Combined tool for manufacturing manifolds

Abstract

A combined tooling made of manifolds, including two parts: prefabricated tooling and assembly tooling used in conjunction with the prefabricated tooling, wherein the prefabricated tooling is provided with: an external support frame and several internal support members fixed on the external support frame , respectively fixed on the internal support, and the limit joints that restrain the branches of the manifold; the assembly tool is equipped with: a basic frame, two branch support beams that are opposite and vertically installed on the basic frame, and are evenly fixed on the Several mother pipe support beams on both sides of the foundation frame, a mother pipe limit frame fixed on one side of the foundation frame, several mother pipe limit devices fixed on the mother pipe support beams, and a Anti-deformation hydraulic controller. The invention not only solves the problem of welding deformation in the process of manifold welding, but minimizes the adverse effects caused by welding deformation in the process of manifold welding; moreover, it also improves the construction accuracy of manifold fabrication and speeds up the fabrication of manifolds construction efficiency.

Description

technical field [0001] The invention relates to manifold prefabrication, in particular to a combination tool for manifold fabrication. It belongs to the field of offshore oil engineering. Background technique [0002] At present, in the offshore oil wellhead platform, the well fluid and gas produced from underground oil and gas reservoirs are transported to the manifold through the Christmas tree. Manifolds are divided into two types: production manifolds and test manifolds. Among them, the function of test manifolds is to transport the produced well fluid and gas of each well to the metering separator for separation and measurement; and the production manifold It is: to collect the liquid and gas of each oil well and transport them to the oil and gas separation system. When process treatment needs to inject water into the ground, the sewage from the water injection system is pressurized by the water injection pump, and then distributed to the water injection wells through...
