| 摘 要： | 塔河油田勘探表明,上奥陶统良里塔格组是潜在勘探层位.通过岩心、测井、薄片、物性、钻井和生产测试等资料综合分析,认为良里塔格组具两套岩性组合,顶部和底部为浅水高能沉积,中间为深水低能沉积,物性比中下奥陶统差,渗透率非均质性较强,主要受泥质条带和裂缝影响.储集空间主要包括溶蚀孔隙、溶蚀孔洞和裂缝3类.储层类型有孔隙-裂缝型和孔洞-裂缝型两类,后者是主要储层类型.储集空间形成主要受同生期和表生期岩溶作用、埋藏溶蚀作用和断裂作用4个因素控制,其中断裂作用是良里塔格组储层形成和分布的主控因素.

| Abstract: | The exploration situations of Tahe oilfield indicated that the Lianglitage Formation(O3l) of the Upper Ordovician are the potential exploration layer.At present,the understanding of reservoir characteristics and control factors are still low,that are restricted the exploration and development in O3l Formation.Pass the comprehensive analyses of bore cores,well loggings,thin sections,petrophysical property,well and testing datum,the O3l Formation have two lithologic associations,the Upper and Lower are the sh... |
