Background technology:
The super short radius horizontal well technology is a new technology that develops rapidly recent years; Get out the down hole tool system of the production runner that reaches 30～50 meters from former well short radius in the reservoir; Can effectively increase drainage area, be mainly used in old well production potential tapping transformation and new well completion.In super short radius horizontal well technology work progress, in order to prevent guide-track groove play up and down, be employed in the guide-track groove lower end and connect positioning anchor, prevent oil pipe and guide-track groove play up and down.At present the positioning anchor that uses of oil field mainly adopts and prevents down the structure of scurrying to have the risk of scurrying on the tubing string, causes the construction of super short radius horizontal well technology to be failed.
The utility model content:
The technical problem that the utility model will solve provides a kind of bidirectionally anchoring locator, and this device has been realized the location drilling tubing string and sprayed tubing string that string is moving up and down in work progress to prevent tubing string.Overcome existing positioning anchor and only can prevent to scurry under the tubing string, had the deficiency of scurrying risk on the tubing string.
The technical scheme that the utility model is taked is: a kind of bidirectionally anchoring locator comprises top connection, piston, fluid cylinder, ball seat, upper center tube, fishing sleeve, lower center tube, interior pipe, the pawl spring of giving up, packing element upper pressing cap, packing element axle, packing element, cone, bi-directional slip and lower contact; The top connection lower end is stuck in the step place of fluid cylinder and seals through sealing ring; The upper center tube upper side has aperture; Upper center tube is threaded with top connection, and piston places in the annular space of upper center tube and fluid cylinder, and seals with upper center tube, fluid cylinder respectively through sealing ring; Ball seat is suspended in the upper center tube through the ball seat shear pin, and through sealing ring and upper center tube sealing; Internal Pipe Thread is connected on the ball seat, and the pawl spring upper end of giving up is threaded with upper center tube; Lower center tube is enclosed within on the pawl spring of giving up, and its outer end car has the stopping button, and the stopping ring set is buckled end at the stopping of lower center tube; The deblocking ring set places stopping ring lower end on lower center tube, and is suspended on the fishing sleeve through the deblocking pin; Fishing sleeve upper end car has the button of salvaging, and is fixed on the lower center tube through seat offset nail, and the packing element axle is fixed on the fishing sleeve lower end through shear pin; Packing element upper pressing cap, packing element are sleeved on the packing element axle, and cone is enclosed within on the lower center tube, and are threaded with the packing element axle; The bi-directional slip outside has the reverse symmetry cat's paw, and there is the conical surface inboard, matches with the conical surface angle of cone, places the slip groove of lower contact; Lower contact is threaded with lower center tube.
The beneficial effect of the utility model is: the utility model has been owing to adopted reverse symmetry cat's paw's bi-directional slip, thereby has and prevent tubing string moving function of string up and down in work progress.
Description of drawings:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Accompanying drawing is the structural representation of the utility model.
The specific embodiment:
Shown in accompanying drawing; A kind of bidirectionally anchoring locator comprises top connection 1, ball seat shear pin 2, piston 3, fluid cylinder 4, ball seat 5, upper center tube 6, fishing sleeve 7, seat offset nail 8, stopping ring 9, deblocking ring 10, deblocking pin 11, lower center tube 12, interior pipe 13, the pawl spring 14 of giving up, shear pin 15, packing element upper pressing cap 16, packing element axle 17, packing element 18, cone 19, bi-directional slip 20, lower contact 21, support ring 22 and holder cap 23; Top connection 1 upper end is connected on the oil pipe through tubing thread; Through oil pipe design attitude in the well; The lower end is stuck in the step place of fluid cylinder 4 and through the sealing ring sealing, upper center tube 6 upper side have aperture, and upper center tube 6 is threaded with top connection 1; Piston 3 places in the annular space of upper center tube 6 and fluid cylinder 4, and seals with upper center tube 6, fluid cylinder 4 respectively through sealing ring; Ball seat 5 is suspended in the upper center tube 6 through ball seat shear pin 2, and through sealing ring and upper center tube 6 sealings; Interior pipe 13 is threaded on the ball seat 5, and the threaded connection place uses staple to fix, and prevents the rotation dropout; Pawl spring 14 upper ends of giving up are threaded with upper center tube 6, and the threaded connection place uses staple to fix, and prevent that rotation from threading off; Lower center tube 12 is enclosed within on the pawl spring 14 of giving up, and its outer end car has the stopping button, and stopping ring 9 is enclosed within the stopping of lower center tube 12 and buckles end; Deblocking ring 10 is enclosed within on the lower center tube 12, places stopping ring 9 lower ends, and is suspended on the fishing sleeve 7 through deblocking pin 11; Fishing sleeve 7 upper end cars have the button of salvaging, and are fixed on the lower center tube 12 through seat offset nail 8, and packing element axle 17 is fixed on fishing sleeve 7 lower ends through shear pin 15; Packing element upper pressing cap 16, packing element 18 are sleeved on the packing element axle 17, and cone 19 is enclosed within on the lower center tube 12, and are threaded with packing element axle 17; Bi-directional slip 20 outsides have the reverse symmetry cat's paw, and there is the conical surface inboard, match with the conical surface angle of cone 19, place the slip groove of lower contact 21; Lower contact 21 is threaded with lower center tube 12, and the threaded connection place uses staple to fix, and prevents the rotation dropout.
