勘查区地处鄂尔多斯盆地中东部古隆起东侧陕北斜坡的米脂坳陷北缘，是近年来正在开发的一个井矿盐田。采区含盐地层赋存于奥陶系下统马家沟组第五段，自上而下划分10个亚段，其中八亚段和十亚段为主要含盐地层。采区3个取心直井的试验及化验资料分析表明，采区盐层在垂直剖面上各项实验数据没有明显的变化规律，故采用平均统计方法对各盐层进行了分析。这些分析数据可为该采区盐井的合理开发提供了技术参数，进而对陕北其它盐田的大开发提供了科学借鉴。%The Jinjie exploration area is situated on the north margin of Mizhi depression, northern Shaanxi clinoform zone, and east side of the Ordos Basin middle-eastern paleouplift, a newly exploited well salt field. The salt-bearing strata belong to Ordovician Xiamajia-gou Formation fifth member, 10 sub-members can be divided from top to bottom, and sub-members No.8 and 10 are main salt-bearing strata. The testing and analysis data from samples of 3 coring vertical wells have shown that all tested data of salt layers have no regula-tion on vertical section, so using the statistical average method to analyze salt layers. The analyzed data can provide technical parameters for rational exploitation of salt wells in the area, and then provide reference to large-scale development of other northern Shaanxi salt fields.
