3 ) the sandbody distribution , physical properties , pore structure and heterogeneities are affected by the microfacies . at the center part of underwater distributive river course , the petrophysics and physical properties are both better than that at the edge of the microface . 4 ) the chang 61 2 - 3 substrata and the substrata of chang 62 " member which show the better porosity , permeability , and better pore structure ; display lower permeability variation coefficient , dart - coefficient and contrast - coefficient and good connecting sandbody so the horizontal heterogeneities is weaker ; whereas manifest stronger inner - heterogeneities due to the numerous intermediates ; present stronger inter - heterogeneities caused by the greater frequency of sandbody 长6储层中长6 _ 2 ~ ( 1 - 3 )和长6 _ 2 ~ 1砂层中的各个小层的孔隙度、渗透率值、含油性较好;平面非均质性较弱,表现为级差、突进系数、变异系数较低且砂体的连片程度高,钻遇率和连通系数较高;与此同时,层内非均质性较强,表现为垂向上夹层的数目较多,厚度较大;层间非均质性也较强表现为分层系数较高。
