【摘要】：隨著經(jīng)濟的快速發(fā)展,我國的能源結(jié)構(gòu)已經(jīng)發(fā)生了重大變化,天然氣等清潔能源在能源消費結(jié)構(gòu)中所占比例越來越高。四川是天然氣開發(fā)利用大省,資源儲量豐富,勘探開發(fā)歷史超過50年,已建成了覆蓋全省各大中小城市的天然氣集輸管網(wǎng)。近年來,隨著城鎮(zhèn)建設(shè)和輸氣管網(wǎng)建設(shè)速度加快,四川省輸氣管道安全隱患數(shù)量增加,管道事故呈現(xiàn)多發(fā)狀態(tài)。為了消除輸氣管道安全隱患,遏制管道事故發(fā)生,確保人民群眾生命財產(chǎn)安全,本文以問題導(dǎo)向和事故案例分析為基礎(chǔ),對四川省輸氣管道安全管理現(xiàn)狀進行了分析,并吸收國外先進輸氣管道管理經(jīng)驗,提出了有針對性的對策措施。研究具有一定的現(xiàn)實意義。通過對四川省輸氣管道安全生產(chǎn)現(xiàn)狀分析以及對近年來典型輸氣管道事故案例的分析和事故統(tǒng)計,本文得出了以下結(jié)論：第一,四川省輸氣管道主要事故類型是：腐蝕、施工及材料缺陷、第三方破壞、自然災(zāi)害等。第二,四川輸氣管道事故致因變化趨勢是：輸氣管道鋪設(shè)速度加快的時期都是第三方破壞影響最嚴重的時期；設(shè)計和施工問題導(dǎo)致的管道泄漏主要發(fā)生在管道運行的前期,腐蝕和材質(zhì)問題導(dǎo)致的管道泄漏主要發(fā)生在管道運行的中后期,安全管理和第三方破壞貫穿于管道運行的整個過程；天然氣管道的穩(wěn)定期為35年,超過35年的管道事故處于多發(fā)易發(fā)狀態(tài)。第三,四川省輸氣管道安全管理存在的問題有：企業(yè)管道完整性管理體系還不完善、企業(yè)現(xiàn)場安全管理不到位、管道第三方破壞呈現(xiàn)上升趨勢、政府監(jiān)管主體責任未明確和落實、輸氣管道和城鄉(xiāng)建設(shè)在發(fā)展規(guī)劃上存在矛盾。四川省輸氣管道安全管理問題具有普遍性,本文提出的對策有助于進一步加強輸氣管道安全管理,確保輸氣管道安全穩(wěn)定運行。結(jié)合國外先進經(jīng)驗和國內(nèi)實際,作者提出了加強管道完整性管理、加強企業(yè)現(xiàn)場安全管理、堅決遏制第三方破壞、進一步明確政府監(jiān)管責任、加強城鎮(zhèn)規(guī)劃和管道建設(shè)之間的協(xié)調(diào)等對策措施。這些措施一定程度上能夠解決輸氣管道安全管理中存在的問題,具有一定的參考價值。
[Abstract]:With the rapid development of economy, the energy structure of our country has changed greatly, and the proportion of clean energy such as natural gas in the energy consumption structure has become higher and higher. Sichuan is a big province of natural gas exploitation and utilization with rich resources and a history of exploration and development for more than 50 years. It has built a natural gas gathering and transportation network covering all the large and medium-sized cities in the province. In recent years, with the speeding up of urban construction and gas pipeline network construction, the number of hidden dangers of gas pipeline safety in Sichuan Province has increased, and pipeline accidents have occurred frequently. In order to eliminate the hidden dangers of gas pipeline safety, contain pipeline accidents and ensure the safety of people's lives and property, this paper analyzes the present situation of gas pipeline safety management in Sichuan Province based on problem-oriented and accident case analysis. At the same time, some countermeasures are put forward to absorb the foreign advanced gas pipeline management experience. The research has certain realistic significance. Based on the analysis of the current situation of gas pipeline safety in Sichuan Province and the analysis and statistics of typical gas pipeline accidents in recent years, this paper draws the following conclusions: first, the main types of accidents in Sichuan gas pipeline are corrosion, corrosion and corrosion. Construction and material defects, third party damage, natural disasters, etc. Second, Sichuan gas pipeline accidents cause changes in the trend is: the speed of gas pipeline laying is the most serious period of third-party damage; The pipeline leakage caused by design and construction problems mainly occurs in the early stage of pipeline operation, and the pipeline leakage caused by corrosion and material problems mainly occurs in the middle and late stage of pipeline operation. Safety management and third party destruction run through the whole process of pipeline operation; Gas pipeline stability period is 35 years, more than 35 years of pipeline accidents are prone to occurrence. Third, the problems of Sichuan gas pipeline safety management are: the enterprise pipeline integrity management system is not perfect, the enterprise site safety management is not in place, and the pipeline third party damage is on the rise. The main responsibilities of government supervision are not clear and implemented, and there are contradictions in development planning between gas pipelines and urban and rural construction. The problem of gas pipeline safety management in Sichuan Province is universal. The countermeasures proposed in this paper are helpful to further strengthen the safety management of gas pipeline and ensure the safe and stable operation of gas pipeline. Combined with foreign advanced experience and domestic practice, the author proposes to strengthen pipeline integrity management, strengthen on-site safety management of enterprises, resolutely curb third party damage, and further clarify the responsibility of government supervision. Strengthen the coordination between urban planning and pipeline construction and other countermeasures. To some extent, these measures can solve the problems existing in the safety management of gas pipeline, and have certain reference value.
