Abstract

A blocking device comprises an upper bond, a mandrel, an upper blocking component, a lower blocking component, a spline outer tube and a tubing and is characterized in that the upper blocking component is provided with a plurality of sections of sealing long tubings, the end faces of the sealing long tubings are the oblique cone angle from 5 degrees to 60 degrees. Two ends of the upper blocking component are provided with a plurality of metal supporting rings. The end faces of the metal supporting rings are the oblique cone angle from 30 degrees to 60 degrees. The lower blocking component are provided with a plurality of sealing tubes, and the end faces of the sealing tubes are the oblique cone angle from 5 degrees to 60 degrees. The inner cores of the sealing tubes are made of non-metal material or flexible graphite. The outer surface of the sealing tube is coated with metal skin. A slips tube is assembled below the mandrel. A slips assembly is arranged outside the slips tube. The utility model has the advantages of good blocking effect, no leakage and enlargement of blocking applicable range. The pressure of blocking is ranged from 10 Mpa to 280 Mpa. The liquid (such as slurry, oil and water) and gas medium with temperature ranged from below -40 DEG C to -650 DEG C can be blocked.

Description

Plugging device
Technical field
The utility model belongs to a kind of formation testing used tool, a kind of plugging device especially for shutoff, packing bore hole, sleeve pipe and aperture, it is applicable to the initial stage exploration in geological test, oil field, drillstem test, well completing test, conventionally test, integration test, the shutoff in informal test and various apertures and packing function.
Background technology
Now, the shutoff of rubber seal cylinder is adopted in the shutoff that is widely used in bore hole, sleeve pipe and the aperture of formation testing, its structure is made up of rubber tube, shutoff chamber and slips etc., because the deficiency on the structure design, set pressure up to more than the 20Mpa, the shutoff success rate is very low, thereby can not be suitable for the above operating mode of shutoff HTHP.Use has limitation.
The utility model content
The purpose of this utility model provides a kind of plugging device, and it is lower to set pressure, and plugging effect is good, does not have and leaks, and is specially adapted to high temperature, the above operating mode of high pressure, and the scope of application is wide.
The purpose of this utility model is achieved by the following technical solution: it comprises top connection, mandrel, on, following blocking component, the spline urceolus, packing element, it is characterized in that: go up blocking component multistage sealing long packing element type is set, the end face of sealing long packing element type is 5 ° of-60 ° of oblique cone angles, the two ends of last blocking component are provided with the multiple tracks metal supporting rings, the end face of multiple tracks metal supporting rings is 30 ° of-60 ° of oblique cone angles, following blocking component is provided with multiple-sealed tube, the end face of sealing drum is 5 ° of-60 ° of oblique cone angles, sealing drum is provided with the inner core of nonmetals or soft graphite, external surface clad metal crust, at the lower set of the mandrel watt tube that is installed, the slips tube outer set watt assembly that is installed.
Between the above-mentioned last blocking component multistage sealing long packing element type support spacer ring is set.
Between the multiple-sealed tube of above-mentioned following blocking component the metal spacer ring is set.
Above-mentioned slips assembly is provided with spring-supported dental lamina.
Connect polylith dental lamina, the carbide alloy block teeth of affixed inclination on the external surface of dental lamina by rotating pin on the above-mentioned slips assembly.
The utility model has the advantages that: plugging effect is good, does not have to leak, and enlarged the scope of application of shutoff, but the pressure of shutoff is 10Mpa-280Mpa, and temperature is-40 ℃-650 ℃ liquid (mud, oil, water etc.) and a gas medium.
