尕斯库勒E31油藏沉积微相及其对剩余油分布的影响

沉积微相是控制储层物性好坏的根本因素,不同成因类型的储层具有不同的物性特征,因而直接影响了流体的分布和流动特征。尕斯库勒油田E31油藏的开发已进入中高含水期,因而研究剩余油分布规律显得极为重要。通过对储层沉积成因的分析并结合油田的开发动态资料对整个油藏的4个油组共22个小层沉积微相及剩余油储量进行分析统计,找出剩余油富集的层位及有利相带,尤其是高剩余油储量丰度所处的位置,为油田的开发挖潜提供重要信息。

The sedimentary microfacies of Gasikule Oilfieid E31 oil reservoir and its affect on distribution of residual oil

Sedimentary microfacies is fundamental factor which control reservoir nature,different genetic type reservoir bed have different characteristic,so it affect fliud body's distribution and flow feature.Gasikule Oilfield E31 oil reservoir has gone into medium-high water-containing developing,so it is important to study distribution of residual oil.The correlation of performance date and reservoir bed genesis to analyze 22 substrates of I~IV reservoir rocks.Searching for enrichment place and microfacies,especially,high abundance place,offer to important message for the further development of later remanent oil.
