The Comparative Analysis Of Diagenesis Of Outcrop Sandstones And Core Sandstones In Chengzihe Formation,Muling Formation, Jixi Basin

Jixi Basin is one of the important coal-bearing Basin,locating the sourth-east of Hei Long Jiang province. Exploring proving,Some oil-gas exploring cores and coalfield exploring cores have been seen different degree oil-gas showing in Jixi Basin,Chengzihe Formation and Muling formation are the mostly coal-bearing formation and reservoir, The capability of sandstone reservoir is bad ,characteristic of low-hole and low-seep thin throat kind of reservoir. The purpose of paper is to describe the petrology character of outcrop sandstones and core sandstones and judge their roke type, compare the similarities and differences of autogenetic mineral,, diagenesis types, intergrowth sequence, diagenetic facies, diagenetic phase of outcrop sandstones and core sandstones, provide academic precondition condition for studying better reservoir in studied region.The techniques applied in this study include thin-section identification Scanning Electro Microscope (SEM) obsevation, X radial-diffract analysis, stained-thin section observing,The samples of outcrop sandstones and core sandstones in studied region come from Chengzihe Formation and Muling formation contain coal and reservoir,Jixi Basin.Though stating sandstone thin-section's clastic constituents of outcrop sandstones and core sandstones,collecting sandstones' clastic constituents datas from Jicanl core, Ji3 core, XijiD2 core and JiD6 core,it's judged to the roke type...
