APPARATUS AND METHOD OF IDENTIFYING ROCK PROPERTIES WHILE DRILLING |
摘要 |
Acoustic signals generated by drilling a bore hole with a drill bit are received at sensors placed in the drill string. The acoustic signals received by the sensors are processed, e.g. using a Fourier transform, and a characteristic of the acoustic signals is used to identify lithology, rock strength, presence of oil, presence of gas, change in lithology, or the like.
