Abstract

The 175MPa high-pressure large-drift-diameter fracturing manifold comprises a prying frame assembly and a collecting pipe combination, the collecting pipe combination is arranged at the top end of the prying frame assembly, a plurality of double-clip type acid-resistant butterfly valves are arranged on the outer walls of the two sides of the collecting pipe combination at intervals, branch pipe assemblies are arranged on the two sides of the collecting pipe combination respectively, and the branch pipe assemblies are connected with the prying frame assembly. The two branch pipe assemblies are communicated through a first flange short-circuit connector. The invention aims to provide the 175MPa high-pressure large-drift-diameter fracturing manifold which is high in pressure bearing capacity and safe to use.

Description

technical field [0001] The invention relates to the technical field of oil field fracturing equipment, in particular to a 175MPa high-pressure large-diameter fracturing manifold. Background technique [0002] Hydraulic fracturing is the use of surface high-pressure pumps to squeeze fracturing fluid with higher viscosity into the oil layer through the wellbore. When the injection rate of fracturing fluid exceeds the absorption capacity of the oil layer, a very high pressure is formed on the bottom hole oil layer. When this pressure exceeds the fracturing pressure of the oil layer rock near the bottom hole, the oil layer will be forced apart and fractures will occur. At this time, the fracturing fluid will continue to be squeezed into the oil layer, and the fracture will continue to expand to the inside of the oil layer. Fracturing manifolds are used to build up hydraulic pressure during hydraulic fracturing. Existing fracturing manifolds have complex structures and are time...
