(54) ПРИБОР ДЛЯ ИССЛЕДОВАНИЯ СКВАЖИН(54) WELL RESEARCH DEVICE

1one

Изобретение относитс к нефтедобывающей промышленности, а именно к устройствам дл исследовани глубиннонасосныкскважин .FIELD OF THE INVENTION The invention relates to the oil industry, namely, devices for exploration of deep well pumps.

Известен прибор дл определени глубинц скважин, содержащий опускаемый- на тросе груз 11A known device for determining the depth of the wells, containing a weight-11 lowered on a cable.

Известен также прибор дл исследовани скважин, срлержаедий опускаемый на проволоке корпус. Also known is a well testing apparatus, a stranded body lowered onto a wire.

Прибор позвол ет производить-за мер уровн жидкости, глубины,подвески насоса и забо скважины 121.The device allows production of liquid level, depth, pump suspension and bottom hole 121.

Недостатком известного прибора вл етс его сложна конструкци .The disadvantage of the known device is its complex structure.

Целью изобретени вл етс упрощение конструкции. . .The aim of the invention is to simplify the design. . .

Поставленна цель достигаетс тем, что корпус выполнен в виде полого цилиндра с верхним конусншл наконечником и упорами на внутренней поверхности , причем внутри цилиндра установлен опускаемый на проволоке цилиндрический груз и поршень с отверстием дл центрировани груза, ,при этом поршень установлен с возможностью продольного перемещени между упорами.The goal is achieved by the fact that the casing is made in the form of a hollow cylinder with an upper cone tip and stops on the inner surface, with a cylindrical weight lowered onto the wire and a piston with a hole for centering the load inside the cylinder, with the piston mounted for longitudinal movement between the stops .

На чертеже схематично изображен прибор дл исследовани скважин/ разрез.The drawing shows a schematic of a well survey / incision tool.

Прибор состоит из груза с петлей 2, установленного внутри полого цилиндра-кожуха 3 с конус шли посгщочннм наконечником 4 поршн 5, имеющего .возможность двигатьс продольно между кольцевыми упорами 6 и 7,The device consists of a load with a loop 2 installed inside the hollow cylinder-casing 3 with a cone coming with a sharp tip 4 of the piston 5, which has the ability to move longitudinally between the ring stops 6 and 7,

С целью использовани Прибора в. насосно-компрессорных трубах разного диаметра конусный наконечник может In order to use the Appliance c. tubing pipes of different diameters cone tip can

10 быть выполнен сменным с продольной щелью 8 шириной не менее диаметра проволоки примен емой при исследовании скважин/ и наворачиватьс на резьбу , нарезанную на внешней поверхнос15 ти верхнего торца цилиндра.10 to be made interchangeable with a longitudinal slit 8 with a width not less than the diameter of the wire used in the well survey and to be threaded on the thread cut on the outer surface of the upper end of the cylinder.

Прибор работает следующим образом.The device works as follows.

При производст е текущего ремонта скважин, после подъема вставного скважинного. насоса/ прибор с помощью With the production of routine repair of wells, after lifting the in-hole well. pump / device using

20 аппарата Яковлева опускаетс в скважину через насосно-компрессорные трубы . Прибор при встрече с уровнем жидкости -останавливаетс , благодари воздушной подушке внутри полого ци25 линдра 2, нат жка проволоки уьгеньшаетс и по ее длине суд т о глубине уровн жидкости в скважине.20, the Yakovlev apparatus is lowered into the well through tubing. The device, when it encounters a fluid level, stops, thanks to the air cushion inside the hollow cylinder 2, the wire tension decreases and the depth of the fluid level in the well is judged by its length.

Claims

After immersing the device in the fluid of its movement. For a short time, the unit stops and, during this period of time, the device acquires its original form and continues to move from no to 3. Upon reaching the insertion pump landing unit, the device is inserted into it, and by loosening the wire tension and its length, the suspension depth of the pipes is judged. At the same time, a hollow cylinder with a cone landing tip b completely covers the spring bark, and the weighed load 1 from the rest of the instrument assembly lowers itself down to the bottom and to relax the wire, its length is set to the bottom hole. proceed to lift the load 1. In this case, the load, the income to the piston, is centered by it and is directed inside the cylinder. He, the income with the piston to the stop ring, rises with the cylinder to the surface. As a result, in the zone of the spring core of the plug-in pump, the wire finds the device from the inside-cylinder casing during the entire process of measuring and lifting, which prevents its engagement and the occurrence of an emergency situation. The use of the instrument on the polyslach ensures the complexity of the exploration of deep-well wells without lifting axial-compressor pipes, which makes it possible to carry out measurements of the depth of pipe suspension and the bottom hole depth in one descent. All this reduces the number of triggers for research. Claims of the invention A well testing apparatus comprising a housing lowered onto a wire, characterized in that, in order to simplify the construction, the housing is designed as a hollow cylinder with an upper conical tip and stops on the inner surface, a cylindrical weight lowered onto the wire and a piston mounted inside the cylinder with a hole for centering the load, while the piston is mounted for longitudinal movement between the stops.
