鄂尔多斯盆地某油区延10储层非均质性特征分析摘要：储层非均质性研究是油气田勘探与开发地质研究中的重要基础工作，沉积微相、断层、流体性质及夹层等各种地质因素综合表现出油藏内部的储层非均质性,影响地下油水的运动规律,控制着剩余油的分布。本文针对研究区延10储层的区域地质背景、沉积条件和储层岩层特征,应用现代石油地质学、储层地质学、油层物理学、地球物理测井等理论为指导,分别从微观、层间、层内、平面4个方面分析了延10储层主要小层的非均质性特征,得出研究区延10段储层的整体非均质性较强。关键词：延10储层；微观非均质性；宏观非均质性TheanalysisofYan10reservoirheterogeneityincertainoilfieldinOrdosbasinAbstract：Studyofreservoirheterogeneityisimportantbasisinthestudyofoilandgasfieldexplorationanddevelopmentofgeologicalwork,sedimentarymicrofacies,fault,fluidpropertiesandsandwichvariousgeologicalfactorssuchascomprehensiveshowreservoirheterogeneitywithinthereservoir,affectthemovementofundergroundwater,controllingtheremainingoildistribution,thestudyoftheexplorationdeploymentandadjustmentofoilfieldinjection-productionwellspacing,extractandimproverecoverycanprovidescientificbasisforeffectively.Yan10reservoirinthestudyarea,theauthorofthispapertheregionalgeologicalbackground,sedimentaryconditionsandreservoirrockcharacteristics,applicationofmodernpetroleumgeology,reservoirgeology,reservoirphysics,geophysicalwellloggingtheoryastheinstruction,frommicro,layer,interlayerandplaneinfouraspectsanalysisYan10reservoirheterogeneitycharacteristicsofthreesmalllayers,itisconcludedthatthestudyareaYan10sectionofreservoirheterogeneitystrongerasawhole.Keywords:Yan10reservoir;Microscopicheterogeneity;Macroscopicheterogeneity目录TOC\o"1-4"\h\z\uHYPERLINK\l"_Toc389983120"绪论PAGEREF_Toc389983120\h1HYPERLINK\l"_Toc389983121"1地理地质概况PAGEREF_Toc389983121\h1HYPERLINK\l"_Toc389983122"1.1区域沉积背景PAGEREF_Toc389983122\h1HYPERLINK\l"_Toc389983123"1.2区域构造特征PAGEREF_Toc389983123\h2HYPERLINK\l"_Toc389983124"2储层非均质特征PAGEREF_Toc389983124\h2HYPERLINK\l"_Toc389983125"2.1微观非均质性描述PAGEREF_Toc389983125\h3HYPERLINK\l"_Toc389983126"2.1.1延10储层岩石学特征PAGEREF_Toc389983126\h3HYPERLINK\l"_Toc389983127"2.1.2主要油层组的岩性和电性特征PAGEREF_Toc389983127\h3HYPERLINK\l"_Toc389983128"2.1.3孔隙结构特征PAGEREF_Toc389983128\h3HYPERL
