Description
Technical field
This utility model relates to a kind of detecting instrument, particularly relates to a kind of packet seal inspection tester.
Background technology
Packer refers to have elastic sealing elements, and whereby packing various sizes tubing string and well between and
Annular space between tubing string, and completely cut off payzone, to control to produce (note) liquid, the downhole tool of protection sleeve pipe.
Decrease Wel packing plug water construction operation, no killing well operation without open flow can be conveniently realized, and can be double
To bearing high pressure, service life is long, and the cup packer that oil field is commonly used is self-sealing.Its leather cup external diameter is more than
Casing inner diameter, realizes the sealing of packer by the interference fit of leather cup Yu sleeve pipe, and when going into the well, resistance is big, skin
Bowl is easy to wear and scratches, thus loses sealing.The envelope tester sealing to packer is tested so needing to use
Performance detects.Traditional test envelope tester be all directly by compare the pressure at the upper and lower two ends of sealing ring with
Reach the purpose that inspection seals, but if there is the situation of seal failure, it is impossible to judgement is that packer occurs
There is breakage in the damaged sealing ring still testing envelope tester.
Utility model content
The purpose of this utility model is that provides a kind of packet seal inspection tester to solve the problems referred to above.
This utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of packet seal inspection tester, including main body, upward pressure sensor, lower pressure sensor, upper close
Seal ring, lower sealing ring, middle pressure transducer, flow transducer and circuit control panel, described upward pressure senses
Device and described lower pressure sensor are respectively fixedly disposed at the top and bottom of described main body, described upper sealing ring
All be set with setting on the body with described lower sealing ring, and described upper sealing ring and described lower sealing ring it
Between be provided with gap, medium pressure force transducer and described flow transducer and be respectively positioned on described upper sealing ring and institute
State in the gap between lower sealing ring, described main body be internally provided with cavity, described circuit control panel is arranged
In described cavity, and its signal end by holding wire respectively with described upward pressure sensor, described downforce
Sensor, medium pressure force transducer and described flow transducer connect.
Specifically, described main body includes that upper shell and lower house, described lower house and described upper shell pass through spiral shell
Stricture of vagina is tightly connected, and the joint face of described upper shell and described lower house is arranged on described upper sealing ring with described
At the contact surface of main body.
Specifically, the upper end of described main body, lower end and sidewall are provided with signal string holes, described signal string holes
It is tightly connected with described holding wire, and described upward pressure sensor, described lower pressure sensor, medium pressure
Force transducer and described flow transducer are separately positioned at corresponding signal string holes, and by described signal
The orifice sealing of string holes.
Specifically, described circuit control panel includes processing chip, battery and wireless signal transmitter.
The beneficial effects of the utility model are:
This utility model one packet seal inspection tester, by arranging two sealing rings, can make wherein one
In the case of individual sealing ring breaks down, another sealing ring remains able to normally work；Simultaneously by two
Pressure transducer and the breakage of flow transducer detection sealing ring in adding in individual sealing ring, it is to avoid because
The breakage of sealing ring and erroneous judgement are packer lost efficacy.
Accompanying drawing explanation
Fig. 1 is the sectional view of a kind of packet seal inspection tester described in the utility model.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
As it is shown in figure 1, this utility model one packet seal inspection tester, including main body 1, upward pressure sensing
Device 2, lower pressure sensor 3, upper sealing ring 8, lower sealing ring 9, middle pressure transducer 6, flow transducer
7 and circuit control panel 4, upward pressure sensor 2 and lower pressure sensor 3 be respectively fixedly disposed at main body 1
Top and bottom, upper sealing ring 8 and lower sealing ring 9 are all set with setting on the body 1, and upper sealing ring 8
And between lower sealing ring 9, it being provided with gap, middle pressure transducer 6 and flow transducer 7 are respectively positioned on sealing
In gap between ring 8 and lower sealing ring 9, main body 1 be internally provided with cavity 13, circuit control panel 4
It is arranged in cavity 13, and its signal end is passed with upward pressure sensor 2, downforce respectively by holding wire 5
Sensor 3, middle pressure transducer 6 and flow transducer 7 connect, and main body 1 includes upper shell 12 and lower house
11, lower house 11 and upper shell 12 are connected by thread seal, and upper shell 12 and the company of lower house 11
Junction is arranged at the contact surface of upper sealing ring 8 and main body 1, and the upper end of main body 1, lower end and sidewall are all provided with
Being equipped with signal string holes, signal string holes is tightly connected with holding wire 5, and upward pressure sensor 2, downforce sensing
Device 3, middle pressure transducer 6 and flow transducer 7 are separately positioned at corresponding signal string holes, and will
The orifice sealing of signal string holes, circuit control panel 4 includes processing chip, battery and wireless signal transmitter.
The operation principle of a kind of packet seal inspection tester of this utility model is as follows:
This utility model is placed to detecting position, and makes sealing ring be connected with the inner wall sealing at detection position,
Now, should be at the state being hedged off from the outer world between upper sealing ring and lower seal.
Upward pressure sensor 2 detection and the pressure condition of upper oil reservoir, the lower oil reservoir of lower pressure sensor 3 detection
Pressure state, when detecting, the upwards top adding liquid of sealing ring so that it is pressure increases, if
The force value that lower pressure sensor 3 detects does not changes, then prove that packer sealing is complete；If downforce
The change of the force value that the force value that sensor 3 detects detects with upward pressure sensor 2 and change, then
Prove that packer breaks down or the sealing ring of tester breaks down；Now centering pressure transducer 6 He
Flow transducer 7 is checked, if the force value that middle pressure transducer 6 detects is with upward pressure sensor 2
Force value change, or flow transducer 7 detected liquid between upper sealing ring and lower seal flow
Cross, then prove that tester breaks down, it is therefore desirable to change tester and carry out secondary detection.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, every new according to this practicality
The technology deformation that the technical scheme of type is made, within each falling within protection domain of the present utility model.
