Description

Technical Field

[0001] This utility model relates to the field of oil and gas pipeline technology, specifically to a support grouting device for the internal passage of a casing in a long-distance oil and gas pipeline. Background Technology

[0002] Long-distance oil and gas pipelines typically span hundreds or even thousands of kilometers, transporting oil and gas resources from production sites to consumption sites. The transported oil products include refined petroleum products such as No. 0 diesel and No. 92 gasoline. When these pipelines pass through casing protection, grouting is required. This involves installing a support device inside the casing and grouting to ensure the stability and safety of the pipeline as it passes through the casing. Specifically, the support and grouting device includes a ring-shaped combined support body, multiple sets of rollers, and a grouting main pipe. The combined support body is fitted over the outside of the long-distance oil and gas pipeline. Multiple sets of rollers are circumferentially spaced on the lower outer side of the combined support body, and the grouting main pipe is axially fixed to the lower part of the combined support body. This design effectively reduces friction when the oil and gas pipeline passes through the casing, preventing wear on the pipeline's external anti-corrosion layer or the pipe body.

[0003] Because oil and gas pipelines have different models, their outer diameters vary. Therefore, when supporting and fixing them, it is impossible to adjust the support according to the outer diameter. This can lead to insecure pipe clamping, displacement, or vibration, which in turn affects the stability of the pipe when moving within the casing. Furthermore, if the pipe diameter is too small during grouting within the casing, the pipe will tilt downwards within the casing, resulting in excessive deviation in the amount of grout injected into the casing and affecting the quality of the grouting process. Utility Model Content

[0004] The purpose of this invention is to provide a support grouting device for the internal passage of casing in long-distance oil and gas pipelines, so as to solve the problems mentioned in the background art.
