深层卤水自喷钻井若干特征的分析

ANALYSIS OF SOME FEATURES OF THE FLOWING WELLS WITH DEEP BRINE

本文以四川盆地中部的L_1井为例,讨论深层卤水自喷钻井卤水产出特征、水文地球化学特征和开采动态特征,并对钻井的测试资料进行分析,预测该钻井的卤水可采资源量。

Deep brines in the Sichuan Basin are deep-seated and have high total dissolved solids. The hydralic heads of brine-bearing aquifers are so high that after the drilled wells are exposed, the aquifers can pour brine out of the land surface.It is important to study the brine-flowing wells which are of great exploitable significance. Taking the well Li in the central basin as an example, this paper discussed some features of occurrence, hydrochemistry and the exploitation behaviour of the deep formation brine. The test data are analysed and the recoverable brine resources of the well are also evaluated.
