摘要
针对海外含众多断块的油田群经济高效动用顺序优化问题,运用层次分析法,考虑各个断块油藏关键技术经济指标,通过建立指标体系,构建层次分析模型,指标归一化,形成标准因子集,确定要素权重和计算综合因子等流程,可有效地对数量众多的断块进行定量评价,实现投产顺序的优先级排序。根据优化结果,考虑海外实际开发形势,还可划分出主力建产和接替稳产两部分。该方法对于海外其他类似分散多数量断块油田群的高效开发具有重要参考价值和借鉴意义。
Aiming at the issue of optimizing economic and efficient development sequence of the overseas faultedblock oilfield groups containing a great many of reservoirs,analytic hierarchy process and fuzzy mathematics theory are utilized to quantitatively evaluate and determine the order of development sequence priority effectively considering different attributes of each faulted-block reservoir.The whole evaluation process includes establishment of index system and a hierarchical analysis model,index normalization,foundation of a standard for subset,factor weights determination,and comprehensive factor calculation.According to the optimization result,considering the actual situation of overseas development,all oilfields could be divided into two parts.High quality blocks with higher comprehensive factor could be main production contributorin preliminary stage.Poor quality blocks with lower comprehensive factor could be successive contributor for stable production in later stage.This optimization method has important reference value for the efficient development of other similar faulted-block oilfield groups containing a great many of reservoirs.
