Abstract
The invention provides an oil pipe drainage anchor which is used in oil fields, and aims at solving the problem that a conventional oil pipe drainage anchor cannot realize halfway pressure testing in an oil pipe descending process. The oil pipe drainage anchor is composed of a conventional oil pipe anchor, and a hollow shear pin which is arranged in a hollow pipe, wherein a hydraulic communication hole is plugged by the hollow shear pin in the process of going down in a well, and an oil pipe pressure-testing oil pipe anchor cannot realize anchoring at this time; when the oil pipe is laid down and an oil rod is drawn downward, a plunger shears the hollow shear pin in the process of passing through the drainage anchor, a hydraulic channel is opened, and the oil pipe anchoring can be realized. Compared with the other oil pipe drainage anchors, the oil pipe drainage anchor has the advantages that not only are the functions of oil drainage and anchoring obtained, but also a halfway pressure testing function in the oil pipe descending process is obtained at the same time, so that the labor strength of workers is relieved, negative influences to production from a plurality of uncertain factors are avoided, and the efficacy is improved.
Description
Technical field
The present invention relates to a kind of oil field downhole tool, particularly relate to a kind of can midway pressure testing oil draining anchoring device of oil pipe.
Background technology
Oil draining anchoring device of oil pipe is downhole tool conventional in sucker rod pumping technique, and on-the-spot Application comparison is extensive.Can oil draining function be completed, decreasing pollution on the one hand, improve the working environment of workman, the grappling of oil pipe can also be realized on the other hand, improve pump efficiency, energy conservation.In the actual production of oil field, cause whole time tubing string by situation about again tripping out for avoiding indivedual tubing thread poorly sealed, often need the oil pipe pipe section pressure test of going into the well also known as midway pressure testing.And the on-the-spot most oil draining anchoring device of oil pipes adopted do not possess midway pressure testing function.Chinese patent (application number) 2005201277569 discloses a kind of Oil pipe anchoring and oil leakage device, though this Oil pipe anchoring and oil leakage device reliably can realize draining and the grappling function of oil pipe, but, the operation of midway pressure testing is very numerous and diverse, when using in the oil well that some stratum water absorbing capacity is stronger, even cannot realize midway pressure testing, have impact on the scope of application and the effect of this instrument.
Summary of the invention
The present invention is just to provide one can overcome the deficiencies in the prior art, provides one can realize reliable grappling and draining, and operate very easy to realize in lower Tubing During Running can the oil draining anchoring device of oil pipe of midway pressure testing simultaneously.
The technical solution adopted in the present invention is: the oil draining anchoring device of oil pipe be made up of central tube, piston, anchor watt etc., the hydraulic communication through hole of central tube arranges a pin, one end and the hydraulic communication through hole of this pin match, combine with hydraulic communication through hole by modes such as screw thread, interference fit, rubber sealing or bondings, by the shutoff of hydraulic communication through hole, when midway pressure testing, because pin is by the shutoff of hydraulic communication through hole, fluid power cannot be delivered to plunger shaft and promote piston stroking upward, can not complete grappling action; After oil pipe has been gone into the well, when the oil pump plunger piston of going into the well or the special joint that is connected on sucker rod are by this draining anchorage device, pin is cut off, be opened by the fluid power passage of shutoff, fluid power can enter plunger shaft through passage and promote piston stroking upward, complete the grappling action of oil pipe, object of the present invention is achieved.
Preferably, described oil draining anchoring device of oil pipe, there is the blind hole of an ecto-entad vertically its pin inside.
Preferably, described oil draining anchoring device of oil pipe, its pin ends has a cavity.
Preferably, described oil draining anchoring device of oil pipe, its pin is nonmetals.
The outstanding advantages that this invention has compared with prior art is: the function not only with draining and grappling, also there is the midway pressure testing function in lower Tubing During Running simultaneously, alleviate the labour intensity of workman, avoiding many uncertain factors to producing the adverse effect brought, improve effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of this invention; Fig. 2 is a kind of structural representation partial enlarged drawing of embodiment; Fig. 3 is the structural representation partial enlarged drawing of another kind of embodiment.
In accompanying drawing: [1] central tube; [2] piston; [3] pin; [4] plunger shaft; [5] cavity; [6] blind hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated, and provide a kind of preferred forms.
As shown in Figure 2: pin [3] can adopt nonmetallic moulding, left end has blind hole [6], cavity [5] is had in right-hand member, adhesive can be adopted to be bonded together between left end and central tube [1], play sealing and fixing effect, its effect of the cavity [5] of left end is the equivalent density reducing pin, can automatically float after pin is cut off, can not enter in wear-resistant, cause oil well pump cisco unity malfunction and lost efficacy.When plunger or special joint pass through, pin [3] is cut off, and blind hole [6] becomes through hole; As shown in Figure 3, pin is solid, and sealing is by " O " shape sealing ring, and after pin [3] is cut off, the left-half of pin is pushed cavity [5] by fluid power, is opened by intercommunicating pore.
Operating principle of the present invention is: when lower oil pipe pressure test, the hydraulic communication through hole due to pin shutoff on central tube, and the fluid power in central tube cannot be delivered on piston, therefore can not grappling during pressure testing; When oil pipe is behind precalculated position, enter sucker rod down again, when the oil pump plunger piston of sucker rod lower end or the special joint that is connected on sucker rod are by draining anchorage device, pin is cut off by plunger, fluid power passage is opened, fluid power in central tube can enter plunger shaft by blind hole and promote piston stroking upward, and complete grappling, object of the present invention is achieved.
The above embodiments are only the embodiment of the present invention on common a kind of draining anchorage device, lean on the oil pipe anchoring apparatus of hydraulic drive to be combined, by arranging the embodiment of shear pin shutoff fluid power intercommunicating pore all within protection scope of the present invention with other.
Claims (4)
1. the oil draining anchoring device of oil pipe be made up of central tube, piston, anchor watt etc., it is characterized in that: on the hydraulic communication through hole of central tube, be provided with pin, one end and the hydraulic communication through hole of this pin match, combine with hydraulic communication through hole, by the shutoff of hydraulic communication through hole by modes such as screw thread, interference fit, rubber sealing or bondings.
