本文应用“凹陷与圈闭资源评价专家系统”对松辽南泉头组、登娄库组所属58个主要圈闭,进行含气性评价.其中评为有利含气性圈闭20个.这些有利圈闭具备优越的成藏地质条件,有些圈闭经过钻探已获工业气(油)流或显示.说明该技术具有较高的可信度,这些圈闭可选为今后松南地区天然气勘探的重要目标.

In this paper,the resource evaluation expert system of depressions and traps is used to evaluate the gas-bearing possibility of 58 major traps in the Quantou Formation and Denglou Formation of the South Songliao Basin.Among them,twenty are regarded as favourable gas-bearing traps.These favourable traps have advantageous pool-generation geological conditions.After drilling,some traps have obtained industrial gas/oil or shows.It is indicated that this evaluation technology has higher reliability.So these traps can be selected as major targets for the natural gas exploration of the South Songliao area in the future.
