中文摘要:

      通过对达州 -宣汉地区双石庙背斜构造特征、深部断裂、储层裂隙等因素综合分析，采用空压机方式对柳 1井开展了抽水试验，计算了水文地质参数，并估算了单井影响范围内资源量；结果表明双石庙构造三叠系卤水储层富水性弱，单井影响范围有限，资源量为 855 × 104 m3，该结果将为后续探(采)矿权设置、开发井的布设提供依据。

英文摘要:

      In this study, the structural characteristics, deep faults, reservoir fractures and other factors of Shuangshimiao anti.cline in Dazhou Xuanhan area were comprehensively analyzed. The pumping test of well Liu 1 was carried out by using air com.pressor, the hydrogeological parameters were calculated, and the resources within the influence range of single well were esti.mated. The results show that the water yield of Triassic brine reservoir in Shuangshimiao structure is weak, the influence rangeof single well is limited, and the resources are 855×104m3, which will provide basis for subsequent exploration (mining) right setting and development well layout.
