便捷式SPT-1500型拖车钻机的研制与应用

Development and Application of Convenient SPT-1500 Trailer Mounted Rig

摘要:

拖车钻机具有搬迁转场方便快捷、钻机调平起塔操作简单、可大幅缩短辅助时间等优点，在水井、盐井等施工中得到较广泛的应用。针对原有的拖车钻机存在的问题，研制了便捷式SPT-1500型拖车钻机。该钻机采用可伸缩钻塔解决了原有钻机两节式钻塔现场安装不方便、花费时间长的问题；可移动的天轮组解决了双卷扬提吊时的滑车对中问题，提高了工作效率，使拖车钻机真正实现搬迁转场方便快捷，省时省力，可大幅缩短辅助时间。介绍了该钻机的结构特点及工作原理，重点阐述了其创新点。

Abstract:

Trailer mounted drilling equipments are widely used in water well and salt well construction due to its advantages of being convenient for rig relocation, easy for leveling and towering up operation with greatly shortened auxiliary time. Aiming at some problems of original trailer mounted rig, convenient SPT-1500 trailer mounted rig was developed. The difficulties of installation of two stage derrick was improved by extensible derrick, pulley position control was solved by mobile head sheave while double hoisting lifting. The paper introduces this rig about its structural features and the working principle with emphasis on its innovation points.
