ABSTRACT
With the deepening of XJWZ fault tight conglomerate gas exploration, the Shahezi Formation shows great exploration potential. To strengthen the deep natural gas exploration in the northern Songliao Basin and undertake the prediction of the conglomerate reservoir in the Shahezi Formation, this paper studies the prediction of a well-to-seismic integration reservoir in the study area and predicts the favorable reservoir development area. We carry out sequence division and comparative interpretation of the Shahezi Formation on the basis of the whole XJWZ fracture tertiary sequence division scheme, and the characteristics of the wave group, to synthetic seismic records as a bridge, combined with logging, seismic profile characteristics, and accurately identify the three, four, and five sequence interfaces. Unidirectional well analysis, seismic phase analysis, and sedimentary phase analysis were conducted by combining core observation, logging data, and logging curve feature identification. The reservoir characteristics and physical distribution were also analyzed.
