摘要(Abstract)：

为了研究绥滨坳陷东荣组砂体输导天然气的能力,根据砂体的发育程度(砂地比)和渗透率特征,定义、求取了砂体输导天然气能力评价参数。得到绥滨坳陷东荣组砂体输导天然气能力评价参数值为0.01~0.21,高值区主要分布在坳陷东部,由此向西砂体输导天然气能力评价参数值逐渐减少。通过定义求取气藏天然气聚集效率,对中国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。通过中国11个以砂体为主要输导通道的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,得到绥滨坳陷东荣组高效、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,据此评价标准可以得出东荣组砂体输导能力中效区位于坳陷东部,低效区位于坳陷西部。结合研究区圈闭条件,综合研究得到绥滨坳陷东荣组天然气较有利区位于绥滨坳陷福兴斜坡及东部斜坡带的东南部。
In order to study gas transporting ability through sandbody of Dongrong Formation in Suibin Depression,a parameter to evaluate gas transporting ability of the sandbody is defined and calculated according to the ratio of sandbody thickness and formation thickness and the characteristics of permeability.The evaluation parameter obtained for the sandbody in Dongrong Formation of Suibin Depression is from 0.01 to 0.21.The high value area is located in the east of the depression,and from the east to the west the parameter decreases gradually.The gas accumulation efficiency of 11 large and medium gas fields,of which the main gas transporting pathway is sandbody,is calculated.Based the study on the relation between gas accumulation efficiency and evaluation parameter of gas transporting ability through sandbody of these 11 gas fields,the evaluation standard to determine high,middle or low efficiency of Dongrong Formation in Suibin Depression is ascertained.According to this standard,it can be got that middle efficiency area is located in the east,and low efficiency area is located in the west of Dongrong Formation in Suibin Depression.With the consideration of the sealing condition of the studied area,it is thought that the more favorable area is located in Fuxing slope and the southeast of east slope in Suibin Depression.
