本文介绍了一种无机锌盐化台物——川设6—1钻井液除硫剂,根据试验结果,论证了它对钻井液的除硫效率和对钻具的防腐效果;并与两种进口的钻井除硫剂进行了对比。现场试验结果表明:川设6—1除硫反应快、效率高、成本低,使钻井液中的硫化氢浓度很快降低到安全界限,从而防止了钻具和套管的硫化物应力腐蚀和失重腐蚀,大大延长了钻具的使用寿命,并避免了钻井操作人员的硫化氢危害。
In this paper, a kind of inorganic zinc salinization station, Chuanjian 6-1 drilling fluid desulfurizer, is introduced. Based on the test results, the desulfurization efficiency of drilling fluid and the anticorrosive effect on drilling tools are demonstrated. Imported desulfurization agent was compared. Field test results show that: Sichuan Chuan 6-1 sulfur quick reaction, high efficiency, low cost, the concentration of hydrogen sulfide in drilling fluid quickly reduced to the safety margin, thus preventing the drill pipe and casing sulfide stress corrosion and Loss of weight corrosion, greatly extending the service life of drilling tools, and to avoid the hazards of hydrogen sulfide drilling operators.
