我国已开发的油气不同程度地含有硫化氢气体,它是一种剧毒、容易致人死亡的可燃气体,具有刺激性和窒息性气味,低浓度接触仅有呼吸道及眼的局部刺激作用,高浓度时全身作用较明显,表现为中枢神经系统症状和窒息症状。一旦发生井喷,将导致灾难性的悲剧,不仅严重威胁着人们的生命安全,造成环境的恶性污染,同时对金属设备、工具及用具也将造成严重的腐蚀破坏。因此,在含有硫化氢井的施工中,必须采取相应的对策,利用测井技术与测试工艺的有效结合,把对环境的污染和设备、工具的损耗降至最低。
Hydrocarbons, which have been developed in our country, contain hydrogen sulfide gas to varying extents. It is a highly toxic and easily fatal combustible gas with irritating and asphyxiating odor. Only low respiratory and eye irritation results in low concentration exposure. High Concentration of the role of the more obvious systemic, manifested as central nervous system symptoms and asphyxia symptoms. In the event of a blowout, it will lead to a catastrophic tragedy that not only seriously threatens people’s lives and causes vicious environmental pollution but also causes serious corrosion damage to metal equipment, tools and appliances. Therefore, in the construction of wells containing hydrogen sulfide, we must take appropriate countermeasures, the use of logging technology and test the effective combination of technology, the environmental pollution and equipment, tools to minimize the loss.
