(54) ВЕРТЛЮЖНАЯ ГОЛОВКА(54) SLIDING HEAD

Изобретен-ие отнооитс к технике дл исследовани , газовых и вод ных скважйн на поверхности При применении испытателей лластов, а также дл принудительного перемещени приборов в скважинах со сложными услови ми и Б качестве эле.мента оборудовани дл перфорации с.кважиН.The invention relates to a technique for research, gas and water boreholes on the surface. When using test pieces, as well as forcing the displacement of devices in wells with difficult conditions and B as an element of perforation equipment in the KvazhN.

Известна вертлюжна головка, содержаща затворный узел, переводник, колпак, ствол и Муфту с радиальными ;капала ми 1.A known swivel head containing a valve assembly, a sub, a cap, a barrel and a sleeve with radial drips 1.

Недостатком устройства вл етс иебольша долговечность пробковых кранов, работающих ;В среде абраздавноло буро:вого раствора.The disadvantage of this device is that the large durability of cork cranes working; In the environment of abrasive drilling mud.

Кроме того, головка не позвол ет спускать в скв.ажкну глубин ые приборы.In addition, the head does not allow the deep instruments to be lowered into the well.

Наиболее близким к предлагае:М01му из известных изобретений вл етс в-ертлюжна головка, содержаща1Я ствол с радиальHbiiM каналом, установленную на стволе с возможностью ограниченного осевого перемещени и перекрыти его радиального канала втулку с радиальнЫМ каналом и трем р дами уплотнений, отвод 2.Closest to the proposal: M01mu of known inventions is a rotary head containing a barrel with a radial HbiiM channel mounted on the barrel with the possibility of limited axial movement and blocking its radial channel a sleeve with a radial channel and three rows of seals, retraction 2.

Недостатком известной головки вл етс то, что выполнение втулки гидравлически неуравновешенной вызывает необходиLMocTb изготовлени набора сменных поршней дл охвата диапазона отношений диаметров 1,05-1,30. Кроме того, возможно сам1опроиз.вольное закрытие затвора головки от пульсаций давлени в бурильных трубах при хорошем технологическом состо нии манифольда.A disadvantage of the known head is that making the sleeve hydraulically unbalanced causes the LMocTb to make a set of interchangeable pistons to cover a range of diameter ratios of 1.05-1.30. In addition, it is possible to self-close the head shutter against pressure pulsations in drill pipes with a good technological condition of the manifold.

Целью изобретени вл етс повышение надежности работы .вертлюжной головки.The aim of the invention is to increase the reliability of the swivel head.

Это достигаетс тем, что втулка жестко св зана с отводом и установлена с внешней This is achieved by the fact that the sleeve is rigidly connected to the outlet and installed with the outer

10 стороны ствола, пр|Ичем последний снабжен блоком привода втулки, л-становленным на :1одп1ипнике.10 side of the barrel, pr | Ichem last equipped with a sleeve drive unit, l-mounted on: 1podipnik.

На фиг. 1 изображена конструкци вертлюжной головки, иродолыный разрез; на FIG. 1 shows the design of a swivel head, and a weedoid incision; on

15 фиг. 2 и 3 - схемы дистанционного управлени телескоп)1ческим затвором вертлюжной головки.15 of FIG. Figures 2 and 3 show the remote control schemes of a telescope with a single bolt of a swivel head.

Вертлюжна головка состоит из ствола / с радиальным каналом, на который гер20 метично посажена втулка 1 с радиальным ка алом и боковы|М отводом 5. Дл фиксации втулки при транспортировке служит хомут 4. В верхнюю часть ствола ввертываетс колпак 5, боковое отверстие которого нредназначено дл образцового манометра. The swivel head consists of a shaft / with a radial channel on which sleeve 1 with a radial canal and side | M branch 5 is hermetically seated. To fix the sleeve during transport, serve a clamp 4. In the upper part of the barrel a cap 5 is screwed in, the side opening of which is designed for model gauge.

25 На колпаке установлен |блок 6 привода втул:ки дл укладки троса .ручной Л ебедки. Чтобы при вращении ствола блок был пенодв:ижен , он установлен на подщипник 7. 25 On the cap is installed | block 6 drive bushing: ki for laying the cable. Manual L winch. So that when the barrel rotates, the block is penodv: izhen, it is mounted on the support 7.

Claims

30 To ensure explosion-proof, the head is equipped with a ball bearing 8. FoviOBKa is screwed to drill pipes with an impeller 9. The sleeve has three rows of seals 10. The barrier on the sleeve is placed between the medium: NI (MI and the outermost seals, flow radial the channel — between the radiami and the extreme | mi. upper seals. The telescopic shutter control is carried out in the following order. After screwing the head with the drill pipe 11, laid on the receiving IMOCT. wasp "on the side of the head. Then the movable hook 13 of the hand winch 14 is inserted into the loop, and its cable 15 (placed in the chute of the block 6. After screwing the pipe with the bu (the tool | Ment), lower the IB initial position before packing The fixed winch hook is fastened by a reliable base, for example, the rotor 16. The well is packaged when the telescope slide is open while the sleeve 2 is in the lower position (Fig. 2). The shutter is closed by winding the cable onto the hand winch drum and moving the sleeve to the top position (Fig. 3). When rotating drill pipes, the position of the block does not change as it is connected to the cap | M in a non-rigid manner. In order for 4TOi6bi to open the telescopic shutter, it is enough to wind the cable from the drum of the manual winch and the sleeve under the weight of the wellhead pipe will move to the lower position. In the case of low dead weight, the Lebe; Dku is applied to the same purpose. In order to force the device to move in a well with difficult conditions, for example, when pa, if there is a horizontal section of the profile, it is necessary to unscrew the cap 5 from the swivel head and install a lubricator instead of it. The forced movement of the instrument in the well is carried out by | 0 ° F or 1 overpressure in the lateral outlet 3 at the open position of the gate. For attachment and swivel heads, the cap 5 is also turned off as a perforating valve and the lubricator is installed. The sub 9 is expanded by an additional flanged sub, with which the head is attached to the fittings. The eco nomic effect of the use of a swivel head is due to the fact that the cost of testing wells with abnormally high reservoir pressure is lower compared to testing by the compressor method. existent swivel heads. Claims of the invention: Swiveling head containing a trunk with a radial channel, mounted on the trunk with the possibility of a limited axle displaced and blocking its radial channel sleeve with a radial channel .m and three rows of seals, retraction, about m and h It is iC that, in order to increase the reliability of operation, the sleeve is rigidly connected to the outlet and installed on the outer side of the barrel, the latter is provided with a sleeve actuator mounted on the bearing.
