Embodiment Construction

[0011] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0012] Such as figure 1 As shown, the strap-type drilling riser fixing bracket structure of the present invention includes hydraulic pipeline U-shaped clamp 1, choke / kill pipeline U-shaped clamp 3, mud pressurized pipeline U-shaped clamp 8, hydraulic pipeline U-shaped clamp 1. The U-shaped card of the choke / kill pipeline 3 and the U-shaped card 8 of the mud booster pipeline are all provided with perforations. The perforations of the three U-shaped cards are connected in series with a strap 7 of high-strength material, and the interface of the strap 7 is set Bolts 5 and nuts 6 are used to adjust the tightness of the strap 7, and the contact between the strap 7 and the riser is provided with a main pipe pad 1 2 and a main pipe pad 2 4 .

[0013] Among them, the U-shaped card 1 of the hydraulic pipeline, the U-shaped card 8 of the mud pressuriz...

Abstract

The invention discloses a strap-type drilling riser fixing bracket, which comprises a hydraulic pipeline U-shaped clamp, a throttle / kill pipeline U-shaped clamp, a mud pressurized pipeline U-shaped clamp, a hydraulic pipeline U-shaped clamp, a throttle / pressure clamp Both the U-shaped card of the well pipeline and the U-shaped card of the mud booster pipeline are provided with perforations. There are straps connected in series in the perforations of the three U-shaped cards. bolt. The beneficial effect of the device of the present invention is that the structure is simple and compact, light in weight, easy to install, and the overall rigidity is good; it can be freely and flexibly adjusted according to the distribution position of the auxiliary pipeline, thereby improving the adaptability of the fixed bracket and effectively reducing the cost of production and procurement ; Each U-shaped card is made of plastic and alloy material skeleton, which greatly reduces the overall weight, and enhances the flexibility of the connection and contact between the auxiliary pipeline and the U-shaped card.

Description

technical field [0001] The invention belongs to the technical field of offshore oil drilling equipment, and is a device for fixing and supporting a single auxiliary pipeline (throttle / kill pipeline, mud pressurization pipeline, hydraulic pipeline, etc.) of a single drilling riser, and specifically relates to a strap Drilling Riser Fixing Bracket. Background technique [0002] A single drilling riser is one of the key accessories in the entire offshore drilling equipment. After each single is connected up and down, it provides a passage between the underwater blowout unit and the drilling platform (or hull) for marine drilling operations. An important part of the drilling riser system. A single drilling riser is mainly composed of the main body assembly and the external choke / kill pipeline, mud pressurization pipeline, hydraulic pipeline and other auxiliary pipelines and fixed brackets. Among them, the fixed bracket is a fixing device for fixing and supporting auxiliary pip...
