Abstract
The utility model relates to a packer for downhole operation, particularly a packer with a by-pass device. A by-pass mechanism is arranged on a hydraulic anchor packer. The by-pass mechanism comprises an upper joint, a by-pass mandrel, a gland bush and a by-pass outer cylinder, wherein one end of the by-pass outer cylinder is connected with the hydraulic anchor packer, and the other end is connected with the gland bush; one end of the by-pass mandrel is connected with the upper joint, and the other end with a spline is inserted into the by-pass outer cylinder through the gland bush; the inner wall of the by-pass outer cylinder is provided with a wide key groove, a first narrow key groove and a second narrow key groove; the by-pass mandrel can glide and rotate up and down in the by-pass outer cylinder; the by-pass mechanism is arranged on the hydraulic anchor packer which dismantles a hydraulic anchor; a non extrusion ring is additionally arranged between the gland bush and the spline on the by-pass mandrel. The utility model has the advantages of big diameter, wide purpose, long service life, reliable seat seal, simple packer unsealing operation and rapid packer unsealing operation; huge amounts of liquid can be pumped; various function operations can be completed in one-time downhole operation through an oil pipe perforating gun or other instruments.
Description
Technical field
The utility model relates to the packer of underground work, particularly a kind of bypass type packer that carries.
Background technology
Existing hydraulic anchor packer usually with the supporting use of circulating valve, when operating at the scene, existing hydraulic anchor packer need could normally carry out underground work with the supporting use of circulating valve, and the circulating valve of connection is very difficult when operating at the scene.In addition, because of the hydraulic anchor packer need with the supporting use of circulating valve, also increased very big cost.
The utility model content
In order to solve the weak point of the inconvenient execute-in-place of existing hydraulic anchor packer, it is a kind of on the basis that does not change existing hydraulic anchor packer construction that the purpose of this utility model is to provide, and increased the bypass type that the carries packer of bypass mechanism in the top.
The purpose of this utility model is achieved through the following technical solutions:
The utility model is provided with bypass mechanism on the hydraulic anchor packer, bypass mechanism comprises top connection, bypass axle, gland and bypass urceolus, one end of bypass urceolus is connected on the hydraulic anchor packer, the other end is connected with gland, one end of bypass axle is connected with top connection, the end that other has spline inserts in the bypass urceolus by gland, has wide keyway, the first narrow keyway and the second narrow keyway on the inwall of bypass urceolus; The bypass axle can slide up and down in the bypass urceolus and rotate.
Wherein: described bypass mechanism is located on the hydraulic anchor packer of the hydraulic anchor of dismantling; Between the spline on gland and the bypass axle, be equipped with non-extrusion ring; Between top connection and the bypass axle, be equipped with O-ring seals between gland and the bypass axle and between bypass axle and the bypass urceolus; Between top connection and bypass axle, be provided with two O-ring seals, be provided with an O-ring seals between gland and the bypass axle, be provided with three O-ring seals between bypass axle and the bypass urceolus; After the bypass mechanism on top propped up, the bottom was original hydraulic anchor packer.
Advantage of the present utility model and good effect are:
The utility model is a kind ofly to carry that bypass, latus rectum are big, multipurpose, long-life, set reliable packer, and it is used for formation testing, acidifying, pressure break, water filling, operations such as cementing plug.The design that carries bypass can make the packer unsealing operation simple, fast, the design of big latus rectum can make this packer and all-pass footpath instrument be used, but pump is crossed a large amount of fluids, and can finish various functional operation in once going into the well by oil pipe perforating gun and other instruments.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As Fig. 1, Fig. 3～shown in Figure 5, the utility model is provided with bypass mechanism in the top on the basis that does not change original hydraulic anchor packer 7 structures, and bypass mechanism comprises top connection 1, bypass axle 2, gland 3 and bypass urceolus 5.One end of bypass urceolus 5 is by being threaded on the hydraulic anchor packer 7, the other end is connected with gland 3 by external screw thread, one end of bypass axle 2 is connected with the internal thread of top connection 1 lower end, the end that other has spline 9 inserts in the bypass urceolus 5 by gland 3, and the upper end of top connection 1 is connected with tubing string.Have wide keyway 10, the first narrow keyway 11 and the second narrow keyway 12 on the inwall of bypass urceolus 5, bypass axle 2 can slide up and down in bypass urceolus 5 and rotate.Between the spline 9 on gland 3 and the bypass axle 2, be equipped with non-extrusion ring 4.Between top connection 1 and bypass axle 2, be provided with two O-ring seals 6, be provided with an O-ring seals 6 between gland 3 and the bypass axle 2, be provided with three O-ring seals 6 between bypass axle 2 and the bypass urceolus 5, form slipper seal with hole in the bypass urceolus 5.
When going into the well, transposition spline 9 with bypass axle 2 is placed in the second narrow keyway 12 of bypass urceolus 5 earlier, after packer arrives the setting position, the upper lifting pipe post, transposition spline 9 on the bypass axle 2 is slided in the top wide keyway 10, and dextrorotation tubing string 1/4 (down-hole 3～4) circle is transferred tubing string again, the transposition spline 9 of bypass axle 2 is slided in the first following narrow keyway 11 by wide keyway 10, the bypass axle 2 descending bypass of closing.Lean against the upper surface of gland 3 when the lower surface of top connection 1 after, continue to transfer tubing string, make packer setting.When the needs deblocking, the upper lifting pipe post, bypass axle 2 is up, and bypass is opened, and continues the upper lifting pipe post, the packer deblocking.
As shown in Figure 2, the present embodiment difference from Example 1 is: after the hydraulic anchor on the hydraulic anchor packer 78 is dismantled, be provided with bypass mechanism in the upper end of hydraulic anchor packer 7.Down-hole operation is identical with embodiment 1.
The utility model has guaranteed to be hampered in the process of going into the well and has not set and replace smooth and easy.
