A testing system and method for a support mechanism of a drilling traction robot

Abstract

The invention relates to a testing system and method for a supporting mechanism of a drilling traction robot. It is composed of supporting simulation system, telescopic simulation system, torsion simulation system, data acquisition system, control execution system and computer. The hydraulic piston is used to provide support force, traction force and torque. The hydraulic pressure is provided by the pressure pump, and the pressure is controlled by the electromagnetic overflow valve. The double-acting hydraulic pressure is controlled by the three-position four-way electromagnetic reversing valve. Pull and pressure sensor collection. The purpose of the present invention is to provide a drilling traction robot support mechanism testing system and method to measure key parameters such as the support force, traction force, and torque of the drilling traction robot, shorten the research and development cycle of the drilling traction robot, reduce the experimental cost of the drilling traction robot, and optimize the structure of the support mechanism The design provides experimental data reference, and promotes the theoretical research and engineering popularization and application of drilling traction robots.

Description

technical field [0001] The invention belongs to the field of drilling and completion, and in particular relates to a testing system and method for a support mechanism of a drilling traction robot. Background technique [0002] With the rapid development of my country's national economy and the improvement of people's living standards, my country's demand for energy has grown rapidly, the contradiction between energy supply and demand has become increasingly prominent, and the degree of dependence on foreign oil and natural gas has increased year by year. It climbed to 45.3%, which greatly exceeded the internationally recognized warning line and seriously threatened my country's energy security. With the deepening of exploration and development, tight oil and gas (such as shale gas, etc.) with low permeability and low porosity have gradually become the focus of exploration and development. For example, according to the 2018 United Nations Conference on Trade and Development r...

Problems solved by technology

In terms of the drilling traction robot experimental system, two patents have been invented: CN201710705983.2 and CN201710720406.0, but these two patents can only carry out the traction force, traction speed and control experiments of the drilling traction robot, and cannot test the support of the supporting mechanism force, traction, and torque parameters, the reliability evaluation experiment of the support mechanism of the drilling traction robot cannot be carried out, and the anti-blocking characteristic experiment cannot be carried out

[0007] Therefore, because the existing experimental systems related to the drilling traction robot are mainly complete machine experiment systems, the experiment preparation period is long, the cost remains high, and the experimental data reference cannot be provided for the optimal design of the support mechanism structure, which restricts the development of the drilling traction robot to a certain extent.
