Multi-Propagation Resistivity

Electromagnetic resistivity logging technology accurately obtains formation resistivity by measuring the propagation characteristics (phase difference and amplitude attenuation) of electromagnetic waves during oilfield operations. Its core functions include geological location, fluid identification, reservoir evaluation, and engineering risk early warning.

**Multi-Depth Resistivity Detection**

By emitting 2MHz/50kHz electromagnetic waves and utilizing phase difference/amplitude attenuation measurements, resistivity curves at eight different detection depths (0.1-5m range) can be obtained, enabling fine radial evaluation from intrusion zones to undisturbed formations.

**Azimuth Imaging Capability**

Eight-sector azimuth gamma and resistivity imaging technology can identify formation interfaces (such as oil-water interfaces and shale interlayers) in real time, significantly improving geological steering accuracy.

**Dynamic Environmental Correction**

A patented dynamic compensation algorithm eliminates interference from instrument eccentricity and mud intrusion (especially oil-based mud) on measurements, ensuring the reliability of high resistivity formation data.
