Problems solved by technology

However, there are few studies on the mechanical properties of coiled tubing when it is lowered into the ocean riser, so it is necessary to design a device for analyzing the mechanical properties of the coiled tubing when it is lowered into the ocean riser, so as to guide the later application of coiled tubing in marine engineering

Abstract

The invention relates to a deep-sea pipe-in-pipe mechanical transfer characteristic analysis experiment device, in particular to a device for analyzing mechanical transfer characteristics in the process of coiled tubing tripping into a deep-sea riser. When in experiment, a chain hoist 6 is opened, and an injection test assembly 9 clamps simulated coiled tubing to perform injection operation under the traction effect of a steel wire rope 7. The injection force of the simulated coiled tubing can be obtained by reading parameters of a tension compression sensor on the injection test assembly 9 in the injection process, the injection depth of the simulated coiled tubing can be obtained by reading parameters of a displacement sensor on the injection test assembly 9, the stress of the end of the simulated coiled tubing can be obtained by reading parameters of a pressure sensor inside a pipe end fixing test assembly 2, and the stress of a simulated riser can be obtained by reading parameters of a strain gauge on a pipe-in-pipe system 20. Finally obtained results can be used for analyzing mechanical characteristics of the coiled tubing tripping into the marine riser.

Description

(1) Technical field [0001] The invention relates to a deep-sea pipe-in-pipe mechanical transfer characteristic analysis experiment device, in particular to a device for analyzing the mechanical transfer characteristic of a coiled tubing lowered into a deep-sea riser. (2) Background technology [0002] In offshore oil and gas engineering, if traditional drill pipes are used for oil and gas well washing, drilling and other operations, the operator needs to connect the drill pipes one by one. This is not only inefficient, but also takes a long time to operate. Therefore, coiled tubing is widely used in the world for offshore oil and gas fields such as well washing, drilling, workover, completion, mechanical oil recovery, logging and perforation, and oil and gas transportation. Its advantages are: the coiled tubing is a continuous tubular high-strength, low-carbon alloy steel coiled tubing string, which can be as long as 7620m, and can be wound on a reel to achieve continuous un...
