过去使用的不停钻测斜保护器(如图1),是连接在岩心管接手下面,随粗径钻具一起下降到需要测斜的位置,静止一段时间(40分钟)时,玻璃管内被侵蚀上痕迹为止,才正式钻进,待本回次进尺结束,在上升钻具时,取下保护器才可完成测斜任务.这种保护器有以下缺点:1、在上卸保护器时,麻烦、浪费时间,每次上下钻具时均需拧卸二次。2、经常拧卸,岩心管丝扣易磨损。3、保护器在岩心管接手下面,钻进时易被震动脱扣 The non-stop drilling protector (Figure 1) used in the past was connected below the core pipe to take down with the large-diameter drill to the position to be measured. When still for a period of time (40 minutes), the inside of the glass tube Erosion on the trail so far, before formally drilling, until the end of this footage into the end of drilling tools, remove the protector to complete the task of inclinometer.This protector has the following disadvantages: 1, when unloading protector , Trouble, a waste of time, every time up and down drilling tools need to unscrew twice. 2, often unscrew, core tube buckle easy to wear. 3, protector in the core tube to take over, easy to be vibration when drilling tripping
