Abstract
Изобретение относится к области геофизики и, в частности, к поиску и оконтуриванию углеводородных залежей без бурения скважин. Цель изобретения - повышение достоверности и точности идентификации месторождений. Заявленный способ предусматривает облучение исследуемого геопрофиля с мобильной платформы электромагнитной волной на двух фиксированных частотах fи fизмерение на этих частотах в точках геопрофиля напряженности электрического поля Eи Eпри включенных передатчиках, а затем напряженности электрического поля Eи Eпри отключенных передатчиках, определение для каждой частоты разностного сигнала E=E-Eи E=Е-E, вычисление для каждой точки геопрофиля отношения β=E/Eи определение координат точек измерения геопрофиля глобальной системой позиционирования. По аномальным значениям параметра β и на основе данных глобальной системы позиционирования судят о наличии и границах месторождения. Число используемых фиксированных частот может быть более двух. Устройство согласно изобретению содержит установленные на мобильной платформе передатчики (1), (3) и приемники (2), (4), образующие две приемопередающие пары, блок (5) сопряжения, навигационный приемник (6), оконечное устройство (7), блок (8) управления и два устройства (8) и (9) коммутации. Все упомянутые приемники и передатчики оснащены антеннами с возможностью их пространственной ориентации. Антенны, кроме антенны приемника (6), установлены на фиксированной высоте подвеса. Блок (5) сопряжения по входу связан с навигационным приемником (6) и устройством (10) коммутации, а по выходу - с оконечным устройством (7). Передатчики (1), (3) расположены на платформе по отношению к приемникам (2), (4) на расстоянии, удовлетворяющем условию: X/λ=X/λ=const,The invention relates to the field of geophysics and, in particular, to the search and delineation of hydrocarbon deposits without drilling wells. The purpose of the invention is to improve the reliability and accuracy of identification of deposits. The claimed method provides for irradiation of the investigated geophilic from a mobile platform with an electromagnetic wave at two fixed frequencies f and f measurements at these frequencies at the geoprofile points of the electric field E and E with the transmitters turned on, and then the electric field E and E with the transmitters off, determining the difference signal E = E for each frequency -E and E = E-E, calculating the ratio β = E / E for each geoprofile point and determining the coordinates of geoprofile measurement points by the global positioning system Nia. The abnormal values of the parameter β and on the basis of the data of the global positioning system are judged on the presence and boundaries of the field. The number of fixed frequencies used can be more than two. The device according to the invention comprises transmitters (1), (3) and receivers (2), (4) installed on a mobile platform, forming two transceiver pairs, an interface block (5), a navigation receiver (6), a terminal device (7), a block (8) controls and two switching devices (8) and (9). All mentioned receivers and transmitters are equipped with antennas with the possibility of their spatial orientation. Antennas, except the receiver antenna (6), are installed at a fixed suspension height. The interface unit (5) is connected with the navigation receiver (6) and the switching device (10), and with the output device - with the terminal device (7). Transmitters (1), (3) are located on the platform with respect to receivers (2), (4) at a distance satisfying the condition: X / λ = X / λ = const,
