摘要
华池油田华152区块长33储层从正式注水开发以来,整体表现受效不均,综合含水上升快,产量下降较快;单井含水差异很大,部分井水淹,采液、采油指数下降明显。为了研究剩余油分布,提高开采效果,提出合理的剩余油挖潜措施,利用数值模拟技术在该区块进行模拟工作,对已实施的措施进行评价,对新的挖潜措施进行预测分析。结果表明:华152区块生产井转注,其采收率和产能都有较大提高,重复压裂亦对产能贡献较大。
Reservoir Chang 33 of Block Hua152 in Huachi oilfield presented non-uniform response of injection,water cut ascended and production rate declined rapidly,single well water cut varied widely, parts of wells even watered out,fluid productivity index and oil productivity index declined obviously. In order to research the distribution of remaining oil and improve the recovery,numerical simulation was adopted to evaluate the implementary measures,and forecast the new development measures. The converted water injection well treatment for Block Hua152 remarkably enhanced oil recovery and productive capacity. The productive capacity was also increased by refracturing.
