Middle Triassic in Shaya Uplift and the adjacent area is one of important exploration targets.Based on the analysis of hydrocarbon-bearing condition

a Middle Triassic drape structural play was identified by adopting play-analysis method.In the calculation and es-timation of hydrocarbon-bearing probability of exploration play and exploration prospect

the parameters of oil-gas pools

the number of drillable prospects as well as functional re-lationship of five geological variations

the above mentioned data and functional relation-ship were inputted in FASPUM.The result suggests that the play shows wonderful prospects in hydrocarbon exploration

and the amounts of recoverable resources are re-spectively 0.82543?10

.Favourable tar-gets for hydrocarbon exploration are the central and southern parts of Ackule-Harahatang area.
