摘要
目前岩盐矿开采几乎都采用水平井对接连通工艺技术,即应用定向技术使水平井与目标直井对接连通,实现井组直接连通采卤生产。在水平井实施过程中,控制水平段井眼轨迹在盐层中的位置是十分重要的;当水平段井眼轨迹在盐层的中或上部时,则不能充分开采岩盐矿,井组的采卤流量和浓度也会不理想;因此应尽可能让水平段井眼轨迹位于盐层的下部,在单盐层矿区和地质条件复杂矿区则尤为重要。
At present, almost of the salt mine exploitation takes horizontal well docking connectivity technology which is usingdirectional technology to have the horizontal well and the target well docking connected and realize well group connect directly. In theconstruction of the horizontal well, it is quite important to control the position of well trajectory of horizontal segment. When the welltrajectory of the horizontal segment is in the middle or the upper of the salt layer, the salt mine cannot be fully exploited and the flowand the concentration of the brine is not ideal either. So we should as far as possible to make the well trajectory in the lower part ofthe salt layer,which is more important in the single salt layer mine area and the geological condition complex mine area.
