Abstract

The application relates to a downhole power drilling tool with a jam release device, which belongs to the technical field of power drilling tools, including: a power drilling tool, which includes a shell and a shaft, the shell is a hollow tubular structure, the shaft is located in the shell and It can be rotated in the housing; the card releasing device is located in the housing, and the card releasing device is used to connect the housing and the shaft in the triggered state, so that the shaft rotates synchronously with the housing. The jamming release device does not participate in the normal drilling operation of the downhole power drilling tool of the present application, and the jamming release device automatically connects the shaft rod and the housing to rotate as a whole after increasing the pump pressure of the drilling fluid when the jamming needs to be released. The jam-releasing device is located on the shaft in the casing and has a compact structure, which has little weakening of the structural strength of the shaft, small stress on the shaft, and long service life. A jam release device is set between the shell and the shaft, and the upper end of the shell is connected with the drill pipe, which can transmit the torque of the wellhead rotary table to the shell through the drill pipe, and then transmit the torque to the shaft and the drill bit through the jam release device, realizing the drill bit solution card.

Description

technical field [0001] The present application relates to the technical field of power drilling tools, in particular to a downhole power drilling tool with a jam release device. Background technique [0002] In the exploitation of oil and natural gas, the application of downhole power drilling tools is more and more extensive. The power drilling tools drive the drill bit to realize the formation drilling. Downhole power drilling tools, power drilling tools convert hydraulic energy into kinetic energy, driving the bottom hole drill bit to rotate. There are two common power drills: screw drills and turbo drills. For screw drilling tools, the drilling fluid enters the stator housing and drives the rotor screw that is eccentric to the stator housing to rotate. The rotor screw drives the cardan shaft and transmission shaft connected to it to rotate, thereby driving the drill bit at the lower end of the drilling tool to rotate. Turbodrilling tools use one or more stages of turbi...
