摘　　要：通过西斜坡区萨二、三油层天然气西运输导通道构成及特征分析,可以得到天然气自齐家古龙凹陷向西斜坡区的侧向运移主要是通过断层沟通砂体来实现的。在砂体输导天然气能力影响因素分析的基础上,定义了天然气输导能力综合评价参数,并建立了一套研究方法。通过西斜坡区萨二、三油层天然气输导能力综合评价和其与油气分布关系研究可以得到,齐家凹陷至江桥地区及其附近,萨二、三油层天然气输导能力逐渐降低,若有适当的圈闭构造存在,有利于天然气的聚集成藏,是西斜坡区萨二、三油层天然气成藏与分布的有利地区。Through the analysis on the composition and characteristics of gas transporting pathway of S_(2+3) reservoirs in the west-slope region.It was considered the lateral migration gas from Qijia-Gulong sag to west-slope region is mainly implemented by sandbodies connected by faults.Based on the analysis of factors influencing gas transporting ability,comprehensive evaluation parameter of gas transporting ability was defined,a set of methods studying gas transporting ability are established.Through a comprehensive evaluation of gas transporting ability of S_(2+3) reservoirs and study of the correlation of oil and gas distribution in the west-slope region,it is considered that in Qijia-Gulong sag and areas around gas transporting ability of S_(2+3) reservoirs in west-slope region are gradually reduced,trap structures in this region are favorable areas of gas accumulation and distribution.
