Problems solved by technology

However, at present, most of the wax deposits are sampled manually, and researchers generally use blades and rulers for sampling and thickness measurement
Such sampling and thickness measurement methods can introduce large errors that can adversely affect wax deposition studies
Especially in the sampling process of deposits on the inner pipe wall far away from the pipe cut, this method produces larger errors and is extremely inconvenient to operate
At present, there is no device for accurate sampling of wax deposits at different spatial locations on the inner wall of the pipeline

Abstract

The invention relates to a sampling and thickness measuring device for wax deposits at different spatial positions in an oil conveying pipeline. The device comprises a fixed ring, a fixed bracket, a rotary bracket, a sampling device, and an illuminating device. The outer wall of the fixed ring is connected with one end of the fixed bracket; and the other end of the fixed bracket is connected withthe rotary bracket. One end of the sampling device is installed on the rotary bracket and the illuminating device is arranged at the other end of the sampling device. Therefore, sampling and thicknessmeasurement can be carried out on deposits at different spatial positions in a pipe; the sampling points are distributed widely and the operation precision is high; and movement in a radial directionand an axial direction can be checked precisely by the dividing ruler.

Description

Technical field [0001] The invention relates to a sampling thickness measurement device and method for wax deposits at different spatial positions in an oil pipeline, and can realize accurate and efficient sampling operations for wax deposits at specific positions in the pipeline. It can be used in various pipeline sediment sampling operations in the petrochemical industry. Background technique [0002] Wax deposition in crude oil pipelines is one of the serious problems that affect the flow safety during oil extraction and transportation. In recent years, oil development has gradually moved from land to sea, followed by the problem of low-temperature transportation in submarine pipelines, and the probability of wax deposition when waxy crude oil flows through the pipeline has greatly increased. The occurrence of wax deposition reduces the flow area of ​​the pipeline, increases the pressure of the pipeline, and reduces the transportation capacity of the pipeline. In severe cases...
