As the exploitation of oil fields in our country continues for longer periods, the quality of water used for injection deteriorates, and the presence of sulfate-reducing and oxidizing bacteria increases. This leads to severe corrosion and scaling of the pipes, pipelines, and containers used in oil fields, posing a serious challenge to the proper extraction and transportation of oil and gas. A drilling rig repair factory boldly ventured into this field, achieving breakthrough progress in the development and application of anti-corrosion technologies. After hundreds of experiments, they successfully developed a titanium nanocoating for corrosion prevention. This coating boasts excellent corrosion resistance, high temperature tolerance, impact resistance, high strength, good wear resistance, a high surface finish, strong impermeability, and is non-toxic and harmless; moreover, its production process causes no pollution, making it highly suitable for widespread use. A petroleum production plant and others used anti-corrosion pipes coated with \"titanium nano\" polymers in a total of 110 wells, with a combined length of nearly 300,000 meters. It was proven that this approach extended the service life of the injection well pipelines in the oil field by 2 to 3 times, generating economic benefits of nearly 200 million yuan. Due to the special uses of drilling mud and the complex geological conditions, as well as high temperatures and the large amount of chemical additives present in the drilling mud, severe corrosion occurs on the tank bodies, which greatly reduces the lifespan of drilling mud circulation tanks. As a result, the service life of conventional drilling mud circulation tanks is only about 4 years. After coating 128 sets of drilling mud circulation tanks with a “titanium nano” polymer coating for corrosion protection, their service life was also extended by more than twice, saving over 10 million yuan in annual equipment replacement costs. Currently, the losses caused by corrosion and scaling in oil field pipelines are alarming: every year, the damage to numerous pipe strings, pipelines, and containers not only keeps the costs of oil field development high but also severely impacts oil field production. According to a survey conducted on certain oil fields, the direct economic losses resulting from corrosion-induced damage to tubing and pipeline materials in these two oil fields amounted to 140 million yuan and 300 million yuan respectively ； The replacement of pipe strings and pipelines disrupted production, resulting in indirect economic losses of around 1 billion yuan. When extended to oil fields across the country, the losses in this regard amount to as much as 10 billion yuan and 100 billion yuan respectively. If corrosion and scaling issues are not addressed, it is not only difficult to reduce costs, but it also hinders the proper operation of oil and gas field development and production as well as the transportation of oil and gas. The titanium nano anti-corrosion coating developed by a drilling rig repair factory can effectively solve this problem.
