Abstract
The utility model relates to an anchor fluke non-falling hydraulic anchor which comprises an anchor body, a sealing ring, an anchor fluke and a spring, wherein an outer anchor fluke hole and an inner anchor fluke hole are arranged on the anchor body, the diameter of the outer anchor fluke hole is smaller than the diameter of the inner anchor fluke hole, a reducing shoulder is formed between the outer anchor fluke hole and the inner anchor fluke hole, a reducing shoulder is arranged on the anchor fluke, the diameter of the outer end of the anchor fluke is smaller than the diameter of the inner end, the anchor fluke is installed into the outer anchor fluke hole from the anchor body, and the anchor fluke is matched with the outer anchor fluke hole; the sealing ring is installed between the anchor fluke and the outer anchor fluke hole; the spring is sheathed on the anchor fluke, the spring stays in the inner anchor fluke hole, the inner end face of the spring is located on the reducing shoulder on the anchor fluke, and the outer end face of the spring is located on the reducing shoulder formed between the outer anchor fluke hole and the inner anchor fluke hole; and one reducing shoulder is arranged in the anchor fluke hole, one reducing shoulder is arranged on the anchor fluke, the anchor fluke is installed into the anchor fluke hole from the anchor body, and the reducing shoulder in the anchor fluke hole can block the reducing shoulder on the anchor fluke. The anchor fluke can only move within a certain range and can not fall outwards, the falling of the anchor fluke to clamp a pipe column can be prevented, and the engineering accidents of an oil well are avoided.
Description
Technical field
The utility model belongs to the tubing string anchoring device that oil well is used, and is the anchor fluke hydraulic anchor that do not come off.
Background technology
During oil well oil-pumping, fluid column is loaded with on oil pipe and sucker rod to change with the oil pumper up-down stroke and replace transfers, and the oil pipe elongation is shortened, and causes the oil pumping pump efficiency low, the output minimizing, and tubing bending minimizing application life, alternately the capacity of exerting all one's strength causes the oil pipe well of threading off.For fear of the appearance of the problems referred to above, the anchor fluke hydraulic anchor that do not come off has been used at the scene, is used for fixedly oil pipe, prevents oil pipe extension.During the oil-water well construction technology that has, cause that in order to prevent the tubing string play downhole tool such as packer damages, also will be at instrument upper joint hydraulic anchor.But the anchor fluke on the existing hydraulic anchor outside in fills, and anchor fluke can come off during use, causes that the anchor fluke card keeps a grip on, and causes the oil well engineering accident.
Summary of the invention
The purpose of this utility model is the design anchor fluke hydraulic anchor that do not come off, and makes the anchor fluke on its hydraulic anchor can be spacing, prevents the anchor fluke card tubing string that comes off.
The purpose of this utility model is achieved in that and comprises the anchor body, sealing ring, anchor fluke, spring, outer anchor fluke hole is arranged on the anchor body, interior anchor fluke hole, the diameter in outer anchor fluke hole is less than the diameter in interior anchor fluke hole, form the reducing shoulder between outer anchor fluke hole and the interior anchor fluke hole, the reducing shoulder is arranged on the anchor fluke, anchor fluke outer end diameter is less than the inner end diameter, anchor fluke is packed in the anchor body in the outer anchor fluke hole, anchor fluke has with outer anchor fluke hole and cooperates, between anchor fluke and the outer anchor fluke hole sealing ring is installed, spring housing is contained on the anchor fluke, and spring is in the interior anchor fluke hole, spring inner end seat is on the reducing shoulder on the anchor fluke, on the reducing shoulder that spring outer face seat forms between anchor fluke hole and the interior anchor fluke hole outside.
The beneficial effects of the utility model are: the reducing shoulder is arranged in the anchor fluke hole, the reducing shoulder is arranged on the anchor fluke, anchor fluke is packed in the anchor body in the anchor fluke hole, reducing shoulder in the anchor fluke hole can block the reducing shoulder on the anchor fluke, anchor fluke can only move within the specific limits, can outwards not come off, and uses reliable, can prevent the anchor fluke card tubing string that comes off, avoid oil well generation engineering accident.
Description of drawings
Fig. 1 is assembling drawing of the present utility model.
Fig. 2 is the profile after part 1 is cut open from A-A among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
As seen from the figure, embodiment of the present utility model comprises anchor body 1, sealing ring 2, anchor fluke 3, spring 4, outer anchor fluke hole 5 is arranged on the anchor body 1, interior anchor fluke hole 6, the diameter in outer anchor fluke hole 5 is less than the diameter in interior anchor fluke hole 6, form the reducing shoulder between outer anchor fluke hole 5 and the interior anchor fluke hole 6, the reducing shoulder is arranged on the anchor fluke 3, anchor fluke 3 outer end diameters are less than the inner end diameter, pack in the anchor body 15 li in outer anchor fluke hole of anchor fluke 3, anchor fluke 3 has with outer anchor fluke hole 5 and cooperates, sealing ring 2 is installed between anchor fluke 3 and the outer anchor fluke hole 5, spring 4 is sleeved on the anchor fluke 3, and spring 4 is in 6 li in interior anchor fluke hole, and the internal diameter of spring 4 is less than the inner end diameter of anchor fluke 3, spring 4 inner end seats are on the reducing shoulder on the anchor fluke 3, and spring 4 outer face seats are outside on the reducing shoulder between anchor fluke hole 5 and the interior anchor fluke hole 6.
Anchor fluke 3 external surfaces have teeth, can project to the external surface of anchor body 1, and are also identical with existing hydraulic anchor.
On oil well pump, when the pump upward pressure raise, pressure was released anchor fluke 3, is anchored on the oil well casing, oil pipe is maintained static, the adverse consequences of avoiding oil pipe extension to cause under the utility model.When not needing grappling, the oil well pressure balance, anchor fluke 3 is regained under the effect of spring 4, and tubing string loses grappling, tubing string can be proposed smoothly.
The utility model also can be connected on the packer, under pressure, packer work, simultaneously grappling of hydraulic anchor maintains static packer, finishes the operation of oil well different process.
The utility model inwardly comes off for fear of anchor fluke 3, also will interstage sleeve be set at anchor body 1, prevents that anchor fluke 3 from inwardly coming off.
