Abstract

The invention relates to the technical field of particle impact rock breaking high-pressure granule injection devices, in particular to a positive pressure type rigid granule high-pressure injection device. The injection device comprises a tank body, a driving pulley, a driven pulley, a transfer track, a rigid granule connecting ladle, a conveying pipe and a transmission device, wherein the upper part of the tank body is provided with a rigid granule inlet, the driving pulley and the driven pulley are arranged in the lower part of the tank body, the elevation of the top of the driving pulley is higher than that of the top of the driven pulley, the inclined transfer track with high left and low right is arranged between the driving pulley and the driven pulley, the rigid granule connecting ladle is arranged below the driving pulley, the conveying pipe is fixedly arranged on the rigid granule connecting ladle, the lower end of the conveying pipe passes through the bottom of the tank body and is positioned below the tank body, and the transmission device drives the driving pulley to rotate. The injection device has reasonable and compact structure, is convenient to use, can convey rigid granules to the pit bottom through the transfer track, and has the characteristics of high efficiency, fastness and high conveying quality.

Description

technical field [0001] The invention relates to the technical field of a high-pressure particle injection device for particle impact rock breaking, and is a positive-pressure rigid particle high-pressure injection device. Background technique [0002] With the continuous depletion of shallow oil and gas resources in my country, it is bound to develop into deep wells and hard formations, and there are abundant deep oil and gas resources in my country, and this development is imperative. At present, from the perspective of the existing rock-breaking mechanism of drilling technology, there are mainly three basic forms of mechanical rock-breaking, hydraulic rock-breaking and impact rock-breaking. Mechanical rock breaking is the most widely used drilling method in drilling technology. Hydraulic rock breaking mainly includes abrasive jetting and hydraulic jetting. Abrasive jetting can assist the drilling process and improve drilling speed in drilling, but at the same time, the c...
