High-pressure manifold detection method

Abstract

Provided is a high-pressure manifold detection method. The method firstly draws up a trace number for a high-pressure manifold product, performs macroscopic inspection, functional inspection, wall thickness detection and sealing tests, conducts acoustic emission detection while performing the sealing tests, installs test signs on manifolds which are qualified for the sealing tests and the acousticemission detection, issues a test report, disassembles suspicious parts of the manifolds which leak in the sealing tests or are unqualified for the acoustic emission detection, polishes the inner andouter surfaces, conducts magnetic powder detection, judges the unqualified parts as the unqualified parts, conducts product assembly, the sealing tests and test sign installation on the qualified parts in turn, and finally issues the test report. The detection efficiency of the method is high, and the risk of fracturing operation is greatly reduced.

Description

technical field [0001] The invention relates to the field of detection of high-pressure manifolds, in particular to a detection method for high-pressure manifolds. Background technique [0002] Fracturing is one of the important means for the petroleum industry to increase the production of oil and gas wells. For low-permeability oil and gas fields, fracturing is already an indispensable technical measure. In addition to the gradual development of shale gas unconventional energy in recent years, fracturing It shows an upward trend of large displacement, high pressure and long continuous operation time. As an important part of the fracturing operation, the high-pressure manifold is prone to quality accidents such as fracture and puncture leakage during the operation process, resulting in low fracturing efficiency and high safety risks. Therefore, the high-pressure manifold is tested Particularly important. The traditional inspection process is mainly carried out through the...

Problems solved by technology

As an important part of the fracturing operation, the high-pressure manifold is prone to quality accidents such as fracture and puncture leakage during the operation process, resulting in low fracturing efficiency and high safety risks. Therefore, the high-pressure manifold is tested especially important

The traditional inspection process is mainly carried out through the steps of visual inspection, disassembly, magnetic particle inspection, and pressure test. This inspection and maintenance process has low efficiency, and many rely on the experience of maintenance personnel. Surface crack defects, more important internal and deep active defects cannot be found, and quantitative detection of other key parameters of high-pressure manifolds cannot be formed
