Genetic types and sedimentary model of sandbodies in a shallow-water delta:A case study of the first Member of Cretaceous Yaojia Formation in Qian'an area,south of Songliao Basin,NE China
Based on outcrop,core,logging and mud logging data,and modern deposition analog,the sandbodies genetic types and spatial distribution in different facies belts of the shallow water delta in the first Member of Cretaceous Yaojia Formation(K2y1) of Qian'an area in Changling sag of southern Songliao Basin were analyzed,and the sedimentary model of shallow water delta was established according to deposition process.Active channel sandbodies,point bar sandbodies and bifurcation bar sandbodies in distributary cha...
