Sedimentary Characteristics and Sedimentary Model of Glutenite Fans in Shahejie Formation, Luojia area

        

        Glutenite Fans is one of the most favorable reservoirs for exploration and development in recent years and is widely distributed in the world. In recent years, major breakthroughs have been made in oil and gas exploration of glutenite fans in Luojia area in Luoxie 180 and Luo25 Wells. The Jiyang exploration area is a high mature exploration area in the east, which has entered the exploration stage mainly to search for subtle oil and gas reservoirs, and Glutenite Fans, as an important part of subtle oil and gas reservoirs, has become the most realistic and valuable exploration target at present.

       The Luojia area has a complex structural background, with the development of fault structures in the area, and the development of two sets of glutenite fans bodies of different origin, and the lithology difference is great. The diagenesis is complex and the calcareous intercalation is widely developed, which is of great significance for reservoir reconstruction.

        This paper takes the sand conglomerate of Es3 and Es4 members in Luojia area of Zhanhua Depression as the research object, synthesizes seismic, logging, core, analysis and test data, and carries out the research on the genetic types, sedimentary characteristics and diagenesis of the sand conglomerate controlled by different tectonic activities and provenance.
