了研究,确立了决策因子,对调剖措施效果进行分析和评价。
本文将模糊数学理论、最优化理论、层次分析法、复相关系数法和变异系数原理应用到油田开发效果评价和调整措施优化中。针对以前评价方法的可操作性差,缺乏系统性和全面性,应用系统工程理论和方法分析水驱油田的开发系统,确定了影响水驱开发效果的信息表征体系,建立了油田地质评价指标标准和地质评价方法;建立了油田水驱开发效果评价指标标准和开发效果评价方法。重点研究了压裂、补孔、调剖措施优化方法。最后对不同调整措施和方案开发指标进行预测,并作出技术经济评价。
应用Microsoft Visual Basic 6.0开发语言将论文中理论方法研制成油田开发调整措施决策系统软件,该软件功能齐全结构合理,具有开放性、先进性、安全性、方便性和实用性。并用实际数据进行计算,证明其理论方法可靠,软件运行稳定,适用性强。
