摘　　要：阐述新场地区地质构造背景的同时,在油气水文地质和大量水化学分析测试数据基础上,研究了川西新场气田须二段地层水化学参数的基本特征,勾划了地层水化学参数化学场图,揭示了地层水化学分布规律性,并结合油气研究成果对新场地区含油气性和气田保存条件进行了水文地质评价和预测。对于相关的气田地层水渗流场、地下水成因、单井水产量预测以及储层改造工艺技术具有一定的指导意义。In this study,some aspects are involved:(1) the basic characteristics of chemical parameters of formation water in Xujiahe 2 Member,Xinchang gasfield in western Sichuan Basin,are studied based on geological structure setting of Xinchang area,oil and gas hydrogeology,and hydrogeochemical analysis and test data;(2) the hydrochemical field of chemical parameter for formation water is obtained;(3) the rule of chemical distribution for formation water is also explored;and(4) the hydrogeological assessment and prediction are conducted for this area.All results have certain guiding significance for the following studies: seepage field of formation water,groundwater origin,water-production prediction for a single well,and reservoir reconstruction technology.
