The Chuandong Tieshangang Region Triassic Feixianguan Diagenesis And Reservoir Studies

Guided by carbonate sedimentology carbonate reservoir geology and diagenesis, Utilized with the methodology on combination of field and indoor ,macroscopic and microscopic. Based on normal observation of microsection, United with cathodeluminescence wrappage of mineral and isotope ,The paper makes a deep research on carbonate diagentic characteristics and reservoir characteristics, expoundes the diagenesis and its characteristics in diagenetic process in FeiXianGuan formation in detail, establishes buried solution mold and three dolomitization molds, divides diagenetic environment diagenetic stage testifies diagenetic evolution sequence of beach facies sediment and non-beach facies sediment, projects main reservoir porosity evolution mold, expounds the characteristics of reservoir lithology . the type of reservoir space characteristics of pore structrure and comments on different kind of reservoir , Studys the reservoir distribution and analyzes the controlling factors of reservoir development.Fracture-Pore reservoir takes up a big part in FeiXianGuan reservoir. The study indicates that the reservoir is controlled and influenced by sedimentary facies diagensis and structrure. So high grade reservoir mainly distributed in the south of Tieshan and in LongHuiChang structure on the platform beach ,which disperse in the upper of FeiXianGuan I and middle and bottom of FeiXianGuan II, in arrange.
