现今油田所使用的测斜仪器大部分为磁性测斜仪器。现场施工过程如果不能为仪器提供一个无磁干扰的测量环境就会导致磁干扰现象发生,造成磁场强度和磁倾角偏离当地真实值,最终导致磁性工具面角和测量方位角偏离井底真实值。本论文对磁性测斜仪测量时所受的各种干扰因素进行了分析总结。 Most of the inclinometers currently used in the field are magnetic inclinometers. If the construction process can not provide a non-magnetic interference measurement environment for the instrument, magnetic interference may occur, resulting in deviation of the magnetic field strength and the magnetic inclination from the local real value, resulting in the deviation of the magnetic tool face angle and azimuth from the true bottom hole value. This dissertation analyzes and summarizes all kinds of disturbing factors suffered by magnetic inclinometer.
