There are extraordinary active thermal fluids in the mud diapir zone of central depression in Yinggehai basin. Great achievements have been attained presently o n the shallow natural gas exploration in mud diapir zone on the base of the regu larity of gas migration and accumulation controlled by the upward-intrusion of thermal fluid. So far the most GIP is discovered in the shallow exploration area . Changnan Block is one of the areas where are most active upward-intrusion of thermal fluids in the middle-south of the mud diapir zone. It has typical chara cters in seismic sections. In this article, the geophysical characters and uniqu e origin causes of the thermal fluids action are revealed by studing on the prof ile and the plane characters of the mud diapir-thermal fluid seismic smear zone geophysically.
