由于天然气属于危险化学品,同时又被纳入危险化学品监管,因此必须按照国家标准《危险化学品重大危险源辨识》(GB18218-2014)中规定的危险物质及临界量确定标准和方法,对天然气处理、储存、运输设施和场所是否属于重大危险源进行辨识.文章介绍了重大危险源辨识的计算方法,以及对苏20、苏25、苏76天然气集气支线、场站存量进行计算的结果.

自2009年我公司在苏里格地区实施水平井以来,虽然完井管柱直径与裸眼段间隙小,但没有发生过通井模拟管串下如顺利,实际下入管串过程中遇阻的情况下入过程中出现泥岩掉块、井底落物、全角变化率大、大肚子井眼等现象会使管柱发生卡钻,始终存在风险,综合以上因素,因此一直将完井作业过程中的井眼清洁作为工作的重中之中,并且通过常规钻具通井、刮削套管壁、下入单铣柱和通井短节来模拟管柱的下入,除工具本身的质量问题外,在几十口水平井施工过程中,未发生通井过程顺利,完井管串下入过程中遇卡的情况,本文通过分析苏**井管柱的力学性能,测出了卡点大致位置,经过起下两次管柱,得出了卡钻的原因.

In recent years,all the oil & gas field Surface construction works of the Oil & Gas Cooperation and Delelopment Company always follow the principle of"the overall deployment,implementation step-by-step,adjustment and optimization in implementation".We conduct project management mode strictly and improve gradually in the process of surface construction.In the process of gas field surface construction management,we get a better way which is more advantageous to prepare the overall deployment,simplified optimization,organization and coordination and construction management of the gas field surface construction to explore the Sulige gas field through constantly practice.This makes the gas field surface construction quality,construction level and the construction speed has been improved significantly.And greatly improve the level of the oil & gas fied Surface engineering construction.
