TX天然气藏上方和周边的综合化探异常特征 ,在一定程度上能反映其成气成油区段的位置。特别是以 CH4 、C2 H6、C3H8、ΔC指标在气田上方所具有的顶部晕和吸附相态Hg、Ks、Fe2 +元素指标在气田周边形成的半环状晕 ,二者形成的镶嵌结构。其镶嵌结构地段正好指示地下深部天然气田分布中心位置的特征 ,是天然气综合化探寻找天然气田重要的地球化学找矿标志和异常评价的判别依据 The abnormal characteristics of the integrated geochemical exploration above and around the TX natural gas reservoir can reflect the location of its gas-to-oil formation to a certain extent. In particular, the inlaid structures formed by the top halo and the Hg, Ks, Fe2 + elements of Hg, Ks, Fe2 + elements formed above the gas field with the CH4, C2 H6, C3H8 and ΔC indicators above the gas field form the mosaic structure. The inlaid structure shows the location of the distribution center of gas field in deep underground gas field, which is the basis of gas geochemical exploration to find important geochemical prospecting signs and anomalous evaluation of natural gas field
