Изобретение относитс к нефтегазодобывающей промышленности и примен етс при креплении нефт ных и газовых скважин секци ми обсадных колонн.The invention relates to the oil and gas industry and is used in casing of oil and gas wells with casing sections.
Известно устройство дл спуска секций обСадных колонн.содержашее корпус.состо щий из муфты и воронки и полый вал с левой резьбой IJiA device for lowering sections of casing columns containing a housing consisting of a coupling and a funnel and a hollow shaft with a left-hand thread IJi is known.
Недостатком этого устройства вл етс необходимость разгрузки части обсадной колонны дл отворота по левой резьбе, что в глубоких скважинах сделать практически невозможно.A disadvantage of this device is the necessity of unloading a part of the casing string for a lapel along the left-hand thread, which is practically impossible to do in deep wells.
Наиболее близким техническим решением из известных вл етс устройство дл спуска секций обсадных колонн, содержащее корпус, крышку, упорный подшипник, полый вал со umoHKai m и соединительную втулку 2.The closest technical solution known is a device for lowering casing sections, comprising a housing, a cover, a thrust bearing, a hollow shaft with amoHKai m, and a connecting sleeve 2.
Однако в случае подвески секций обсадных колонн на цементном камне с выходом головы секции в необсаженный ствол устройство нельз примен ть без замены или ремонта резьбовой детали.However, in the case of suspension of casing sections on cement stone with an outlet of the section head into the open hole, the device cannot be used without replacing or repairing the threaded part.
Цель изобретени - увеличение его долговечности при работе в необсаженной части ствола скважины.The purpose of the invention is to increase its durability when operating in the open hole part of the wellbore.
Цель достигаетс тем, что устройство снабжено концетрично расположенным относительно его оси подпружиненным предохранительным стаканом.The goal is achieved by the fact that the device is equipped with a spring-loaded safety cup located concentrically with respect to its axis.
На фиг. 1 показано предлагаемое устройство при спуске и цементировании секции; на фиг. 2 - устройство в транспортном положении при подъеме после агсюеднненн секщш.FIG. 1 shows the proposed device during the descent and cementing section; in fig. 2 - the device is in a transport position when lifting after auguated section.
Устройство содержит корпус 1 с внутренней левой резьбой полый вал 2 со шпонками 3 и ограничителем 4, соединительную втулку 5 с наружной левой резьбой, крьшпсу 6 и упорный подшипник 7. Внутри корпуса 1 подвижно в осевом направлении и кондентрично с внутренней поверхностью корпуса 1 и осью устройства установлен предохранительный стакан 8, поджимаемый снаружи в сторону предохранительной втулки 5 пружиной 9.The device includes a housing 1 with an internal left thread, a hollow shaft 2 with keys 3 and a stop 4, a connecting sleeve 5 with an external left thread, a collar 6 and a thrust bearing 7. Inside the housing 1 is movable in the axial direction and is constant with the inner surface of the housing 1 and the axis of the device installed safety Cup 8, pressed from the outside towards the safety sleeve 5 by a spring 9.
Устройство работает следующим образЬм.The device works as follows.
