摘　　要：L型水平井是煤层气开发的主力井型,目前国内煤层气L型水平井施工设备均为标准石油钻机,但石油钻机设备配置和安迁移运成本较高。而水源钻机购置成本低,且很多地勘单位原来都配备有水源钻机。为此,本文在研究总结常规水源钻机、石油钻机的设备原理、主要参数、差别特点的基础上,对TSJ-3000型水源钻机进行了4项改进设计,以达到标准石油钻机性能。同时,结合煤层气水平井地质条件、作业环境、施工工艺等特点,对改进TSJ-3000型水源钻机进行了4项提升设计,对随钻录井装置、液压大钳、潜水排污设备、气动绞车等进行改进,以满足煤层气L型水平井施工要求。应用改进TSJ-3000型水源钻机有效提高了钻完井工作效率和经济效益。The L‑type horizontal well is the main type of coalbed methane development.At present,the construction equipment of the L‑type horizontal well of coalbed methane in China are all standard oil rigs,but the equipment configuration and transportation cost of the oil rigs are higher.The water source drilling rig purchase cost is lower,farther many geological prospecting units are originally equipped with the water source drilling rig.Therefore,on the basis of studying and summarizing the equipment principle,main parameters and difference characteristics of conventional water source drilling rigs and oil drilling rigs,this paper has carried out 4 improved designs for TSJ-3000 water source drilling rig,to achieve standard oil rig performance.At the same time,according to the geological condition,working environment and construction technology of coalbed methane horizontal well,4 lifting designs for improving TSJ-3000 water source drilling rig are carried out,includes the mud logging device while drilling,hydraulic tongs,submersible blowdown equipment and pneumatic winch,in order to meet the construction requirements of L‑type coalbed methane horizontal well.The application of the improved TSJ-3000 water source drilling rig has effectively improved the working efficiency and economic benefit.
