Double-discharge high-pressure manifold for fracturing

Abstract

The invention discloses a double-discharge high-pressure manifold for fracturing, and particularly relates to the technical field of petroleum equipment.The double-discharge high-pressure manifold is characterized in that a circulation cavity seat is connected with a connector pipe in a sleeving mode, a sliding block slides in a sliding groove, positioning and guiding of the connector pipe and the circulation cavity seat are facilitated, a plurality of positioning blocks enter a plurality of positioning grooves, and accurate installation of the connector pipe and the circulation cavity seat is achieved; the two fixing rods are pressed to drive the concave sleeve base to move synchronously, the concave sleeve base and the circulation cavity base rotate in a threaded mode, the inner wall of the concave sleeve base makes contact with the lantern ring plate, the lantern ring plate slides on the outer portion of the connector pipe, the connector pipe extrudes the multiple springs, and the concave sleeve base is connected with the outer wall of the circulation cavity base in a threaded and sleeved mode. The connector pipe and the circulation cavity base are connected more tightly, and normal circulation work of the manifold is guaranteed; the direction of the Y-shaped tee joint can be adjusted by shifting the butt-joint mounting pipe, so that the butt-joint mounting pipe rotates in the containing cavity, and the convex ring and the concave ring groove move to adapt to mounting of the Y-shaped tee joint and the fracturing truck.

Description

technical field [0001] The invention relates to the technical field of petroleum equipment, in particular to a dual-discharge high-pressure manifold for fracturing. Background technique [0002] In unconventional oil and gas exploration operations, due to special geological conditions, most oil and gas reservoirs have extremely low porosity and permeability, and it is necessary to fracturing the reservoir to obtain industrial oil and gas flow; The equipment necessary for the fracturing process. Currently, the fracturing plunger pump installed on the fracturing truck is a five-cylinder pump. The two discharge ports of the fracturing plunger pump are connected to the high-pressure discharge manifold at one end and the safety manifold at the other end. When the fracturing plunger pump is working, one of the two discharge ports provides a discharge channel for the fracturing fluid, and the other does not work under normal circumstances, and only serves as a safety channel.

Problems solved by technology

[0003] The invention patent with the publication number CN103334732B discloses a dual-discharge high-pressure manifold for fracturing. The design of the double-discharge high-pressure manifold is adopted. Under a certain pressure, the flow rate of the fluid inside the manifold is reduced, and the impact of the fluid on the pump is reduced. The erosion of the discharge end of the head body, while the displacement is larger, the water power efficiency is higher; the suction performance of the five suction ends is improved by adopting the two-way discharge structure; but the connection of the pipes in this manifold structure is not tight enough, and Y The type tee does not have a rotating structure, so it cannot be adapted to the installation with the fracturing vehicle, and the installation effect is poor
