The ground measurement and test operation is a necessary process before the production of the oil and gas well, and is a direct means for collecting and monitoring parameters such as the yield of the oil and gas well, the physical properties of a producing layer and the like. Separating oil, gas and liquid from the stratum product through a ground process, wherein the separated stratum gas needs to be ignited in a blowout pool through a gas blowout pipeline; when the pressure in the process exceeds a set value, the pressure needs to be relieved through an emergency blowout pipeline, and risks caused by overpressure of equipment are avoided. Therefore, the surface metering test process generally comprises two or more blowout pipelines.

In the ground measurement and test operation process of a desert oil field operation block (such as an operation block in a Tarim oil field tower), oil pipes with the size of 3-1/2' or more are generally adopted as a blowout pipeline, the oil pipes are required to be connected to a blowout pool all the time from a separator position, all the oil pipes are fixed on a movable foundation pier, and the total length can reach more than 100 m. The blowout pipeline and the movable foundation pier are made of steel materials and are heavy. Because the crane is limited by the soft sand foundation in desert terrain, the crane can not enter the operation, the movable base piers are uniformly distributed to the designated position only by means of shouldering of workers, and then oil pipes are shouldered one by one and connected to each base pier to form a blowout pipeline; when the operation is finished, the pipelines still need to be manually disassembled one by one and then recovered in a shouldering mode, so that the labor amount is huge, personnel injury is easy to cause, and the working time efficiency is very low.
