“高5转总掺水管线平均腐蚀速率由0.53降到0.02,管线防腐治理见效了。”2017年3月27日,冀东油田陆上采油四区负责人说。近年来,二氧化碳吞吐技术作为冀东陆上作业区的重要增产措施,效果显著。可由于吞吐介质腐蚀性强、管线服役时间长等因素,集输管线腐蚀穿孔问题随之而来,严重影响油气正常生产。
“The average corrosion rate of the 5-turn total water-mixing pipelines was reduced from 0.53 to 0.02, and the pipeline anti-corrosion treatment was effective.” On March 27, 2017, the head of the four areas of onshore oil production in Jidong Oilfield said. In recent years, as an important stimulation measure of Jidong land-based operation area, the technology of carbon dioxide huff and puff has obvious effect. Due to the corrosiveness of the handling medium and the long service life of the pipeline, the problem of corrosion and perforation in the gathering pipeline will follow, seriously affecting the normal production of oil and gas.
