Abstract
Изобретение относится к средствам межскважинных геофизических исследований. Сущность: система состоит из скважинных излучателя (102) и приемника (103), предназначенных для проведения радиоволновых просвечиваний межскважинного пространства, измерительно-управляющего модуля (105), связанного через ретрансляторы (104) с излучателем (102) и приемником (103) посредством оптоволоконного кабеля, и средства позиционирования излучателя и приемника в пространстве. Радиоволновое просвечивание межскважинного пространства проводят, помещая излучатель (102) и приемник (103) в скважины (101). Измерительно-управляющий модуль (105) состоит из компьютеров, выполненных с возможностью выполнения запрограммированных команд управления скважинными приемником и излучателем и обмена данными с ними, настройки антенны упомянутого излучателя в резонанс, выбора и установки рабочей частоты, контроля равномерности проведения радиоволновых просвечиваний, вычисления координат пунктов излучения и приема, формирования массива измеренных значений в заданном формате для их дальнейшей обработки с целью определения удельного электрического сопротивления исследуемых пород, построения трехмерной геоэлектрической карты межскважинного пространства, выделения и локализации электрически контрастных неоднородностей. Технический результат: обеспечение возможности построения трехмерной геоэлектрической карты межскважинного пространства (3D) с повышенной точностью локализации и определения свойств неоднородностей, залегающих в пространстве между излучателем и приемником, в том числе контроля за изменением этих свойств во времени.The invention relates to a means of cross-well geophysical research. Essence: the system consists of a borehole emitter (102) and a receiver (103) intended for conducting radio wave transmissions of the interwell space, a measuring and control module (105), connected through repeaters (104) with a transmitter (102) and a receiver (103) by means of a fiber optic cable, and means of positioning the emitter and receiver in space. Radio wave scanning of the interwell space is carried out by placing the emitter (102) and the receiver (103) in the wells (101). The measuring and control module (105) consists of computers capable of executing programmed commands to control the downhole receiver and transmitter and exchange data with them, adjust the antenna of the said transmitter to resonance, select and set the operating frequency, control the uniformity of radio wave transmissions, calculate the coordinates of points radiation and reception, the formation of an array of measured values in a given format for their further processing in order to determine the electrical resistivity of the studied rocks, build a three-dimensional geoelectric map of the interwell space, highlight and localize electrically contrasting inhomogeneities. EFFECT: provision of the possibility of constructing a three-dimensional geoelectric map of the interwell space (3D) with increased localization accuracy and determination of the properties of inhomogeneities occurring in the space between the emitter and the receiver, including monitoring the change in these properties over time.
