摘要
根据四川盆地两个天然气藏的土壤地球化学异常特征、指标间的组合关系，建立了“环中顶”和“面状”化探异常模式。经川西地区油气化探生产实践，表明两种异常模式对寻找天然气田（藏）具有良好的效果。
Geochemical anomaly models of “Top in ring”and “Plane shape”have been setted up from the anomaly characteristics and association relationship between indices of soil geochemistry over two natural gas occurrences in the Sicuan basin.The two types of anomaly models for prospecting the natural gas field or occurrence have been proved to be effective by the producting practice of oil-gas geochemical exploration in the western Sicuan area.
