在开采含硫化氢和二氧化碳等腐蚀成分的石油或天然气时,所用的开采设备必须采用能耐腐蚀破坏的特种钢材制造。在开采的介质中含有湿硫化氢气体、而且设备部件处于抗应力作用的情况下,钢材往往容易产生硫化氢腐蚀开裂,使井口设备受到严重损害。根据国外一些公司的产品样本、说明书、杂志等技术资料的介绍,现将耐腐蚀自喷井井口装置零部件材 In the exploitation of petroleum or natural gas containing corrosive components such as hydrogen sulphide and carbon dioxide, the mining equipment used must be made of special steel that is corrosion resistant. In the mining medium containing wet hydrogen sulfide gas, and equipment parts in the role of anti-stress, the steel is often prone to hydrogen sulfide corrosion cracking, the wellhead equipment was severely damaged. According to some foreign company’s product samples, brochures, magazines and other technical information, now corrosion-resistant since the wellhead equipment parts and components
