中文摘要:
      四川盆地海相三叠系嘉陵江组-雷口坡组(T1j-T2L)气田地层水按其构造开启程度,埋藏深度及水化学特征的不同,可划分出沉积变质水和渗入淋滤水两种基本成因类型,分属两种性质迥然不同的水动力系统,各自依据地静压力和静水压力由高压区向低压驱动的水动力条件,控制了盆地海相三叠系气田地层水资源及气藏的保存和分布。
英文摘要:
      In terms of the differences in the degree of opening the structures, the depth of the burial and the hydro-chemical characteristics between the gas field in-place water of Jialinjiang group and Leikoupuo group in the Sichuan Basin, the water can be classified as two basic formation types. The types are sedimentary degenerative water and permeating leach water, which belong to two quite different hydrodynamic systems. The hydrodynamic systems control the distribution and storage of the gas field in-place water and gas resources in the Trias marine bed of the Sichuan Basin,according to the conditions that the driving force is from high pressure zone to low pressure zone.
