Abstract
The utility model provides a pipe column plugging device which comprises a columnar sliding block salvage anchor body, a clamping sleeve, a leather cup and a conical body, wherein the clamping sleeve is arranged at the upper end of the sliding block salvage anchor body, sleeved outside the sliding block salvage anchor body and tightly attached to the outer wall of the sliding block salvage anchor body, the leather cup is connected with the clamping sleeve and also sleeved outside the sliding block salvage anchor body, and the conical body is arranged on the outer wall of the sliding block salvage anchor body and provided with a conical surface. Therefore, once a pipe column meets resistance, a striking stick is thrown into the pipe column from the ground, plugging of the pipe column can be achieved, a seating joint is not required, and the technical problems of piping and pipe injection of the pipe column can be well solved.
Description
Technical field
The utility model relates to oil field or oil-water well tubing string internal control instrument, relates in particular to a kind of tubing string blanking plug.
Background technology
Prevent that the fluid the most basic excessive measure in the tubing string from being kill-job, this method is fit to the blowout prevention of all wells.For straight well, the technician has designed various tubing string blanking plugs, and the tubing string blanking plug generally all needs the special-purpose joint that is located in, and is not located in joint in case this well casing post designs, and blanking plug just can't be realized normal location and sealing.And the oil field, land in many cases, and tubing string is not located in joint with special-purpose blowout prevention.
The utility model content
The utility model purpose is to provide a kind of tubing string blanking plug, and being used for solving existing tubing string blanking plug does not have the problem that joint then can't be realized normal location and sealing that is located in.
For solving the problems of the technologies described above, the utility model provides a kind of tubing string blanking plug, and described tubing string blanking plug comprises:
The slide block of column is salvaged the anchor body;
Cutting ferrule is arranged at the upper end that described slide block is salvaged the anchor body, and is sheathed on the outside that described slide block is salvaged the anchor body, and described cutting ferrule is close on the outer wall of described slide block salvaging anchor body;
With the leather cup that described cutting ferrule is connected, described leather cup also is sheathed on the outside that described slide block is salvaged the anchor body; And
Being arranged at described slide block salvages on the outer wall of anchor body, has a cone of taper surface.
Preferably, described tubing string blanking plug comprises that also being arranged at described slide block salvages jump ring between anchor body and the described cutting ferrule, and the inner surface of described cutting ferrule is provided with a plurality of latches that can be connected with a joggle with described jump ring.
Preferably, described leather cup is connected with engaging or bonding way with the edge of described cutting ferrule below.
Preferably, described slide block is salvaged near the outer wall of anchor body described leather cup and is provided with the holding part that depression is used for ccontaining described leather cup.
Preferably, described tubing string blanking plug also comprises the anchor block that is arranged at described slide block salvaging anchor body below.
The utlity model has following beneficial effect: just can realize that tubing string stops up as long as be hampered, can well solve the technical barrier of tubing string piping, pipe spray.
Description of drawings
Fig. 1 is the schematic cross-section of tubing string blanking plug of the present utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Please refer to Fig. 1, the utility model embodiment provides a kind of tubing string blanking plug 100, comprises slide block salvaging anchor body 10, cutting ferrule 20, jump ring 30, leather cup 40, cone 12 and anchor block 14.
It is column that slide block is salvaged anchor body 10, and its lower end is sharp-pointed coniform.
The lateral wall that slide block is salvaged anchor body 10 is provided with groove, jump ring 30 is fixed in the described groove, and the inner surface of described cutting ferrule is provided with a plurality of latches 22, when tubing string blanking plug 100 is arranged in the tubing string, described jump ring 30 is connected with a joggle with a described latch 22 wherein, relatively moves preventing.
The edge of leather cup 40 and cutting ferrule 20 belows is connected with engaging, mode such as bonding.
Slide block is salvaged the holding part 24 that near the outer wall of anchor body 10 described leather cup 40 is provided with depression, with ccontaining described leather cup 40.
Below holding part 24, the free-ended position near described leather cup 40 is provided with the cone 12 with taper surface.
The outer wall of the below of slide block salvaging anchor body 10 is provided with the anchor block installation portion 26 of at least one depression, and anchor block 14 is arranged in the described anchor block installation portion 26.
The course of work to the utility model tubing string blanking plug 100 describes below.
The utility model tubing string blanking plug 100 is used in straight well or hole deviation less than 15 ° well.
Tubing string blanking plug 100 is dropped into from the well head tubing string, and after tubing string blanking plug 100 fell to putting in place, the bottom of tubing string blanking plug 100 was subjected to resistance and stops.At this moment, drop into a trip rod in the well head tubing string, under the impact force action of trip rod, it is descending that cutting ferrule 20 drives leather cup 40, and leather cup 40 outwards opens under the effect of the taper surface of cone 12, thereby seals up tubing string; Cutting ferrule 20 meshes with jump ring 30 simultaneously, keeps the wedging state of leather cup 40 and anchor block 14.
Go up the top after leather cup 40 is subjected to the bigger pressure in bottom again, this moment, anchor block 14 was worked under the gravity effect, with tubing string blanking plug 100 anchors in the inside of tubing string.
Tubing string blanking plug 100 of the present utility model is salvaged on anchor body 10 outer walls by cutting ferrule 20, leather cup 40 being set in successively slide block, the middle part design of salvaging anchor body 10 at slide block has cone 12, the bottom design of salvaging anchor body 10 at slide block has anchor block 14, under the effect of impact of trip rod, it is descending that cutting ferrule 20 drives leather cup 40, leather cup 40 outwards opens under the effect of the taper surface of cone 12, thereby seals up tubing string.Just can realize that as long as be hampered tubing string stops up, need not the special-purpose joint that is located, can well solve the technical barrier of tubing string piping, pipe spray.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
