The fracturing manifold mainly comprises a main body, a control valve and a union, and is in a tree-fork shape; the tree-fork-shaped main body is formed by welding high-quality alloy steel pipes and forming a forged tee joint, the pressure-bearing capacity of welding processing is 60Mpa, and the pressure-bearing capacity of forging processing is 70 Mpa; the control valve is usually a ball valve or a plug valve, and the pressure bearing capacity is 70 Mpa; union is also called movable joint or union. The pipe fitting for connecting the two pipes can separate the two pipes without moving the pipes, thereby being convenient for installation and maintenance.
In the production process of the petroleum and natural gas, the petroleum and natural gas are transported by adopting a fracturing manifold, so that stratum gravel and fracturing gravel can reach the ground along with oil gas, and sand production of an oil gas well can cause serious abrasion of the ground and underground equipment, even cause well blockage; maintenance workload such as sand washing pump inspection and ground tank cleaning is increased sharply; the production is stopped due to sand blocking of a sand-buried oil layer or a shaft; even cause the wall of a well to collapse and damage the oil casing pipe when the sand production is serious, increase the problems of oil and gas exploitation cost and the like.
