Abstract

Yitong Basin is a narrow Cenozoic faulted basin of Tanlu fault zone, in which Sheling Formation in Botai Sag has great exploration potential. Limited by complex geological conditions, unclear reservoir forming control factors and unknown exploration direction, the exploration process is restricted. By utilizing drilling, logging, and seismic data, and through the restoration of ancient landforms, the distribution of underwater fans near the coast of the Botai Depression was finely characterized. Combined with the structural characteristics of the southeastern margin, a favorable reservoir formation model for the northwestern margin of the Botai Depression was conceptualized and established. There are three inshore subaqueous fan bodies in the northwest margin of Botai depression, and two large nose-like structures in the Soudengzhan structural belt in the southeast margin. The two structures are well configured and which can form lithologic structural traps. The southeast margin of the traps is controlled by the pinch-out line of sand bodies and the northwest margin is controlled by the structure. The concept of establishing a favorable reservoir formation model for the nearshore underwater fan of a narrow and long graben style fault basin has expanded the favorable exploration field of the Botai Depression.
