Description
Technical field
The utility model is specifically related to oil well pipe packer load test short circuit.
Background technology
Oil well pipe packer is called for short: packer is one of visual plant in petroleum production engineering, and carrying out two-way voltage-withstand test, load test to packer is all the important indicator evaluating packer quality.
Chinese patent 201120241698 discloses a kind of packer test device, and it is applied to the laboratory test of packer.What it solved is voltage-withstand test technical problem, still can not solve load test Related Technical Issues.
Utility model content
The purpose of this utility model: be the deficiency solving above-mentioned technology, provides a kind of oil well pipe packer load test short, solves load test Related Technical Issues.
The technical scheme realizing the utility model object is: strain tube 3, in hollow tubular, is provided with internal thread 1 at two ends; The stage casing external diameter undergauge of strain tube 3 attenuates, and is fixed with one group of foil gauge 4 in the outside of strain tube 3; Be inserted in protection sleeve 6 in the outside of strain tube 3, between strain tube 3 and protection sleeve, form battery compartment 8, circuit board 5 and battery 9 are installed in battery compartment 8.
Double-layer seal rings 2 and three-layer sealed circle 7 is respectively equipped with between protection sleeve 6 two ends and strain tube 3.
Have an annular table 10 outside strain tube 3 right-hand member, three-layer sealed circle 7, the external diameter of annular table 10 is equal with protection sleeve 6 external diameter, is on same anchor ring.
One group of foil gauge 4 be four and uniform with strain tube 3 in the middle part of on outer wall.
The utility model has following beneficial effect: structure is simple, data measured accurately and reliably.
Accompanying drawing explanation
Fig. 1 is the axial sectional view of the utility model front view.
At Fig. 1: 1. internal thread, 2. double-layer seal rings, 3. strain tube, 4. foil gauge, 5. circuit board, 6. protection sleeve, 7. three-layer sealed circle, 8. battery compartment, 9 batteries, 10. annular table.
Detailed description of the invention
Clearly understand to make the purpose of this utility model, technical scheme and advantage, below in conjunction with drawings and Examples, the utility model is further described, be to be understood that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Exemplary embodiments of the present utility model is as shown in Figure 1: strain tube 3, in hollow tubular, is provided with internal thread 1 at two ends; The stage casing external diameter undergauge of strain tube 3 attenuates, and is fixed with one group of foil gauge 4 in the outside of strain tube 3; Be inserted in protection sleeve 6 in the outside of strain tube 3, between strain tube 3 and protection sleeve, form battery compartment 8, circuit board 5 and battery 9 are installed in battery compartment 8.The structure of strain tube 3 is the spitting image of our common mariages short circuit, but its interlude undergauge attenuates, can for the space of installation foil gauge 4, circuit board 5, battery 9 and battery compartment 8 so that formed with protection sleeve 6.Strain tube 3 two ends external diameter is not isometrical, a wall thickness of left end and right-hand member phase-comparison protection sleeve 6, and after setting up protection sleeve 6, annular table 10 and protection sleeve outer ring surface are on same ring surface.
Double-layer seal rings 2 and three-layer sealed circle 7 is respectively equipped with between protection sleeve 6 two ends and strain tube 3.Double-layer seal rings 2 and three-layer sealed circle 7 are all installed in the outer corresponding cannelure of strain tube 3, for stopping that profit enters battery compartment.
One group of foil gauge 4 is four and is distributed in the middle part of strain tube 3 on outer wall.Foil gauge 4 also can be divided into organizes setting more.Foil gauge 4 is existing products, utilizes that foil gauge 4 is stressed causes resistance value correspondence changing principle afterwards because of deformation, and measure stressed size, electronic scale is also the existing product utilizing this principle to make.
This oil well pipe packer load test short circuit can tension and compression size suffered by detection record downhole packer.The important technological parameters of load test is as follows: the axial load-bearing scope 300kN of load test, measuring accuracy 5%F.S, operating temperature range-20-85 DEG C, work the highest withstand voltage 30MPa, power acquisition lithium iron phosphate charging battery, sample rate 10 points per second, stream time 90 days.
