摘要

通过对鄂尔多斯盆地油房庄油田定31井区长1油层组进行沉积分层,并依据岩石物理特征参数,采用直接聚类分析的方法,将该区长1油层组划分为A、B、C、D四类流动单元并对其地质意义进行了分析。研究结果表明,A类流动单元渗流能力和储集能力强,采出程度高,剩余油饱和度低;B类流动单元渗流能力和储集能力较强,采出程度较高,为研究区主要的生产层系;C类流动单元渗流能力和储集能力一般,采出程度较低,剩余油饱和度相对较高;D类流动单元渗流能力和储集能力差,为非产层。

Abstract

Through the deposition layering of Chang 1 reservior in Ding 31 wel l area of Youfangzhuang oil field,in terms of the character parameter of rock ph ysics,adopted the method of direct clustering analysis, A, B, C, D four kinds of  flow units are classified in Chang 1 reservior of this area, and the geological  meaning of them are. analysised. Study results show,type A has strong percolati ng and storing ability, high picking degree, low saturation degree of residual o il; type B has rather strong percolating and storing ability,rather high picking  degree, it's the main productive formation of research area; type C has commonl y percolating and storing ability, rather low picking degree, comparatively high  saturation degree of residual oil; type D has poor percolating and storing abil ity, is a non-produce formation,poor effect of expoitation.
