Problems solved by technology

[0004] In view of the above problems, existing researchers have proposed the following solutions: ① By changing the tooth shape of the driving wheel teeth to improve the friction coefficient of the furrow, thereby increasing the traction force, but the conical and triangular prism tines used are prone to problems. Problems such as wear and insufficient strength; ②The traction force of the tractor can be improved by designing the locking mechanism of the dovetail slider, but the working efficiency of the tractor cannot be guaranteed when the retractor moves forward

Abstract

The invention belongs to the technical field of well logging equipment, and relates to a coupling bionic driving wheel capable of improving the traction force of a wheel type tractor, and the tooth surface of a wheel tooth is provided with a convex structure simulating the surface topography lines of a scapharca subcrenata shell; when the driving wheel walks along the pipe wall under the action of certain positive pressure, the furrowing effect can be generated when the wheel teeth are wedged into the surface of the pipeline, a certain groove is formed in the surface of the pipeline, the friction force between the tooth surfaces of the wheel teeth and the pipe wall can be increased through the design of the columnar coupling element body structure, and then the traction force of the wheel type tractor is improved; the follow-up use of the sleeve is not affected, and compared with a conventional driving wheel, the driving wheel has better traction characteristics; meanwhile, due to the design of the convex spherical coupling element body structure, the obstacle crossing capacity and the deadhesion and adsorption reduction capacity of the tractor driving wheel can be enhanced, the abrasion resistance and the heat dissipation capacity of the wheel teeth are improved, and therefore the service life of the driving wheel is prolonged.

Description

technical field [0001] The invention belongs to the technical field of well logging equipment, relates to a wheeled tractor, in particular to a coupled bionic drive wheel which can improve the traction force of the wheeled tractor. Background technique [0002] With the rapid development of society and economy, the demand for oil in all walks of life is increasing day by day, and the transition of oil exploitation from middle and shallow layers to deep layers has become an inevitable trend. In the process of deep oil exploitation, there will always be failures of different degrees, and certain workover operations and testing work are required to ensure the normal production of oil and gas, which puts forward higher requirements on the delivery capacity of logging tools. . [0003] However, the existing wheel-type tractors for horizontal wells need to overcome the increased frictional resistance between the cable and the well wall as the mining depth increases, and the tract...
