Problems solved by technology

[0003] Due to the complexity of the internal environment of oil and gas pipelines, the kinematics and dynamics of pigs under circumferentially limited conditions become extremely complex.
The motion law and dynamic characteristics of the pig are affected by factors such as friction, pipe annular welds, corrosion pits, pipe deformation, and pipe wall thickness. It is necessary to analyze and study the dynamic characteristics of the pig during operation. At present, there is no device for monitoring the dynamic characteristics of the pig during its movement.

Embodiment Construction

[0029] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0030] Such as figure 1 and figure 2 As shown, the present invention provides a test device 100 for monitoring the operation of the pig in the pipeline, and the test device can be used to study the dynamic characteristics of the pig in the process of running in the pipeline. The test device 100 includes a support 1, on which a horizontal test pipeline 2 is fixedly supported, and the first end and the second end of the horizontal test pipeline 2 are respectively arranged correspondingly to the first end and the second end of the support 1. figure 2 , the first end of the horizontal test pipe 2 and the first end of the support 1 face to the left, and the second end faces to the right. The first end of the horizontal test pipe 2...

Abstract

The invention relates to a test device for monitoring the operation of a pipe pig in a pipeline. A horizontal test pipeline is fixedly supported on a bracket. barrel. The pig is located in the ball-emitting cylinder at the initial position, and is located in the ball-receiving cylinder at the final position. A servo winch is fixed at the first end of the bracket, one end of the rope is wound on the roller of the servo winch, and the other end is bypassed by a fixed pulley fixed at the second end of the bracket, and connected to the pig through a tension sensor. Under the pull of the servo winch and the rope, the pipe pig passes through the ball-emitting cylinder and the horizontal test pipe to move into the ball-receiving cylinder; the pig is also equipped with an acceleration sensor. The invention can be used to study the dynamic characteristics of the pig in the process of running in the pipeline.

Description

technical field [0001] The invention relates to a monitoring test device for the movement behavior of a pipeline pig with stepless speed regulation, in particular to a test device for monitoring the operation of the pig in the pipeline. Background technique [0002] With the prolongation of the service life of the pipeline, scaling and impurity adhesion will occur in different degrees on the inner wall of the pipeline, resulting in a decrease in pipeline transportation efficiency or even blockage. Regular pigging and inspection operations are one of the essential processes for the operation and maintenance of oil and gas pipelines. Pigging operation is an important means for the commissioning and safe operation of oil and gas pipelines. Pigs generally refer to the working tools in the pipeline driven by the pressure difference of the pipeline transportation medium, and are also the main tools for pigging operations. [0003] Due to the complexity of the internal environment...
