摘要
Abstract
In EH4 work,MN error can cause the apparent resistivity error. Some scholars had deduced the apparent resistivity relative error formula caused by MN error in length. There is a larger deviation between deducting process of the formula and actual work. The influence of EH4 apparent resistivity caused by MN deviation in direction and by both MN error in length and deviation in direction has not been reported. Therefore, this paper adopts theoretical derivation and numeric calculation to study the EH4 apparent resistivity relative error caused by MN error in length, MN deviation in direction and both of them. The research indicates that the EH4 apparent resistivity error increases with MN error; When MN error in length exists, the apparent resistivity relative error caused by negative MN error in length is larger than positive MN error in length caused.关键词
