摘　　要：作为定向钻进水平连通井组,须探明盐矿层顶板及其上下标志层的地层情况,以便与先期完钻的直井进行层位对比。该盐矿拟采用定向水平井连通法进行水溶开采,为提高定向水平井的“中靶”概率,采用精准定位技术实现一次“中靶”连通,使该井组迅速投入生产,确保了采区先期施工井组满足采输卤装置区的总产量要求。As a horizontal connected well group in directional drilling,it is necessary to find out the stratigraphic conditions of the salt deposit roof and its upper and lower marker layers,so as to compare with the vertical wells drilled earlier.The salt mine intends to adopt the directional horizontal well connectivity method for water solution mining.In order to improve the probability o“f hitting the target”of the directional horizontal well,the precision positioning technology is adopted to achieve a“hitting the target”connectivity,so that the well group can be put into production quickly and ensure that the pre-construction well group in the mining area can meet the total output requirements of the halogen production unit area.
