Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as figure 1 Shown, a kind of turbine launcher of the present invention, a kind of turbine launcher, comprises power assembly 2, filter assembly 1 and rotary percussion micro-seismic launch assembly 3, filter assembly 1, power assembly 2 and The rotary-impact micro-seismic launch assembly 3 is connected by self-locking thread, which is convenient for installation and disassembly, and the connection is firm, which prevents the tripping phenomenon caused by complicated working conditions; the power assembly 2 is a component of the source power of the launcher. The function of driving the blades of the stator-rotor assembly 24 (turbine section) to rotate relatively, thereby driving the power main shaft 21 to rotate, thereby generating the source power of rotation.

[0020] Such as image 3 As shown, the power assembly 2 includes a mai...

Abstract

The present invention relates to drilling equipment, in particular to a turbine type launcher. The launcher includes a filter assembly, a power assembly and a rotary impulse microseismic launch assembly connected together by self-locking threads. Each assembly is connected by self-locking threads, which is easy to disassemble and install and has good connection reliability, preventing tripping caused by complicated working conditions; the filter assembly can effectively filter the solid particles in the drilling fluid and prevent the solid particles in the drilling fluid from affecting the power The stator-rotor group in the assembly and the emission shock source in the rotary impact micro-seismic assembly cause damage; the cooperation of the double female sub-section and the main shaft sub-section can increase the number of stator-rotor components on the powertrain and increase the power output torque ; The reaction force of the spring is applied to the launch impact body, which further makes the launch impact body produce axial impact; the impact frequency can be changed by adjusting the speed of the launch connecting rod; the launcher generates microseismic during the drilling process and cooperates with ground equipment Use to evaluate reservoirs.

Description

technical field [0001] The invention relates to a drilling equipment, in particular to a turbine launcher. Background technique [0002] With the development of oil and shale oil and gas drilling technology and the increasing difficulty of drilling, the innovation of drilling tools is urgently needed, and the on-site production and application of high-efficiency drilling tools that are safe, increase the mechanical penetration rate, and shorten the drilling cycle are needed. The downhole power drilling tool has no axial impact function, the mechanical penetration rate is not high, the working life is not long, and the tripping time is long. Contents of the invention [0003] In order to solve the above problems, the present invention provides an axially adjustable frequency turbine transmitter, which is installed on the transmission shaft of the turbodrill to provide axial impact force, increase the drilling speed of the drilling machine, and shorten the drilling time. cy...
