English term or phrase:electromagnetic propagation resistivity logging (EPRL) tool
In addition to serving as part of drilling system, drill bit may be included as part of a LWD system. Drill bit may be capable of logging well, including measuring electromagnetic propagation resistivity properties of the formation, identifying fractures, and identifying and resolving geological features such as bedding planes and their relative dip angle and azimuth.
Drill bit may log well using receiver elements disposed on a raised face of drill bit. In addition, drill bit may also allow for the generation of 3D resistivity profiles around the borehole, which can be represented in graphical form, as well as used for input into complex geological and reservoir models, or as data into complex 3D analysis programs.
The electromagnetic propagation resistivity logging (EPRL) tool comprises one transmitter and a pair of receivers and measures the phase difference and the amplitude ratio (sometimes referred to as attenuation) across two receivers. Generally, the spatial response characteristics of the phase difference and the amplitude ratio can be summarized as follows: the amplitude ratio has large sensing volume and very low resolution than the phase difference.
