摘要:

针对大斜度井环境中的测井响应计算问题,感应测井仪器发射源简化为一系列的磁偶极子,将其在层状地层中产生的电磁场分解成彼此独立的横电波(TE)和横磁波(TM),得到层状地层电磁场含有Bessel函数的解析解。引进高斯积分方法来计算无穷复数域的Bessel函数积分,方便地解决了这类积分问题。根据此方法计算并分析了当前常用的1503型双感应仪器在大斜度井中的测井响应特征,为正确认识和评价大斜度井感应测井资料提供重要依据。

Abstract:

In allution to computation problem of induction logging in drilling technology of deviated wells,the transmitting coils of induction logging instruments are simplified as series of magnetic dipoles,electromagnetic wave is resolved as TE and TM wave in stratified layers,and the analysis results which include integration of Bessel function are deserved in this paper.The integral of Bessel function in infinite complex filed is easily resolved by the Gauss integral method.The responses of commonly used 1503 type dual-induction instrument,simulated and analyzed in this methord,provide a important theory foundation for the evaluation of induction logs.

Key words: stratified media, highly-deviated well, induction logging, Gauss integral method, response computation 
