Description
Изобретение относитс к вибрацион ному просвечиванию Земли.This invention relates to the vibrational transmission of the Earth.
Известен способ вибрационной сейсморазведки , включающий возбуждение и регистрацию вибросигналов, в котором возбуждение сигналов ведетс в режиме параметрического излучени , когда из-за нелинейных детектирующих свойств среды несуща высокочастотна компонента вибросигнала быстро затухает, а распростран етс низкочастотна компонента, вл юща с orrfбающей исходного сигнала t lНедостатком известного способа вл етс небольшой коэффициент полезного действи параметрического преобразовани сейсмической энергии и трудности управлени волновым полем в дальней зоре излучател .A known method of vibration seismic exploration, including excitation and recording of vibration signals, in which signals are excited in a parametric emission mode, when, due to the nonlinear detection properties of the medium, the carrier high-frequency component of the vibration signal quickly fades, and the low-frequency component propagates as the source signal or the Low signal The known method is a small coefficient of efficiency of parametric transformation of seismic energy and the difficulty of controlling Yeni wave field in the far-sighted radiator.
S.S.
Известен акже способ вибросейсмической разведки, включающий формирование в зонах излучени и приема сейсмических сигналов, регистрацию сигналов в зоне приема н последующую обработку полученных данных, причем дл образовани и усилени полезного сигнала излучени формируютс Р и S врлны, а в зоне приема - Р волны 2.Also known is the method of vibroseismic reconnaissance, which includes the formation of seismic signals in the emission and reception zones, the recording of signals in the reception area and the subsequent processing of the received data, while P and S are formed to form and amplify the useful radiation signal, and in the reception area - P wave 2.
Недостаток такого способа заключач етс в необходимости дополнительных энергетических затрат дл формировани пол Р и S волн в зоне излучени и необходимости йспользовать еще один источник вибросигналов в зоне приема.The disadvantage of this method lies in the need for additional energy costs for the formation of the field P and S waves in the radiation zone and the need to use another source of vibrosignals in the reception zone.
Наиболее близким к предлагаемому вл етс способ вибросейсмической разведки, включающий возбуждение The closest to the present invention is a method of vibroseismic reconnaissance, including the excitation of
10 вибратором сигнала с частотой, соответствуницей стабильному экстремуму частотной характеристики пол микросейсм и регистрацию возбужденного сигнала ц 3}.10 with a signal vibrator with a frequency corresponding to the stable extremum of the frequency response of the field of microseisms and recording of the excited signal of η 3}.

Недостатком этого способа вл етс снижение эффективности излучени вибросигналов в периоды спада уровн пол микросейсм.The disadvantage of this method is a reduction in the radiation efficiency of the vibrosignal during periods of decay of the field of microseisms.
Цель изобретени - увеличение ин20 тенсивности излучаемого сигнала и повышение глубинности разведки.The purpose of the invention is to increase the intensity of the emitted signal and increase the depth of intelligence.
Поставленна цель достигаетс тем, что в способе вибросейсмической разведки , включающем возбуждение вибра25 тором сигнала с частотой, соответствующей стабильному экстремуму частотной характеристики пол микросейсм и регистрацию возбужденного сигнала, при фОЕ 1ировании возбуждаемого сигна30 па дополнительно используют частотThis goal is achieved by the fact that in the method of vibroseis reconnaissance, which includes excitation of a signal with a vibrator with a frequency corresponding to a stable extremum of the frequency characteristic, the field of microseisms and recording of the excited signal when the excitation signal is 30OF, additional frequencies are used
