| 摘 要： | 大牛地气田上古生界储层是典型的低孔低渗,从储层物性来看,盒3、盒2段最好,其次是山1段,较差的为山2、盒1段。造成上古生界主要储层物性差异的因素主要为沉积相、成岩作用、粘土矿物和裂缝等。沉积相是形成物性差异的基础,曲流河砂体物性最好,其次是辫状河砂体,而三角洲河道砂体最差;成岩作用是形成物性差异的重要因素,尤其是压实作用,从山1段至盒3段随着压实作用的减弱,储层剩余粒间孔隙增多,物性相对变好;粘土矿物成分、含量及裂缝对物性差异的形成有着不可忽视的作用,一般伊利石含量越高,物性越差;微裂缝越发育,物性越好。

| Abstract: | The Upper Paleozoic reservoirs in the Daniudi Gas Field are characterized by low porosity and low permeability.The physical property of the 3rd and 2nd members of Lower Shihezi Formation is the best,while that of the 1st member of Shanxi Formation is worse,and that of the 2nd member of Shanxi Formation and the 1st member of Lower Shihezi Formation is the worst.The difference of physical property is influenced by several factors such as sedimentary facies,diagenesis,clay mineral,fissure and so on.Sedimentary... |
