Pulse electromagnetic sounding of the petroleum- containing layered medium

In this research, propagation of super wide-band pulse in a frequency dispersive medium representing the oil-saturated collector. The capability of their use for geonavigation in techniques of lateral drilling is discussed on the basis of the results of simulation obtained. The complex dielectric constant of oil-saturated rock was calculated on the basis of refraction mixing dielectric model, the oil, sodium chloride solution, methane, quartz and bentonite being contained in each layer. The thin cylindrical vibrator of finite dimensions was used as antenna, being excited by voltage the like one period sinus pulse of nanosecond duration. The time-domain structure of pulse propagation in a plane-layered medium was calculated. Attenuation of power flow pulse reflecting from oil-bearing bed was studied. The gain-frequency characteristic relating to each particular layer was analyzed proving the medium of petroleum collector to operate like a low-pass filter.
