Test board of deepwater oil tube hanger

Abstract

The invention discloses a test board of a deepwater oil tube hanger. The test board comprises a bottom plate, and a supporting bracket installed on the bottom plate, wherein the top end of the supporting bracket is equipped with a bearing substrate used for mounting the deepwater oil tube hanger, and the upper part of the bearing substrate is relatively provided with a seating slip. The test board can stably place the long and thin deepwater oil tube hanger on the supporting bracket; moreover, through the abutting between the seating slip and the bearing substrate, the connection and conversion between an external hydraulic pipeline and an internal hydraulic circuit of the deepwater oil tube hanger can be realized; the test board solves the stability of the deepwater oil tube hanger in the course of testing and difficult abutting operation; meanwhile, the overall sealing property of the deepwater oil tube hanger is greatly improved.

Description

technical field [0001] The invention relates to a test device, in particular to a test stand for a deep-water tubing hanger. It belongs to the field of offshore oil engineering. Background technique [0002] The deepwater tubing hanger is one of the key equipments for deep sea oil and gas exploitation. By hanging the tubing inside the Christmas tree, it not only provides oil flow production channels, but also provides access for downhole hydraulic control pipelines, cables and chemical agent injection pipelines; it is the connection Hub components for downhole oil pipes and subsea oil pipelines. In the process of oil and gas exploitation, once the deepwater tubing hanger fails, it may cause oil and gas leakage to pollute the marine environment, and may even cause a blowout accident. [0003] At present, because there is no special test device for deep-water tubing hangers, this will seriously restrict the development of deep-water tubing hangers. [0004] In order to solv...

AI Technical Summary

Problems solved by technology

[0006] The main purpose of the present invention is to overcome the above-mentioned shortcomings existing in the prior art, and to provide a deep-water tubing hanger test stand, which can not only stably seat the deep-water tubing hanger with a slender structure on the support frame, but also make the deep-water tubing hanger The hanger remained stable throughout the testing process; moreover, the connection and conversion of the external hydraulic pipeline and the internal hydraulic circuit of the deepwater tubing hanger were realized through the docking between the seating slips and the receiving base; The stability of the hanger during the test and the difficulty of docking operation; at the same time, the overall sealing performance of the deepwater tubing hanger is greatly improved through the metal seal
