A dual-discharge high-pressure manifold for fracturing

Abstract

The invention provides a double-discharging high pressure pipe manifold for fracturing. A first pressure relief pipe manifold and a second pressure relief pipe manifold are respectively connected at two ends of a four-way connection assembly, the other two ends of the four-way connection assembly are respectively connected with a first dual male reducer union and an integral dual male straight pipe assembly, one end of the integral dual male straight pipe assembly is connected with a Y-shaped tee joint, a second dual male reducer union and a second T-shaped tee joint in sequence, the other two ends of the second T-shaped tee joint are respectively connected with a Marti-Decker gauge and a discharging flange assembly, the other end of the first dual male reducer union is connected with a first T-shaped tee joint and the discharging flange assembly in sequence, and the other end of the first T-shaped tee joint is connected with an adapter, a transducer adapter and a pressure sensor in sequence. The double-discharging high pressure pipe manifold is capable of overcoming the defects and disadvantages of existing discharging pipe manifolds. Further, the structural functions of the discharging pipe manifold are increased, and the water power efficiency of a fracturing pump truck is improved.

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...
