| Abstract: | Based on the analysis of rock slides,casting slides,scan electron microscope and X-ray diffraction etc,the characteristics of diagenetic evolution of clastic reservoirs in Shahejie formation at the northern part of west sag are studied.Three diagenetic stages in Shahejie Formation are divided as subphase A of early diagenesis,subphase B of late diagenesis and subphase A of middle diagenesis.Four types of diagenesis are recognized,including compaction,cementation,dissolution and fracturing.The compaction and cementation destroy the primary pore structure intensively,dissolution and fracturing change the pore structure effectively.The succession of diagenetic evolution is summed,five types of diagenetic facies are recognized,and the favorable diagenetic facies to the reservoir development are indicated. |
