为了研究绥滨坳陷城子河组砂体输导天然气的能力，根据该砂体的发育程度(砂地比)和渗透率特征，定义和求取了砂体输导天然气能力评价参数，其值为0.01～4.25，高值区主要分布在坳陷东部，由此向西该评价参数值逐渐减少。通过定义求取气藏天然气聚集效率，对我国11个以砂体为主要输导通道的大中型气田天然气聚集效率值进行了计算，并通过对这11个大中型气田砂体输导能力评价参数与天然气聚集效率之间关系研究，得到绥滨坳陷城子河组高效、中效和低效砂体输导层输导天然气能力评价参数评价标准，据此评价标准得到城子河组砂体输导能力高效区位于坳陷东部，中、低效区位于坳陷西部。结合研究区圈闭条件综合研究认为，绥滨坳陷城子河组天然气有利区位于绥滨坳陷福兴斜坡。

To study the gas transporting ability of the sandbody of Chengzihe formation in the Suibin depression, a parameter evaluating the gas transporting ability through sandbody is defined and calculated according to the ratio of thickness between sand body and formation and the characteristics of permeability. The value range of the parameter for the Chengzihe formation is from 0.01 to 4.25. The high value area is located in the east of the Suibin depression, from which the parameter gradually decreases to the west. The gas accumulation efficiency of 11 largeand medium gas fields whose gas transporting pathway is sandbody is calculated through the definition. Based on the relationship between these 11 fields' gas accumulating efficiency and their evaluation parameters of gas transporting ability, an evaluation standard is established for determining high, middle or low efficiency of transporting ability. According to this standard, the high efficiency area is located in the east, and the middle and low efficiency areas are in the west of the Suibin depression. The study indicates that the favourable area for gas is located in the Fuxing slope in the east of Suibin depression.
