Fracturing conveying ground manifold system

Abstract

The invention discloses a fracturing conveying ground manifold system. The fracturing conveying ground manifold system comprises a fracturing tree, a high-low pressure manifold device, a high-pressureflange conveying pipeline, a ground fracturing control manifold device, an offset flange mechanism and a corner pipeline, wherein the high-low pressure manifold device is linearly connected with theground fracturing control manifold device through the high-pressure flange conveying pipeline; the ground fracturing control manifold device is connected with the fracturing tree through the offset flange mechanism and the corner pipeline; and the offset flange mechanism and the corner pipeline can realize adjustment of different heights and directions between the ground fracturing control manifold device and the fracturing tree. The fracturing conveying ground manifold system has the advantages that the whole manifold system is large in displacement, simple in structure, simple in layout, fewin pipelines, few in joints, linear in conveying, relatively low in kinetic energy loss and capable of being separated from the ground, effectively prolonging the service life of the manifold, realizing multi-wellhead zipper type operation and improving the operation efficiency of a fracturing well factory.

Description

technical field [0001] The invention relates to the technical field of fracturing transportation, in particular to a ground manifold system for fracturing transportation. Background technique [0002] The fluid delivery channel between the fracturing vehicle and the fracturing wellhead in the conventional fracturing site is connected by a union-shaped high-pressure pipeline, that is, the assembly of the high-pressure pipeline is realized through the rotatable and sealed connection of the union. The existing union There are 2〞, 3〞 and 4〞 specifications for the pipe diameter, and the largest existing specification is 4〞. Therefore, due to the above-mentioned structure and process limitations, the current high-pressure pipeline has a smaller aperture, which is allowed by a single high-pressure pipeline. The maximum displacement is low, and it is difficult to meet the transportation requirements of the current large displacement of fracturing. [0003] In order to meet the cons...

AI Technical Summary

Problems solved by technology

A large number of high-pressure union pipelines need a large number of joints to realize the series-parallel connection in order to achieve large-displacement transportation, and the direction can be changed through swivel elbows. It will be a multi-pipeline, multi-joint, and multi-bend conveying system, and such a conveying system has many leakage points, complex layout, inconvenient installation, severe elbow vibration and short service life, etc.
