随钻多深度多频率电阻率测井设备关键技术研究
Research on key technology of multi-depth and multi-frequency resistivity tool while drilling
摘要
Abstract
Given the pressing demand for comprehensive formation information during geosteering while drilling,as well as the critical challenge of independently developing a multi-depth and multi-frequency electromagnetic wave resis-tivity logging tool while drilling,this study focuses on the key technologies for the development of a multi-depth and multi-frequency electromagnetic wave instrument while drilling.The structure and operational principles of a multi-depth antenna array are presented,alongside a theoretical analysis of its multi-frequency antenna tuning net-work.A dual-frequency tuning network and drive circuit module have been designed to optimize the antenna trans-mitting efficiency and transmitting energy within the multi-depth antenna array at specific operating frequencies.Practical tests demonstrated that the multi-depth antenna array exhibited excellent consistency,with actual antenna transmitting tuning responses and power levels meeting design requirements.This study laid an important foundation for the independent development and application of the multi-depth and multi-frequency electromagnetic wave resis-tivity instrument while drilling.关键词
