Description

Дл  измерени  толщины глинистой корки на стенках скважины примен ют устройства, опускаемые в скважину на каротажном кабеле.To measure the thickness of the mudcake on the borehole walls, devices are used that are lowered into the well on the wireline cable.

Устройства подобного рода не обеспечивают достаточно высокой точности измерени .Devices of this kind do not provide a sufficiently high measurement accuracy.

Дл  устранени  указанного недостатка предлагаетс  выполн ть устройство в виде башмака, прижимаемого рессорой к степке скважины имеющего щель, в которую проходит круглый пож, закрепленный на качающемс  коромысле, и омического, датчика .сопротивлений, св занного с осью коромысла и заключенного в заполненную маслом герметическую камеру.To eliminate this drawback, it is proposed to carry out a device in the form of a shoe pressed by a spring to a steppet of a well that has a slit, into which a circular fire passes, mounted on a rocker arm, and an ohmic resistance sensor connected to the axis of the rocker and enclosed in an oil-filled pressure chamber. .

На чертеже изображена схема пред.чагаемого устройства. Устройство смонтировано на бащмаке /, который прижимаетс  при помощи рессоры 2 к стенке скважины и скользит по ней при подъеме и опускан;п1 каротажного кабел . Башмак имеет щель, в которую входит подвижной круглый нож 3, установленный на качающемс  коромысле 4. С осью 5 коромысла св зан обычный омический датчик соиротивлений, расположенный в герметичной наполненной маслом камере 6.The drawing shows a diagram of the preceding device. The device is mounted on the bagmake /, which is pressed by means of a spring 2 against the borehole wall and slides along it when lifting and lowering; n1 of the logging cable. The shoe has a slot into which a movable round knife 3 is inserted, mounted on a rocker arm 4. The conventional ohmic air sensor, which is located in a sealed oil-filled chamber 6, is connected to the shaft 5 of the arm.

При движении башмака вдоль стенки скважины нож 3 прорезает глинистую корку, выступа  из башмака на то или иное рассто ние; при этом омический датчик сопротивлений фиксирует толщину прорезанной корки. Показанн  датчика, измер ющего толщину глинистой корки, передаютс  по каротажному кабелю на регистрирующий прибор.When the shoe moves along the borehole wall, the knife 3 cuts through the mudcake, protruding from the shoe at one or another distance; at the same time, an ohmic resistance sensor records the thickness of the cut crust. The sensor shown that measures the thickness of the mudcake is transmitted via a logging cable to a recording instrument.
