江汉石油管理局油田处三矿在原油冷输过程中,出现井口漏油比较严重的情况。经分析,所以出象这种情况,井口回压是一个原因,而抽油光杆被盐水(原油含盐量约385毫克/公斤)迅速腐蚀也是主要原因之一。该矿职工为了解决这个问题,在油管厂的合作下,参考四川省化学研究所磷化防锈的经验,先后在九口井上,试用十根表面多次磷化处理的光杆,获得比较好的防腐效果。

Jianghan Petroleum Administration Oilfield at the Third Department of crude oil in the process of cold storage, there is a wellhead leakage is more serious situation. As a result of this analysis, the reason for this is the wellhead back pressure, which is one of the main reasons for the rapid corrosion of sucker rod by brine (about 385 mg / kg of crude oil). The mine workers in order to solve this problem, in cooperation with the oil pipe plant, reference to the Sichuan Provincial Institute of Chemical phosphating rust-proof experience, successively in nine wells, the trial ten surface phosphating multiple polished rod, get better Antiseptic effect.
