塔北沙雅隆起及邻区的中三叠统可划分出披覆构造型勘探层。在统计或估计其勘探目标数、油气藏体积参数、地层温压及油气物理性质变化规律基础上,应用勘探层法进行油气资源评价。结果表明,此勘探层油气资源丰富,勘探前景广阔。

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?10-3.9124?10T and 265.7?10-1453.0?10m.Favourable tar-gets for hydrocarbon exploration are the central and southern parts of Ackule-Harahatang area.
