Problems solved by technology

However, in general, the working conditions of fracturing operations are complex and there are many noise sources in the field environment, so the actual measured signal is inherently nonlinear and contains a lot of noise. It is difficult to find the corresponding characteristics if the spectrum is directly analyzed Frequency, which makes it difficult to extract fault features, and ultimately affects the accuracy of equipment health status evaluation results

Abstract

The present application provides a method and device for evaluating the health state of fracturing equipment during operation, wherein the method includes: obtaining target vibration data of fracturing equipment during operation; using an ensemble empirical mode decomposition algorithm to decompose the target vibration data, Obtain multiple eigenmode functions; determine the eigenmode energy corresponding to each eigenmode function in multiple eigenmode functions, and obtain multiple eigenmode energies; according to the trained classifier model and multiple eigenmode energies , to determine the health status of the fracturing equipment. The above method can accurately determine the health state of fracturing equipment, provide technical support for safe and orderly fracturing construction, and help operators understand changes in the health state of fracturing equipment and capture abnormal states in time.

Description

technical field [0001] The present application relates to the technical field of gas reservoir exploitation, in particular to a method and device for evaluating the health status of fracturing equipment during operation. Background technique [0002] Shale gas reserves are abundant. Because shale gas is mostly distributed in remote mountainous areas and is deep from the surface, it is difficult to exploit it. It is often necessary to use horizontal wells + multi-stage fracturing technology to increase production. With the continuous increase of pressure and displacement in fracturing construction operations, the development of fracturing equipment is also developing in the direction of high pressure and large displacement. [0003] Currently, 2500 and 3000 types of fracturing equipment are widely used in the shale gas development process. The number of fracturing equipment configured for a single well in shale gas fracturing construction is about 18. Generally, each well req...
