Description

一种深井钻机整体式钻进压力控制系统 One kind of deep drilling rig integral pressure control system

技术领域 FIELD

[0001] 本发明涉及一种深井钻机压力控制系统,具体是一种深井钻机整体式钻进压力控制系统。 [0001] The present invention relates to a deep drilling rig pressure control system, particularly a deep drilling rig integral pressure control system.

背景技术 Background technique

[0002] 深井钻机,是一种适合水文地质勘测、工农业水井、地下坑道、通风孔、浅层煤层气及地热采暖孔的工程中成孔作业的施工机械。 [0002] deep drilling rig, is a suitable hydro-geological surveying, construction machinery and agricultural wells, underground tunnels, ventilation holes, coal bed methane and shallow geothermal heating project bore holes into the job. 它主要利用液压转盘驱动钻杆钻进,各钻杆之间通过螺纹连接;当钻孔深度较浅时,由于钻杆数量少,重量轻,因此需要施加额外的加压力使之满足钻进压力的要求,并且该加压力要随钻深的增加(即钻杆自重的增加)而逐渐减小,因此需要实时调节钻进压力。 It is mainly driven by a hydraulic rotary drilling rod, by a threaded connection between the drill pipe; when drilling shallow depth, since the number of drill rods, light weight, thus requiring additional pressing force is applied so as to satisfy the pressure drilling requirements, and the pressure applied to the drilling depth increases (i.e., an increase in weight of the drill pipe) is gradually reduced, requiring real-time adjustment hole pressure. 当钻孔较深时,钻杆数量增多,重量变大,因此作用在钻头上的压力变大,当钻杆重量大于所需钻进压力时,需要施加额外的提升力(即减压力)来减小作用在钻头上的压力。 When drilling deeper, the number of the drill pipe increases, the weight increases, so the pressure acting on the drill bit is increased, the drill pipe when drilling a pressure greater than the desired weight, the additional lifting force needs to be applied (i.e. decrease pressure) reducing the pressure acting on the drill bit.

[0003]目前,国内的深井钻机研发企业均采用加压,减压分开控制的方式。 [0003] At present, the domestic research and development of deep drilling rig companies are using compression, decompression mode controlled separately. 加压工况普遍采用机械重力式钻铤加压,即依靠钻杆上端金属钻铤的重量来实现加压钻进,这种形式不仅笨重落后,而且加压力不可调节。 Mechanical pressing conditions commonly used gravity pressurized drill collar, the upper end of the metal rod which rely on the weight of the drill collars to achieve pressurized drilling, behind this form only cumbersome, but the pressing force can not be adjusted. 国外的深井钻机研发企业普遍采用液压控制的形式进行加压和减压钻进,但均为分体式的,但分体式设计使操纵面板的体积增大,给面板的排布设计带来一定的困难。 Deep drilling rigs foreign R & D enterprises generally take the form of hydraulic control of pressurizing and depressurizing drilling, but are split, but split design increases the volume control panel, arranged to bring some of the design panel difficult.
