Resistivity measurement while drilling system



Core Part For Geosteering Operation


Product Introduction


Product Description


LHE7310A



Speciality


◆ Dual frequency design, symmetrical compensation measurement, eliminate system error and hole effect

◆ The double source distance design avoids the influence of instrument eccentricity and dielectric effect
 
◆ Eight curves of amplitude and phase resistivity are available
 
◆ The high sensitivity calibration is clear and eliminates the influence of communication error
 
◆ True amplitude ratio and phase difference information can be provided
 
◆ Modular design, instrument maintenance convenient and quick

◆ Strong expansibility, battery power supply and generator power supply are optional

◆ According to the requirements of customers can be linked to the azimuth gamma

◆ Communication mode can be M30 and single-bus optional configuration

◆ Operation software visualization, curve display specialization
 

Application


◆ Reservoir geological parameters are added to improve the detection efficiency
 
◆ Good reservoir geological parameters can be obtained during horizontal drilling

◆ In the development of thin reservoir, certain oil recovery is improved
