- 摘要:
- 对大庆某采油厂数个潜油电泵井进行了杂散电流的测试以及该区域土壤腐蚀性的评价。通过对电泵井三相电流负荷对称性的测试,利用100m深的裸眼井监测不同深度处井套管的地下电位变化、不同层深的土壤理化性质,结果表明,检测的个别电泵井中有中等程度的杂散电流存在,同时杂散电流存在的区域也是土壤中含水量、Cl-离子和SO42-离子浓度较高的区域。土壤腐蚀性综合评价结果也显示该区域的土壤腐蚀级别为强腐蚀。
The stray current testing for several submersible pump wells at an oil production plant of Daqing Oilfield and the soil corrosiveness evaluation in that region were performed. Through the testing of three-phase current load symmetry of the submersible pump wells and the underground electric potential variation of casing and soil physical and chemical properties at different well depths by a 100m deep open hole, it was shown that few pump wells exist medium stray current and that the regions having stray current are also the regions of soil containing higher contents of water, Cl-and SO42- . In addition, the comprehensive soil corrosiveness evaluation showed that the soil corrosiveness ranks strong corrosion level.2007,4(4): 46-48 收稿日期：2006-10-16分类号：TE983作者简介：张大伟(1954-),男,黑龙江大庆人,现任温州大学机电工程学院教授,毕业于哈尔滨工业大学材料学专业,工学博士学位,主持完成多项省部局级科研项目,获省部级科技进步二、三等奖各1项,获国家发明和实用新型专利各1项,在国内外发表文章50余篇,有10余篇收入SCI,EI。参考文献：
