井地电位监测技术现场试验结果对比分析

Comparative analysis of field test results of well-ground potential monitor technology.

文章简要介绍了井地电位测量技术的方法原理和现场施工步骤,重点针对三套不同井地电位监测系统在喇嘛甸油田北西块6区的喇6-233和喇6-P2325两口井的现场试验结果进行了对比分析发现,监测结果的一致性较高;再结合三套监测系统的主要技术指标表明,发射电流的大小以及选择合适的发射频率对井地电位监测的精度、探测深度起到比较关键的作用。

This paper introduces the methodological principle of the well-ground potential monitoring technique and on-site construction procedure briefly,and comparatively analyses two well field test results by three set well-ground potential surveillance system in La6-233 well and La6-p2325 well of area 6 of the north west block in Lamadian oilfield. Consistency of monitoring result is well. Three set monitoring system technical description shows that emission current magnitude and the selected appropriate transmission frequency play key role in well-ground potential monitor accuracy and investigation depth.
