摘　　要：通过对新场气田地气测量分析,发现地气测量的纳米微粒金属元素在新场气田上方有明显的异常显示。综合土壤地球化探结果对比分析,认为Ba、Cd、Cu、Mo、Zn、P、V、Ni等20多种纳米微粒金属元素在新场气田与相同的土壤微量元素都有着共同的响应。同时分析了有机地球化学指标在气田地表上方的表现模式,其特征和地气、土壤元素表现基本一致。地气测量方法在一定条件下对寻找天然气藏、确定气田范围具有一定的应用前景。Geogas survey performed in the Xinchang gas field shows that there exist obvious anomalies of nano - particle metal elements over the gas field. A comparative analysis of integrated soil geochemical exploration reveals that more than twenty nano - particle metal elements such as Ba, Cd, Cu, Mo, Zn, P, V and Ni have common response over the Xinchang gas field and in soil. Characteristics of organic geochemical indices over the Xinchang gas field are basically identical with those in geogas and in soil. Under certain conditions, geogas survey is somewhat promising in the prospecting for natural gas accumulation and the delineation of gas field.
