Description

technical field [0001] The invention belongs to the field of petroleum equipment, in particular to a discharge manifold system for fracturing. Background technique [0002] In the development process of conventional oil and gas fields, it is often necessary to fracture the reservoir to obtain better oil and gas passages after the oil and gas wells enter the late stage of production to increase the production of single wells. In unconventional oil and gas exploration operations, due to special geological conditions, the Most gas reservoirs have extremely low porosity and permeability, and the reservoirs must be fractured to obtain industrial oil and gas flow. Fracturing equipment is the necessary equipment for fracturing the reservoir. The fracturing equipment is composed of fracturing truck, sand mixing truck, manifold truck, instrument truck and auxiliary equipment. During construction, the fracturing fluid passes through the fracturing The fracturing plunger pump on the f...

AI Technical Summary

Problems solved by technology

The problems existing in the existing discharge manifold mainly include: (1) Since the plunger pump has five water inlets, under the condition of large displacement, the flow rate of the single-discharge high-pressure manifold structure is very high, and it is easy to cause the discharge end of the pump head body to be damaged. Early damage; (2) As the distance between the suction end and the discharge port increases, the suction performance of the five suction ends of the plunger pump gradually decreases; (3) The single-discharge high-pressure manifold pipeline can only be fixed by the support of the ground. Under heavy working conditions, the pipeline is prone to violent vibration, which will cause damage to the connecting bolts of the discharge flange and premature failure of the discharge flange

When the single-discharge high-pressure manifold structure works under high-pressure and large-displacement conditions, the structure and function are single, and the displacement is greatly limited, which reduces the water power efficiency of the pump truck and is difficult to meet the fracturing requirements under large-displacement conditions.
