Manifold device

Abstract

The invention discloses a manifold device. The manifold device is arranged on the ground, and used for transporting a high-pressure medium to a stratum. The manifold device comprises a main pipe and auxiliary pipes, wherein each auxiliary pipe comprises a hard pipeline, a check valve and a hard pipe elbow which are sequentially connected. According to the invention, each of the main pipe, the hard pipeline and the hard pipe elbow of the manifold device is designed into a multilayer structure formed by arranging an inner core pipe layer, a low-temperature-resistant protection layer and a pipe body layer in a bonding manner from the inside to the outside; each inner core pipe layer is made from a low-temperature-resistant alloy steel material; and each low-temperature-resistant protection layer is made from a foam glass material. Each pipe body with the multilayer structure has a low-temperature-resistant function, and a risk of breakage due to cold damages of a low-temperature medium to the pipe body can be greatly reduced, and equipment losses, personal injuries and environment pollution due to the breakage of the pipe body are avoided; and moreover, each pipe body with the multilayer structure and the low-temperature-resistant protection function is capable of isolating a heat conduction action thereof with the outside, and reducing the cold losses of the low-temperature high-pressure medium, so as to achieve a temperature of construction requirements; and construction efficiency is increased.

Description

technical field [0001] The invention relates to the field of oil and gas exploitation, in particular to a manifold device. Background technique [0002] A manifold is a combination of multiple pipes. With the development of the petrochemical industry, high-pressure manifolds used to transport high-pressure media to formations are widely used in oil fields and coalbed methane well operations. The high-pressure manifold, also known as the collection of high-pressure fluid control parts, is mainly used on pipelines for oil field cementing, fracturing, acidizing tests and other construction operations. It connects the high-pressure output end of the construction vehicle to the wellhead through the high-pressure pipeline to achieve transportation Purpose of high pressure fluid medium. [0003] At present, the high-pressure manifold devices used in coalbed methane wells and oil field sites are composed of a combination of multiple pipe bodies, and each pipe body is a single-laye...
