电法和电磁法是油田开发和开采地球物理学家必不可少的工具,因为地层电阻率与储层流体饱和度和温度密切相关。不幸的是,在已开发的油田中高度的人为噪声限制了地面电法的使用。而钢套管的普遍使用又限制了在已完井中井下仪器的使用。结果,除了裸眼测井外,在勘探阶段完成后,油田中通常不使用电法。 Electrical and electromagnetic methods are indispensable tools for oil and gas exploration and production geophysicists because formation resistivity is closely related to reservoir fluid saturation and temperature. Unfortunately, the high level of man-made noise in developed fields limits the use of terrestrial electrical methods. The widespread use of steel casing limits the use of downhole equipment in completed wells. As a result, in addition to open-hole logging, electrical methods are generally not used in the field after the exploration phase is completed.
