Abstract
The invention relates to the technical field of oil field oil well drilling and production, in particular to a hydraulic tubing anchor. The hydraulic tubing anchor comprises an upper connector, a center pipe, an upper piston, a cone, a slip, a slip seat, lower pistons, a horse thread ring, a horse thread barrel, a lower connector and a spring. The upper connector is fixed to the upper portion of the center pipe, the spring is located between the upper piston and the upper connector and connected to the center pipe in a sleeving mode, the lower portion of the slip is matched with the slip seat, the periphery of the slip seat is connected with the upper portion of the horse thread barrel, and the horse thread ring is arranged between the lower piston and the horse thread barrel. A floating block is arranged between the lower pistons, inclined threads matched with the horse thread barrel are arranged on the horst thread ring and the floating block respectively, the floating block is connected with the lower pistons through shear pins, and the lower connector is connected with the lower portions of the lower pistons. The device has a one-way locking function, that is, in the upward moving process of the slip, the lower portion is fixed through the inclined threads, and the clamp is effectively prevented from loosening.
Description
Technical field
The present invention relates to oilfield drilling and production technology field, particularly relate to a kind of hydraulic tubing anchor.
Background technology
In petroleum recovery operations, in order to prevent oil pipe from wriggling up and down and rotating, causing oil pipe eccentric wear, even loss parts, usually adopting the method for installing tubing anchor to come grappling and protection oil pipe.Described tubing anchor is arranged on below flow string usually, be a kind of for the production of or service shaft in mainly play the downhole hardware of anchoring string effect.
The grappling function of existing tubing anchor mainly utilizes the relative motion of top connection and slips when transferring central tube, forces slips outwards to open, and the slip insert on outside slips is clamped near the inwall of jail at sleeve pipe, the position of fixed center pipe in sleeve pipe.When releasing grappling, above carry central tube, make top connection depart from slips, slips resets by the spring leaf on tubing anchor, makes the slip insert on slips depart from internal surface of sleeve pipe, thus removes grappling.As Chinese patent discloses a kind of tubing anchor, the patent No. 200410039801.5, this kind of tubing anchor can only lean on ambient pressure to promote when slips is fixing, if when ambient pressure reduces, owing to there is not locking function, slips can be caused to loosen, and then cause grappling failure.
Summary of the invention
The object of the invention is to the deficiency overcoming above-mentioned technology, and a kind of hydraulic tubing anchor is provided, locking can be realized in the process suppressed, prevent slips to lose efficacy.
The present invention for achieving the above object, by the following technical solutions: a kind of hydraulic tubing anchor, comprises top connection, central tube, upper piston, cone, slips, slip spider, lower piston, gingival cyst of mucous gland in the newborn ring, gingival cyst of mucous gland in the newborn cylinder, lower contact, spring, described top connection is fixed on the top of described central tube, described spring is between described upper piston and described top connection and be socketed on described central tube, liquid pass hole is provided with between described central tube and described upper piston, described cone is connected with the bottom of described upper piston, the bottom of described cone coordinates with described slips, the bottom of described slips coordinates with described slip spider, the outer shroud week of described slip spider is connected with described gingival cyst of mucous gland in the newborn cylinder top, described lower piston is placed between described gingival cyst of mucous gland in the newborn cylinder and described central tube, described gingival cyst of mucous gland in the newborn ring is placed between described lower piston and described gingival cyst of mucous gland in the newborn cylinder, rocker piece is provided with between described lower piston, described gingival cyst of mucous gland in the newborn ring and rocker piece are respectively equipped with the helical teeth tooth coordinated with described gingival cyst of mucous gland in the newborn cylinder, described rocker piece is connected with described lower piston by shear pin, described lower contact is connected to the bottom of described lower piston.Relative to prior art, this device is with one-way locking function, and namely slips moves up in process, bottom is fixed by helical teeth tooth, effectively prevents slips from loosening, central tube entrance pressure power, it is up that pressure promotes upper piston, Compress Spring, is with movable cone up simultaneously, the slip spider of pressure promotion simultaneously drives slips up, and the meshing gingival cyst of mucous gland in the newborn ring of gingival cyst of mucous gland in the newborn cylinder, realizes setting, carry central tube on during deblocking, cut off pin, gingival cyst of mucous gland in the newborn ring moves down, slips moves down, and realizes deblocking.
Preferably, rocker piece activity space is provided with between described lower piston and described gingival cyst of mucous gland in the newborn cylinder.
The invention has the beneficial effects as follows: relative to prior art, this device is with one-way locking function, and namely slips moves up in process, bottom is fixed by helical teeth tooth, effectively prevents slips from loosening, central tube entrance pressure power, it is up that pressure promotes upper piston, Compress Spring, is with movable cone up simultaneously, the slip spider of pressure promotion simultaneously drives slips up, and the meshing gingival cyst of mucous gland in the newborn ring of gingival cyst of mucous gland in the newborn cylinder, realizes setting, carry central tube on during deblocking, cut off pin, gingival cyst of mucous gland in the newborn ring moves down, slips moves down, and realizes deblocking.
