近年来,随着录井技术的不断发展,国内外越来越多的探井和开发井,在钻井过程中使用PDC钻头,由于PDC钻头在使用过程中钻压小、钻速快,在钻井过程中被越来越广泛的使用。由于PDC钻头牙齿细小,所破碎的岩屑颗粒小,有的PDC岩屑接近粉末状,这就给岩屑的识别带来难度和困难。本文介绍了在使用PDC钻头的条件下,如何更有效与准确进行岩屑识别与处理的可行方法。
In recent years, along with the continuous development of logging technology, more and more exploration wells and development wells at home and abroad use PDC bit during drilling. Because PDC bit has small bit-pressure during drilling and high drilling speed, In more and more widely used. Due to the tiny teeth of PDC bit, the broken debris particles are small, and some PDC cuttings are close to powder, which makes it difficult and difficult to identify cuttings. This article describes possible ways to identify and process cuttings more efficiently and accurately using PDC bits.
