Self-sinking insertion type subsea pipeline mud-entering leakage test device

Abstract

The invention discloses a self-sinking insertion type subsea pipeline mud-entering leakage test device, which comprises a mud surface base plate component, a shunting and control component and a mud-entering and leakage hole component, wherein the mud surface base plate component provides a supporting effect for the shunting and control component and the mud-entering and leakage hole component, the shunting and control component provides fluid connection, shunting and remote control functions, and the mud-entering and leakage hole component provides mud-entering construction and under-mud leakage hole simulation functions. According to the device, a remote control underwater device is adopted, the high-pressure cutting principle and the self-weight sinking principle of jet flow are utilized for mud entering construction, and the device is simple and easy to implement. By setting the aperture sizes and positions of the leakage pipe and the base disc nozzle, the leakage position of the real subsea pipeline is simulated, and the device has multiple functions. The device is simple in offshore construction, visible and controllable in water surface in a mud entering state and capable of being repeatedly used, various different leakage conditions can be simulated through one device, and research on subsea pipeline leakage is facilitated.

Description

technical field [0001] The invention relates to the technical field of exploitation of marine oil and gas resources, in particular to a self-sinking insertion type submarine pipeline mud leakage test device. Background technique [0002] Oil and gas gathering and transportation is an important part of offshore oil and gas development and the "lifeline" of offshore oil and gas production systems. Once the submarine pipeline is damaged, it will cause oil and gas leakage and serious consequences. Not only will the normal production of offshore oil and gas fields be affected, causing huge economic losses; more seriously, oil and gas leakage will cause serious pollution to the marine environment and damage the marine ecology. It can also have negative social impacts. [0003] Studying the leakage behavior of subsea pipelines requires testing, and offshore testing is complex and expensive to construct. Therefore, it is particularly important to study a test device that not only ...
