| Abstract: | In order to reveal the relationship between different diagenesis and pore evolution,the characteristics of diagenesis and pore evolution of He 8 reservoir in Well Block Su 14 were studied based on the laboratory results of physical property,cast section,SEM,X-ray diffraction and inclusions.The result shows that the lithology of He 8 reservoir is mainly coarse sandstone,middle to coarse quartz sandstone and lithic sandstone with subangular psephcity,middle sorting,high compositional maturity and low textural maturity.Compaction,pressure solution,cementation and dissolution are the main diagenesis.The diagenesis in this area has entered into the B period of late diagenetic stage.The analysis of pore evolution model shows that the initial porosity is 35.7%,9.71% porosity is lost due to the early stage compaction,the cementation at early and late stage causes 23.52% porosity to loss,but the dissolution at late stage adds 6.34% porosity.The different diagenesis has common effect on porosity,which leads to the characteristics of low porosity and low permeability in studied area. |
