Description
Technical field
This utility model belongs to Oil & Gas Storage technical field, particularly relates to a kind of Oil & Gas Storage pipeline with leakage monitoring function.
Background technology
Oil & Gas Storage is to connect production of hydrocarbons, process, distribute, sell the tie of all links, and it mainly includes, and oil gas field collection is defeated, long-distance transmission pipeline, store and load and unload and city distributing system etc..The Tenth Five-Year Plan (2001-2005) has planned the " construction of the larger hydrocarbon storage and handling facilities such as West-east Gas engineering, transnational oil and gas pipes engineering and national strategic oil storage.Nearly 7000 kilometers of the natural gas line the most implemented (gross investment about 65,000,000,000 yuan), the transnational oil gas long-distance transmission pipeline 16000 kilometers in proposal.
Within 2014, China Petroleum Pipeline operation mileage reaches 6196 kilometers, and oil and gas pipes technology and equipment production domesticization acquires a great achievement, and indicates that China's oil gas backbone's pipe network ensures that general layout basically forms, and the sustainable development for China's economy contributes.
Within 2014, CNPC persistently advances resource, market, the enforcement of internationalization three great strategy, carry forward vigorously China's oil gas energy strategy passage construction, completing pipeline welding mileage 2000 kilometers, 33 major projects such as Central Asia natural gas line C line and Hu Bao Hubei Province processed oil pipeline are constructed and put into operation.So far, China's Land petroleum pipeline total kilometrage, more than 120,000 kilometers, covers 31 provinces, autonomous regions and municipalities of China and special administrative region, and nearly 1,000,000,000 people are benefited, and has played important function in terms of ensureing national energy security.
On November 9th, 2014, the supply framework agreement signature of Sino-Russian western line, Sino-Russian natural gas cooperation obtains historical breakthrough.Before this, the line natural gas purchase and sale agreement signature of Sino-Russian east, China's northeast inlet natural gas strategic corridor construction thus raises the curtain.
In newly operated project, Central Asia natural gas line D line becomes bright spot.This pipeline will open up China's import Central Asia natural gas second channel, also be the important energy source project of " one with a road " strategy.
In project in construction; middle remote natural gas line is constructed and put into operation completely; NORTHWEST CHINA, northeast, southwest and marine four big oil and gas import passages are got through; do not simply pull on China's economic development, advanced transition and upgrade and environmental conservation, ensured energy security, and drive national economic development along the line and the lifting of people's livelihood quality.
On May 31st, 2014, Central Asia natural gas line C line is gone into operation.On November 20 the same year, western three line west sections are open to traffic, and will be stood westwards a line and two wires, capital, Shan system, your line downstream transport middle by centre halfback from the natural gas in the Central Asia and Xinjiang natural gas from coal.The Yangtze River Delta, Pearl River Delta, Circum-Bohai Sea and Sichuan-chongqing Region several hundred million common people will be benefited.
Currently, I crosses one of main mode of oil gas transport is exactly pipeline transportation, and oil and gas pipes construction is paid much attention to concerning national energy security, party and state leaders.The leakage of oil and gas pipes not only causes any property loss, and environment also can cause severe contamination, and long oil and gas pipeline occurs the reason leaked varied, but substantially can be divided into:
(1) corrosive pipeline: overcoat is aging, cathodic protection was lost efficacy, and the corrosion that inner-walls of duct is caused by the corrosion composition of the Korrosionsmedium corrosion that causes pipeline outer wall and transmission medium.
(2) corollary failure: owing to the natural disaster such as earthquake, landslide and climate change make pipeline generation buckling deformation cause stress rupture.
(3) damage from third-party: the theft of lawless person destroys, workmen operates against regulations, the destruction that barbarous construction causes.
(4) pipeline self-defect: include pipeline welding mass defect, pipe connection portion position poor sealing, do not design the reasons such as pipeline expansion joint, material.Gas oil pipe leakage causes huge economic loss, and can damage environment, have a strong impact on the healthy of subjective reflection and life security not only to production, unit of operation.
Need badly and leakage monitor is set on Oil & Gas Storage pipeline, thus monitor the generation of leakage in time, reduce loss.
Summary of the invention
