摘要
以某油田FST研究区块密井网资料为基础,应用油藏精细描述技术,对某油田FST研究区块的储层沉积特征、储层裂缝特征、水淹情况及剩余潜力分布作了进一步分析、研究。根据研究结果,指导了射孔及压裂方案的编制;调整并完善了注采关系,共增加水驱厚度61.8m,增加水驱动用储量16.1×104t;改善了主力层和非主力层动用状况,调整井区40口油井,日产油增加3.1t/d,含水率下降1.1个百分点;指导注水调整,缓解层间矛盾;指导单井产能改造,累计增油4419.2t。
Based on the thick well-pattern data from FST study block in an oilfield,reservoir sedimentology, fractures ,water encroachment and remaining oil potential are further analyzed and researched for the block by applying refined reservoir description.The results have guided us to design perforation and fracturing plans, and to adjust and improve injection-production balances,with added thickness of water displacement up to 61.8m and added developed reserves 16.1~104t.Therefore,development situations are improved for the main reservoir and secondary reservoirs,leading to adjustment of 40 wells,oil production increase of 3.1t/d and wa- ter cut decrease of 1.1%.The guidance to adjust water injections has mitigate contradictions among different reservoirs,and the guidance to modify single well productivity has resulted in oil production increase of 4419.2t accumulatively
