二类油层发育具有“低、薄、窄、差”的特点,注聚开发过程中井组间见效差异大,开发效果难以保证,为此开展井组分类挖潜方法研究,探索二类油层聚驱高效开发的有效途径。本文通过分析南二西区块动静态数据,确定井组分类评价因素,利用数理统计分析和模糊数学方法建立多因素综合评价体系,确定井组分类评价标准及方法,对二类油层井组进行分类,并根据不同井组开发矛盾,开展分类针对性治理,取得了较好的开发效果。
The development of the second type reservoirs has the characteristics of low, thin, narrow and poor. During the process of polymer injection and development, there are great differences between the wells and the development results are difficult to guarantee. Therefore, Drive efficient development of effective ways. In this paper, by analyzing the dynamic and static data of South Second West Block, determining the factors of well group classification evaluation, using mathematical statistics and fuzzy mathematics to establish the multi-factor comprehensive evaluation system, determining well group classification criteria and methods, classifying the second group of well groups According to the contradictions in the development of different well groups, the project carried out targeted management and achieved good development results.
