摘要
Feixianguan Formation and Changxing Formation are the main target zones of Puguang Gas Field.The gas reservoir is buried deeply,the gas-bearing interval is long and the surface and underground condition is complex,which causes some difficulties for structure interpretation.In order to improve the accuracy of structure interpretation for the gas reservoir,this paper emphatically studies on the seismic horizon determination and tracking,fault combination and variable-velocity mapping,makes real-time tracking and analyzes the new drilling data by making use full of seismic data,log data,coring data and the 3D seismic man-machine league technology based on the fine stratigraphic correlation and following the interpretation principle from large to littile,from shallow to deep,from rough to subtle.The accuracy of structure interpretation is raised and a complete set of comprehensive structure interpretation techniques for deep gas reservoir are gradually formed.From the results of the study,the structural features of deep gas reservoir in Puguang Gas Field is more accurately recognized,which provides reliable geological basis for development well placement.
