Description
Изобретение от;:осгггс к центратору дл обеспечени со(.1С;:осгй труб над устьем скважины установки стыков под сварку труб, примен емых 1з горном деле ппи бурении скважины на нефть и газ.Invention from;: Osgggs to a centralizer to provide co (.1С;: Osgi pipes over the wellhead to install joints for pipe welding, used in the mining business of drilling oil and gas wells.
Известен иечтратор обсадных Tpv6, станавливасм ):й :;ад устьем скважины, содержащий iLiKTy с ;-1евмоцилиндром и коро .мысло.м, .крон1итейн и челюсти i4.A well-known casing Tpv6 strainer (stanavavavsm): y:; hell hole containing iLiKTy with; -1ev cylinder and box. Ton. M. Quadrant and jaw i4.
Однако такой центратор сложен и не обеспечивает точного центрировани труб.However, such a centralizer is complex and does not provide accurate centering of the pipes.
Известеп также центратор обсадных труб, состо щий из корпуса, толкател с разменденными на нем центрирующилн к)-лачками с ролика.чи, обоймы .медных прокладок , пневмоцилиндров, пружин возврата , наконечника подвода воздуха и чеки дл задержки ентратора в трубе при отсоединении наконечника 2.Also known is a casing centralizer consisting of a body, a pusher with centering knuckles from a roller.ch, holders of copper gaskets, pneumatic cylinders, return springs, an air supply tip, and checks to delay the hub in the pipe when disconnecting the tip 2 .
Недостаток известного центратора - сложность и ненадежность работы иневмосистемы в св зи с бьстрьш износом уплотнительных резиновых колец, что ведет к стравлива .ию воздуха из центратора. Воздух может поступать в зону свариваемого стыка и сдувать защитную среду газа, чтоThe disadvantage of the known centralizer is the complexity and unreliability of the inevism system in connection with the rapid deterioration of the sealing rubber rings, which leads to the release of air from the centralizer. The air can enter the zone of the welded joint and blow off the protective gas environment, which
ведет к ооразованию некачественного стыка и обрыву колонны в скважину.leads to the formation of poor-quality butt and breakage of the string into the well.
Цель изобретени - упрощение конструкции центратора.The purpose of the invention is to simplify the design of the centralizer.
Цель достигаетс тем, что предлагаемый центратор снабжен рычагами, установ/1енными на толкателе и щарнирно св занными между собой.The goal is achieved by the fact that the proposed centralizer is equipped with levers mounted on the pusher and hinged together.
На фиг. 1 изображен центратор; на фиг. 2 и 3 - разрезы А-А и Б-Б фиг. 1.FIG. 1 shows a centralizer; in fig. 2 and 3 - sections A-A and BB of FIG. one.
.Центратор состоит из корпуса 1, четырех центрирующих р дов кулачков 2, обоймы медных прокладок 3, чеки Ц, двух центральных стержней 5 и 6, JB радиальные выточки которьз х заведены плечики центрирующих кулачков 2. Стержни 5 и 6 взаимосв заны посредством плавающего стакана 7, внутри которого наход тс пружины 8 и 9, разделенные кольцевым выступом стержн 5. На толкателе 10 установлены два щарнирно св занных между собой рычага 11 с роликами 12. В верхней части корпуса установлена пружина возврата 13.The hub consists of a body 1, four centering rows of cams 2, a clip of copper gaskets 3, checks C, two central rods 5 and 6, JB radial grooves which are formed by the hanger of centering cams 2. The rods 5 and 6 are interconnected by means of a floating glass 7 , inside which there are springs 8 and 9, separated by an annular protrusion of the rod 5. On the pusher 10 there are two pivotally connected levers 11 with rollers 12. In the upper part of the body there is a return spring 13.
Центратор работает следующим образом.The centralizer works as follows.
На тросу центратор опускаетс в трубу 14 и удерживаетс на ее кромке рычагамиOn the cable, the centralizer is lowered into the tube 14 and held on its edge with levers
