摘要
本文在分析大庆喇、萨、杏油田1964年以来所钻取的51口密闭取心井400多个油层分析资料的基础上,提出了大庆油田萨、葡油层纵向上4种主要非均质类型,探讨了各类油层的水洗特点、水驱效果及其影响因素,并对不同开发地区水驱开采效果作出了初步评价;同时,分析了油田高含水后期各类油层的剩余油类型及其分布,为油田后期开发调整指出了主要对象和挖潜方向。
<ABSTRACT> Based on the analysis of more than 400 reservoirs in 51 sealed
core drilling wells drilled from 1964 in Lamadian, Saertu and Xingshu gang
oilfields of Daqing area, this paper introduces four main types of
heterogeneties, discusses the water-flushed property, waterflooding efficiency
and effecting factors of every reservoir and preliminarily evaluates the
water displacement efficiency of different development areas. At last, the
residual oil types and their distribution at the later period of high water cut
stage in every type of reservoir are analyzed and main objectives of adjus-
tment are put forward for further development.
