摘　　要：随着采卤井开采时间的增加,井下开采盐层横向溶腔不断扩大、纵向溶采高度逐渐上升,导致井下套管脱落或损坏,生产出卤量减少。为了保证盐矿正常采卤生产,通常采用机械修井方法,使盐卤生产井重燃生命活力。在修井前,为了充分掌握井内盐层、地层、套管、盐溶腔高度等信息,为机械修井方案提供可靠的基础资料,选择有效的探测方法能达到事半功倍的效果。With the increase of mining time,the horizontal solution cavity of underground mining salt layer expands and the vertical solution mining height rises gradually,which leads to the casing falling off or damage and the production of brine decreases.In order to ensure normal brine mining,mechanical workover method is usually adopted to rekindle the vitality of brine production Wells.Before workover,in order to fully grasp the salt layer,formation,casing,salt cavity height and other information in the well,to provide reliable basic information for the mechanical workover program,the selection of effective detection method can achieve twice the result with half the effort.
