摘　　要：双河横江地区位于四川盆地边缘。区域内存在两个与地层有关的地球化学背景场，烃类指标与△Ｃ、Ｈｇ、Ｆｅ２＋等非烃指标异常间具有明显不同的配套组合关系。各指标综合化探异常特征和指标间组合关系对测区油气分布、保存情况进行评价，指出两处属构造泄漏泄压区及四个有利远景区，评价结果为下一步钻探部署具有指导意义。Shuanghe-Hengjiang district locates around the boundary of Sichuan Basin, two geochemical background fields, related to the strata, exist in this district, in which anomalies of hydrocarbon indices and △C,Hg,Fe 2+ indices display obvious different combination relations. According to the comprehensive geochemical prospection anomaly and the anomaly combination, evaluation is made on the oil gas distribution storage. Two structural pressure relieving area and four potential area are pointed out, which is useful for guiding the future prospecting of oil gas
