中文摘要:

      四川盆地三叠系地下卤水分布广泛，品质优良，是我国开采利用最早，工业价值最高的卤水资源。研究表明，地下卤水储层为低孔隙低渗透致密岩石，不利于卤水的运聚，而后期构造形成的断裂和裂缝控制了卤水的富集作用。

英文摘要:

      Ground brine of Trias is widely distributed in Sichuan Basin,Which has fine quality and fantastic industrial values.It is the earliest exploited brine resource of our country.Research has indicated that the storage lager of the brine is mainly of compact rocks with low prosity and poor permeability,which is unfavorable for the movement and gathering of the brine.However,ruptures and fissures in the lately formed bedrock structure determine the enrichment of the brine.\;
