【摘要】 辽河油田茨 4 1断块储层砂体类型有冲积扇砂体、浊积岩砂体、分流河道砂体和河口坝砂体 ,它们经历了压实、石英和长石次生加大、碳酸盐胶结、溶蚀等成岩作用。物性分析表明 ,冲积扇砂体、浊积岩砂体储集性能较差 ,分流河道砂体和河口坝砂体的储集性能较好。渗透率、孔隙度在单个砂体内的变化规律复杂。但总的来看 ,河口坝砂体物性非均质性要比分流河道砂体小。更多还原

【Abstract】 The reservoir sandbodies in faulted block Ci 41 in Liaohe oilfield consists of sandbody from alluvial fan, turbidite, fluvial channel and mouth bar These sandbodies undergo various diagenesis such as compaction, overgrowth of quartz and feldspar, dissolution of feldspar,and carbonate cementing The physical analysis conducted shows that the porosity and permeability are rather low in sandbodies formed in alluvial fan and turbidite and rather high in sanbodies formed in fluvial channel and mouth bar The variation of porosity and permeability is complicated within a single sandbody In general heterogeneities of physical property in the sandbodies of mouth bar are less than in the channel sandbodies更多还原
