Title: Reservoir Diagenesis of Lower Jurassic in Lenghu Area
Abstract: Based on the data of lithologic analysis and microscopic examination,the characteristics are studied,which include lithology,diagenesis type, pore type,clay mineral distribution and stage of diagenesis of clastic reservoirs in Lower Jurassic on the north margin of Lenghu area in Qaidam Basin.It is considered that a destructive diagenesis has a compacted pressure solution,consolidation and packing effect,while constructive diagenesis has the effect of solutions and breakdown,which is the major reason of fracture formation.Based on the analysis of the distribution and the order of authigenic minerals in the clastic rocks,the combination of clay minerals and interstratified ratio,Ro and colour of sporopollen,in combination with the structure and pore types of rocks,it is considered that the diagenesis of Lower Jurassic clasitc rock is strong,and it is at the late stage of diagenesis.
