新型SPT-1500拖车钻机的研制及应用

Development of SPT-1500 Trailer-rig and the Application

摘要:

为了实现水文水井施工优质、高效、快速的要求，满足中深井对钻机能力的要求，研制了SPT-1500型拖车钻机。该钻机是拖车、转盘式、正反循环钻机，主要由拖车架、动力系统、钻机、转盘、液压系统、气路系统、钻塔、钻具系统等部分组成。试验及应用表明， SPT-1500型拖车钻机结构简单、安装方便、转场快捷、性能稳定可靠，可满足1500 m深水文水井的钻井能力，并能适应各种地层的钻井要求。

Abstract:

In order to meet the high quality, high efficiency and high speed in hydrological well construction, the SPT-1500 trailer-rig is designed, which is a rotary rig with direct and reverse circulation, mainly consists of the trailer frame, power systems, drill, rotary table, hydraulic system, pneumatic system, derrick and drilling system, etc. The test and application show that SPT-1500 trailer-rig has advantages of simple structure, easy installation, rapid transition and steady performance; it has drilling capability to deal with the hydrological well of 1500m in depth and can meet the requirements of various stratum drilling.
