CT2—1缓蚀剂是四川省天然气研究所研制的高效油溶性缓蚀剂.适用于天然气井、输气管线、压气站等装置;对H_2S、CO_2等酸性气体造成的均匀腐蚀、局部腐蚀均有显著的缓蚀作用;对高强度钢的硫化物应力腐蚀破裂和低强度钢的氢脆破坏亦有较好的缓蚀作用.在四川省油气田已广泛应用.大庆油田没有单一的天然气生产井,天然气主要以油田伴生气开采出来,气体中H_2S含量较低,在70～150ppm范围内,随着三次采油的开发,H_2S含量逐年增高,然而在油气加工中均未设置脱硫装置.油田伴生气中CO_2
CT2-1 corrosion inhibitor is an efficient oil-soluble corrosion inhibitor developed by Sichuan Institute of Natural Gas, applicable to natural gas well, gas pipeline, compressor station and other devices. Homogeneous corrosion and local corrosion caused by H2S, CO2 and other acid gases Has a significant inhibition; high strength steel sulfide stress corrosion cracking and low strength steel hydrogen embrittlement also have a good corrosion inhibition in Sichuan Province has been widely used in oil and gas fields. There is no single natural gas production wells in Daqing , The natural gas is mainly produced by associated gas in the oilfield, and the content of H 2 S in the gas is relatively low. Within the range of 70-150ppm, with the development of the tertiary oil recovery, the H 2 S content increases year by year, but no desulfurization device is installed in the oil and gas processing.
