Study on the characteristics of Jurassic reservoir diagenesis and hydrocarbon filling in middle 4 block of Jungar Basin
摘要
Abstract
In order to define the regularity of hydrocarbon accunulation of Jurassic reservoirs in Middle 4 area of Jungar Basin,by the methods of core description,thin section observation,SEM,grain size analysis,temperature measurement of inclusions and other methods,combined with the burial history and thermal history,analyze the petrological characteristics,diagenesis and hydrocarbon filling characteristics.The results show that the major rock type of the Jurassic reservoir lithology in the study area is dominated by feldspathic fithic sandstone,which has experienced complex diagenesis process,and experienced three stages of hydrocarbon filling.In addition,the coupling relationship between hydrocarbon filling and diagenesis is analyzed.The Toutun River formation has experienced favorable hydrocarbon filling process,has great exploration potential,and can be the later exploration direction.关键词
