摘要
PDC钻头在给钻井工作带来高钻速、高效益、较高井身质量的同时,由于其特殊的破岩机理,导致常规录井方法在使用PDC钻头时受到了限制。总结PDC钻头对岩屑录井、钻时录井和荧光录井的影响,提出相应的改进措施,并探讨在使用PDC钻头时的一些新的录井技术,通过这些改进可以实现录井结果的真实可靠。
Well drilling with PDC bit has produced high drilling velocity,good benefit and higher quality of well structure.Meanwhile,because of the special rock breaking mechanism,the traditional logging methods can not be used effectively.This article analyses the influence to traditional logging methods such as cuttings logging,drilling time logging and fluorescence logging when using PDC bit,at the same time sums up some new logging methods.With these new methods we can get the logging results correctly.
