1. Способ геонавигации наклонно-направленных скважин в пластах малой мощности, включающий определение электрического сопротивления пластов, пересеченных скважиной, путем пропускания импульсов тока через генераторную катушку и регистрации ЭДС переходных процессов в приемной катушке, отличающийся тем, что определение электрического сопротивления пород проводят на двух радиусах измерения, изменяя расстояние между генераторной и приемной катушками, сохраняют направление бурения при близких значениях, полученных на разных радиусах измерения сопротивления, и изменяют направление бурения при получении отличающихся друг от друга значений сопротивления, причем направление бурения меняют в зависимости от знака разности измеренных сопротивлений и геологии региона.1. The method of geosteering directional wells in low-power formations, including determining the electrical resistance of the formations crossed by the well by passing current pulses through the generator coil and registering the EMF of the transient processes in the receiving coil, characterized in that the electrical resistance of the rocks is determined at two radii measurements, changing the distance between the generator and receiver coils, preserve the direction of drilling at close values obtained at different radii of measurement rhenium resistance, and change the direction of drilling in the preparation of differing resistance values, wherein the direction of drilling vary in dependence on the sign of the difference in the measured resistances and geology of the region. 2. Устройство геонавигации наклонно-направленных скважин в пластах малой мощности, содержащее немагнитную металлическую трубу, встроенную в компоновку низа бурильной колонны, генераторную и приемную катушки, источник импульсного тока, соединенный с генераторной катушкой, и приемную катушку, соединенную с блоком управления, отличающееся тем, что введена вторая генераторная катушка, соединенная со вторым источником импульсного тока и размещенная на определенном расстоянии от первой генераторной катушки, катушки размещены внутри немагнитной металлической трубы на немагнитном каркасе, источники импульсного тока соединены в свою очередь с блоком управления, связанным через канал связи с пультом управления технологическим процессом навигации ствола скважины.2. A device for geosteering directional wells in low-power formations, comprising a non-magnetic metal pipe integrated in the bottom of the drill string, a generator and receiver coil, a pulse current source connected to the generator coil, and a receiver coil connected to the control unit, characterized in that a second generator coil is introduced, connected to a second pulse current source and placed at a certain distance from the first generator coil, the coils are placed inside a nonmagnet of a total metal pipe on a non-magnetic frame, the pulse current sources are in turn connected to a control unit connected via a communication channel to a control panel of the technological process for navigating the wellbore.
