Description
Technical field：
It the utility model is related to test envelope instrument, especially leak detection used in separated-zone water infection oil field neck packer and test encapsulation
Put.
Background technology：
In field of oil field oil extraction, in order to improve recovery ratio, it is necessary to strata division water filling.Separated-zone water infection oil field is exploited just
It is to be layered by packer, whether packer sealing quality represents layering effective, examine its sealing to fail most important.Test
Seal apparatus is the whether intact device of the most frequently used test interlayer packer sealing.And existing packer detecting device is deposited due to reasons in structure
The problem of envelope accuracy rate is low is being tested, thus is influenceing water-injection efficiency, is finally reducing recovery ratio.
Utility model content：
In order to solve the problems, such as that it is low that existing packer detecting device tests envelope accuracy rate.The utility model offer is a kind of to test the stifled of seepage
Plug pressure gauge.The leak detection packer detecting device not only tests envelope accuracy rate height, and can test pressure, lower pressure and temperature
Degree, moreover it is possible to detect and whether the vibratory output of register instrument, i.e. reaction seal section outer wall have the vibration that flow of fluid is formed, so as to sentence
Whether disconnected seal section also has seepage after setting.
The technical solution of the utility model is：The leak detection packer detecting device include connection plug, sleeve pipe, battery sleeve, on
Pressure sensor, lower pressure sensor and vibrating sensor, it is characterised in that：It is connected with sleeve pipe and is connected with connection plug
Battery sleeve, connect and pressure sensor is laterally equipped with the upper part of the plug, have through hole on upper pressure sensor upper end connection plug, even
Connect and lower pressure sensor is longitudinally equipped with plug bottom, sleeve pipe closed chamber is built-in with vibrating sensor and circuit board, on circuit board
There is temperature measurement circuit, there is communications connector in sleeve pipe, battery sleeve is built-in with the battery being connected with circuit board, connects plug and its lower end
It is equipped with sealing ring outside.
The utility model has the advantages that：The leak detection packer detecting device is connected with due to using to connect under plug
Battery sleeve is connected with sleeve pipe, connects and pressure sensor is laterally equipped with the upper part of the plug, upper pressure sensor upper end connection is stifled
There is through hole on head, connection plug is longitudinally equipped with lower pressure sensor in bottom, and sleeve pipe closed chamber is built-in with vibrating sensor and electricity
Road plate, there is temperature measurement circuit on circuit board, there is communications connector in sleeve pipe, battery sleeve is built-in with the battery being connected with circuit board, connection
The structure of sealing ring is equipped with outside plug and its lower end.Utilize thermometric electricity on upper pressure sensor, lower pressure sensor, circuit board
Road and vibrating sensor, in addition to the normally signal such as detection pressure and temp, additionally it is possible to detecting instrument vibratory output, believe in company with pressure
Number together record storage, after fetching ground playback curve, from oscillating curve can accurate judgement seal section set it is whether intact.Up and down
The situation of pressure separation can determine that packer is intact, the unseparated situation of two-way pressure, if vibration, illustrate to set not sternly,
Need to retest, illustrate that packer does not seal necessarily if without friction.Thus the leak detection packer detecting device not only tests envelope
Accuracy rate is high, and can test pressure, lower pressure and temperature, moreover it is possible to detects the vibratory output of simultaneously register instrument, that is, reacts close
Whether envelope section outer wall has the vibration that flow of fluid is formed, so as to judge whether seal section also has seepage after setting.
Brief description of the drawings：
Accompanying drawing 1 is agent structure schematic diagram on the utility model.
1- connections plug in accompanying drawing, 2- sleeve pipes, 3- battery sleeves, the upper pressure sensors of 4-, 5- lower pressure sensors, 6- vibrations
Sensor.
Embodiment：
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in drawings, the leak detection packer detecting device includes connection plug 1, sleeve pipe 2, battery sleeve 3, upper pressure sensor
4th, lower pressure sensor 5 and vibrating sensor 6.Sleeve pipe 2 is connected with connection plug 1, battery sleeve 3 is connected with sleeve pipe 2, even
Connect and pressure sensor 4 is laterally equipped with the top of plug 1, have through hole on the upper upper end of pressure sensor 4 connection plug 1, connection is blocked up
Longitudinally it is equipped with lower pressure sensor 5 in first 1 bottom, the closed chamber of sleeve pipe 2 is built-in with vibrating sensor 6 and circuit board, on circuit board
There is temperature measurement circuit, circuit board is responsible for collection and record data, the method for wastage is judged using test vibration amount, and missed with this
Amount, which can further be drawn, tests sealed knot opinion, avoids retest, and ensures to test the credibility of envelope data.There is communication in sleeve pipe 2
Socket, battery sleeve 3 are built-in with the battery being connected with circuit board, connect and are equipped with sealing ring outside plug 1 and the lower end of sleeve pipe 2.The seepage
Packer detecting device is detected while pressure, lower pressure and temperature in test and record, tests and register instrument external seal section is set
Leak magnitude afterwards.Solve original method of testing, can not judge that packer does not seal or seal section sets the problem of not tight,
Solve original method of testing, packer sealing can only be judged, the problem of packer does not seal can not be judged.
The course of work：
When testing envelope test, by the packer detecting device twist-on to testing seal section, well is put into steel wire rope connection seal section
Under, set by gravity on eccentric injection mandrel, set the leather cup distending on rear seal section, should by the fluid isolation up and down of oil pipe
Two-way pressure sensor on packer detecting device detects and records on oil pipe pressure under pressure and oil pipe respectively.
The leak detection packer detecting device has：
When the 1st, testing envelope test, there is the unseparated situation of two-way pressure, can not judge it is what reason in the past, and use seepage
When detection packer detecting device carries out testing envelope, the credibility of data can be assert, can confirm to judge whether that needs retest, avoid completely
Mistake tests sealed knot opinion；
When the 2nd, carrying out testing envelope using monitoring of leakage packer detecting device, as two-way pressure does not separate and without friction, can definitely it judge
Packer does not seal, and this is the conclusion that conventional packer detecting device can not be drawn.
3rd, the size of packer detecting device of leak detection packer detecting device and routine, connector are identical, and can directly replace makes
With.
