双河岩盐矿区的钻探工程发现，该区岩盐层厚度变化急剧，并且埋藏浅者厚度大，表明有沉积期后改造过程，或称“盐运动构造”。经大地电磁测深和高精度重力测量，进一步发现在岩盐层上方和下方各有一个“泥辟构造”存在。重力异常还显示出岩盐层厚度向两侧根快变薄、尖灭的特点。文章综合钻探、物探研究成果，对岩盐层富集区进行了圈定。 The drilling project in Shuangheyan salt mining area found that the thickness of the rock salt layer in this area changed rapidly and the thickness of the buried shallow area was large, indicating that there was a post-depositional reforming process, or “salt movement structure.” It is further found by geomagnetic sounding and high-precision gravimetry that there is a “mud-tectonic structure” above and below the rock salt layer. Gravity anomalies also show that the thickness of rock salt layer on both sides of the rapid thinning, pinch off features. The article comprehensive drilling, geophysical research results, the rock salt enrichment area were delineated.
