By studying , the paper brought forward the concept of dynamic geochemical belts , and indicated that the high pressure gas bearing structures distributed in the areas of hydraulic pressure forming belts , the gas fields , such as zhongba , pingluoba , hexingchang and bajiaochang , distributed mainly in the discharge and stabilization belts , guankou - pingluoba and daxing nose are the most promising prospects , and laoguanmiao - jiulongshan , xiaoquan - fenggu and wenjiang - shifang are the favorite ones 4 、川西坳陷侏罗?白垩系、须二段和须四下段分属三个独立的含水系统。首次提出地下水地球化学动力带的概念,并系统研究了其分带特征。指出高压含气构造主要分布在水压形成带;中坝、平落坝、合兴场、八角场等气田处于稳压带和卸压带。
