Embodiment Construction

[0059] 1. Turn on the metal magnetic memory detector and calibrate it, select a suitable probe according to the shape characteristics of each detection part of the hydraulic energy storage workover rig, and start scanning. When there is a large leakage magnetic field gradient, mark it with a marker pen.

[0060] 2. Through a comprehensive scan of the hydraulic energy storage workover rig's main stress-bearing components, damaged or corroded components, sudden changes in the cross-section of the derrick, key component connections, key welds and other parts of the hydraulic energy storage workover rig, it was found that There are 3 stress concentration areas, all of which are located on the 3 fixed ear plates at the lower end of the main oil cylinder. According to the metal magnetic memory test results and the force characteristics of the derrick, a total of 32 measuring points were arranged in this test. The middle section of the column (3# module), the rotating platform (4# m...

Abstract

The invention provides a method for testing the bearing capability of a hydraulic energy storage workover rig, and the method employs the technology of metal magnetic memory to detect a stress concentration region of a derrick, and then pastes a strain gage in the region for stress detection. Therefore, the method can calculate a more accurate actual bearing capability of the derrick, so as to guide the safety supervision of petroleum drilling production. The method solves a problem that a conventional detection method and standard cannot be used for the testing of the bearing capability of a hydraulic energy storage workover rig, and can accurately test the bearing capability of the hydraulic energy storage workover rig.

Description

technical field [0001] The invention belongs to the technical field of safety detection of petrochemical equipment, and relates to a test method for the bearing capacity of a hydraulic energy storage workover machine, in particular to a telescoping hydraulic cylinder of an in-service hydraulic energy storage workover machine with different damage or deformation On-line safety detection of the carrying capacity of a special-shaped derrick, that is, a test method for the carrying capacity of a hydraulic energy storage workover rig. Background technique [0002] In the oil and gas industry, the derrick is the key equipment in the oil drilling process, and the safety of the oil derrick is directly related to the safety of employees and national property. As an important measure to ensure oil drilling safety, derrick detection technology has been fully implemented in various oil fields. [0003] As a new type of workover equipment, hydraulic energy storage workover rig is mainly...
