摘要
随钻电磁波电阻率测井的影响因素包括井眼、仪器偏心、井轴与地层相对夹角、各向异性、围岩、电介质和泥浆侵入等。通过不同的模型可以研究随钻电磁波电阻率测井的响应,对于随钻电磁波电阻率测井的正反演模拟与解释都有重要的指导意义,本文以贝光休斯MPR仪器为模拟仪器,介绍了利用XFDTD方法模拟井下情况所得到的这些环境因素影响的实验结果。
The influencing factors of LWD electromagnetic resistivity logging include borehole,eccentricity of tool,separation angle between well axle and formation,anisotropy,surrounding rock,dielectric medium and mud invasion,etc.The response of LWD electromagnetic resistivity well logging can be studied with different models,which is of significance to the forward and inverse simulating and interpretation.Taking Baker ?Hoghes tool as the simulating tool,the paper introduces the experimental result of the environmental influencing factors through simulating downhole condition with XFDTD method.
