Description
技术领域 technical field
本实用新型涉及一种采矿钻井设备，属于采矿设备领域。 The utility model relates to a mining drilling equipment, which belongs to the field of mining equipment.
背景技术 Background technique
现有技术中的常规液力加压器，由钻柱、接头、活塞、缸筒、活塞杆、花键联接和钻头组成。其工作原理主要靠钻井液通过钻头喷嘴时所形成的压力降，在活塞上表面产生推力。该推力即是传递到钻头上的钻压。工作行程就是活塞在缸筒内轴向运移的长度。这种结构的加压器只有在活塞没有接触接头时，才起到恒定加压的作用，当活塞接触接头时，继续下放钻柱，就会在钻头上形成过大的压力，导致钻头过早损坏。另外，由于这种加压器地面没有显示装置，司钻很难掌握井下情况、井下加压器是否加上压地面无法知道。因而，无论从操作上还是使用上，常规液力加压器都存在着严重缺陷。 The conventional hydraulic pressurizer in the prior art is made up of drill string, joint, piston, cylinder barrel, piston rod, spline connection and drill bit. Its working principle mainly relies on the pressure drop formed when the drilling fluid passes through the nozzle of the drill bit to generate thrust on the upper surface of the piston. This thrust is the weight-on-bit transmitted to the drill bit. The working stroke is the length of the axial movement of the piston in the cylinder. The pressurizer with this structure only plays a role of constant pressure when the piston does not touch the joint. When the piston touches the joint, if the drill string continues to be lowered, excessive pressure will be formed on the drill bit, causing the drill bit to prematurely damage. In addition, because there is no display device on the surface of this pressurizer, it is difficult for the driller to grasp the downhole situation, and it is impossible to know whether the downhole pressurizer is added to press the ground. Thereby, no matter from operation or use, all there is serious defect in conventional hydraulic pressurizer.
