Abstract

The invention provides a drilling speed-increasing tool. The drilling speed-increasing tool includes a casing, a driving assembly and an impact assembly. The casing has a flow passage, and the impact assembly includes: a first joint connected to the casing, and the first joint has an impact chamber; The swinging member has a first swinging position and a second swinging position relative to the first joint, the swinging member is located in the impact chamber and divides the impacting chamber into a first cavity and a second cavity; the flow guide has a communication channel The guide channel, the guide channel is selectively communicated with the first cavity or the second cavity, the driving assembly is drivingly connected with the guide member, so as to drive the guide member to rotate in the same direction relative to the housing, and the guide member is rotating During the process, the communication state of the guide channel and the first cavity and the second cavity is switched, so as to drive the swing member to swing between the first swing position and the second swing position and collide with the first joint. Through the technical solution provided by the application, the problem of low drilling speed in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of oil field exploration and development, in particular to a drilling speed increasing tool. Background technique [0002] Currently, screw drilling tools are usually used for drilling, and the screw drilling tools can effectively control the trajectory of the wellbore. Specifically, the screw drilling tool transmits the torque and rotational speed required for the drill bit to break the rock to the drill bit, and then drives the drill bit to break the rock. [0003] However, in the prior art, because the screw drilling tool only relies on the rotation of the drill bit to break rock, the screw drilling tool has the problem of low drilling speed. Contents of the invention [0004] The invention provides a drilling speed increasing tool to solve the problem of low drilling speed in the prior art. [0005] The invention provides a drilling speed-increasing tool. The drilling speed-increasing tool includes a...
