锦150块中生界油层流动单元与剩余油分布规律研究
|
摘要
本文以辽河油田锦150块中生界油层为例,以Ⅱ油层组为研究对象,运用研究区地层和储层,沉积相及沉积微相特征,以及储层流动单元的划分方法,对研究区的孔渗特征、流动单元和剩余油分布进行深入的研究。锦150块中生界油层为冲积扇储层,具有低孔、渗的特点。为了锁定有利的剩余油富集区,运用流动分层指标(FZI)的方法结合聚类分析法对研究区Ⅱ油层组的12个小层进行流动单元划分,共划分3个流动单元。最后运用沉积微相与流动单元的研究成果对剩余油分布规律进行研究,确定A类流动单元主要分布主河道,剩余油饱和度相对较低;B类流动单元主要分布河道侧缘,剩余油饱和度高,分布最广,剩余油挖潜力最大;C类流动单元主要分布河道间,渗流能力差,剩余油饱和度低或近似零。
In this article, to the Mesozoic oil of the Liaohe oil-field Jin150-block as an example,Ⅱoil group to study, by the use of the study area formation and reservoir, the sedimentary facies and the sedimentary microfacies of the characteristics, and the reservoir flow units of the division method, has research the study area on the porosity and permeability characteristics of the flow unit and the distribution of remaining oil in-depth.The Mesozoic oil of Jin150-block is the alluvial fan reservoir, with low porosity and permeability characteristics.In order to lock in favorable remaining oil rich region, the study uses the targets stratification mobile (FZI) and the cluster analysis method ,to divived the flow units for the study areaⅡgroup oil of 12 small-for, divided into 3 flow units in all.Finally,the article the studies remaining oil distribution for useing the research results of sedimentary microfacies and the flow units , and determine to A-class flow units being mainly located in the river center, and residual oil saturation being relatively low; B-class flow units being mainly located in the side of the river edge, high residual oil saturation, the most widely distributed, the remaining oil potential of the largest dredging; C-class flow units being mainly located between river course, poor flow, low residual oil saturation or near zero.
