LWD

 The LWD resistivity-while-drilling system is based on the complete electromagnetic field theory and adopts 2MHz and 400KHz operating frequencies. With the four-transmitter and dual-receiver and dual-transmitter and dual-receiver symmetrical antenna systems, it Measures the amplitude ratio and phase difference of the induced electromotive force of the two receiving antennas during well logging to obtain the formation resistivity; the best symmetrical compensation method is used to eliminate the influence of borehole irregularities and overcome antenna installation errors and circuit drift, thus improving the resistivity measurement accuracy. The application of this device greatly improves reservoir detection efficiency and reduces engineering costs. The orientation and geological parameters are well combined, improving the measurement efficiency of petroleum engineering. It has raised drilling engineering services to a new technical height and provided new technical support for the exploitation of complex geological oil reservoirs.

    Product Features:

    The dual-frequency design and symmetrical compensation measurement eliminates system errors and wellbore effects; the dual-source distance design avoids the influence of instrument eccentricity and dielectric effects; the dual-transmitter and dual-receiver system has shorter zero lengths, which shortens the overall machine size, and reduces the power consumption; it can provide 8 curves of amplitude resistivity and phase resistivity; the scales are clear, eliminating the influence of communication errors; it can provide true amplitude ratio and phase difference information; with the modular design, it enables convenient and quick instrument maintenance; with strong scalability, it has optional battery power supply and Generator power supply; the azimuth gamma can be installed according to customer requirements; and the operation software is visual and the curve display is professional.
