目前,含有硫化氢的原油产量占总采油量的20～25％。油气介质的腐蚀使油井地面设备、油井井下设备、油气处理装置、注水系统的设备造成破坏。而硫化氢腐蚀使地层水和污水处理系统、注水系统、或向漏失层返注污水系统造成破坏最为严重。油田开发过程中,用注水保持地层压力时,硫化氢在油田开发后期出现。产生硫化 At present, the production of crude oil containing hydrogen sulfide accounts for 20 to 25% of the total oil production. Corrosion of oil and gas causes damage to well equipment, downhole equipment, oil and gas processing equipment, and water injection system equipment. Hydrogen sulfide corrosion, on the other hand, causes the most serious damage to the formation water and sewerage system, water injection system, or return to the sewer system to the lost circulation layer. In the field of oilfield development, hydrogen sulphide appears late in the development of the field as water pressure is used to maintain formation pressure. Sulfated
