Description

Известные приборы с применением отдельно датчика на пружине или пружины дл  прижима всего прибора к стенке скважины не обеспечивают надежного прижима датчиков в скважинах, осложненных кавернами как малого, так и большого размера.Known devices using a separate spring sensor or springs to hold the entire device against the borehole wall do not reliably press sensors in wells complicated by cavities of both small and large size.

В описываемом приборе, с целью повышени  надежности прижима выносного датчика в кавернах различных размеров, в скважинном приборе применены два независимых прижимных устройства, действующих в противоположные стороны.In the described instrument, in order to increase the reliability of the clamping of the remote sensor in cavities of various sizes, two independent clamping devices acting in opposite directions were used in the well instrument.

Изображенный на чертеже прибор состоит из корпуса /, с измерительной частью 2 прибора вверху, большой пружины 3, малой пружины 4 с закрепленным на ней датчиком 5 и направл юш,им хвостовиком 6 прибора.The device depicted in the drawing consists of a body /, with the measuring part 2 of the device at the top, a large spring 3, a small spring 4 with a sensor 5 fixed on it and directed by the tool shank 6 by it.

При спуске прибора в скважину больша  пружина 3 прижимает весь прибор к стенке скважины, а мала  пружина прижимает к стенке скважины выносной датчик. Применение двух независимо действующих пружинных устройств увеличивает надежность прижима выносного датчика как в малых кавернах, благодар  небольшой длине пружины с выносным датчиком, так и в больших кавернах в результате увеличени  хода прижимных устройств, равного сумме ходов большой и малой пружины .When the device is lowered into the well, the large spring 3 presses the entire device to the well wall, and the small spring presses the remote sensor to the well wall. The use of two independently acting spring devices increases the reliability of clamping the remote sensor both in small caverns, due to the small length of the spring with the remote sensor, and in large caverns as a result of an increase in the pressure of the pressing devices equal to the sum of the strokes of the large and small spring.

Предмет изобретени Subject invention

Прибор радиоактивного каротажа с выносным датчиком, отличаю ш и и с   тем, что, с целью повышени  надежности прижима выносного датчика в камернах различных размеров, в скважинном приборе применены два независимых прижимных устройства, действующих в противоположные стороны, первое из которых - большее - служит дл  прижима всего прибора, а второе - меньшее прижимает датчик, закрепленный на нем.A radioactive logging device with a remote sensor is distinguished by the fact that, in order to increase the reliability of the remote sensor clamping in chamber chambers of various sizes, two independent clamping devices operating in opposite directions are used in the borehole device, the first of which is clamping the entire device, and the second - less presses the sensor attached to it.
