Description
Technical field
The utility model is the corollary apparatus of separated-zone water infection oil field well, is the setting corollary apparatus of a kind of water injection string pressure testing.
Background technology
In order to allow water injection well play larger effect, oil field is taked to penetrate out multiple layers of position to water injection well and is carried out seperated layer water injection, makes a bite water injection well can to multiple layers of position water filling.Because the water injection pressure of each water filling layer position is different with water injection rate, realize multilayer water filling simultaneously, water injection string under needing enter separator and injection well downhole flow regulator, use these kits, need to suppress tubing string, suppress pressure and be generally 10-25MPa, therefore, separate layer water injection string needs airtight, general separate layer water injection string only needs under the bottom of tubing string, enter ball-and-seat just can realize the airtight of water injection string, ball-and-seat is used for the current liquid upwards flowed from bottom, and for blocking the liquid from top, makes the pressure testing of tubing string energy also can well-flushing.But adopt this tubing string, just can not have water filling layer in the bottom of ball-and-seat, make the scope of application of current water injection string less, in order to ensure that the number of plies that water injection well can have exploitation to need participates in water filling, only many next cover packer and restriction choke (injection well downhole flow regulator) on water injection string, cause water injection string complicated, failpoint is many, the poor reliability of tubing string, test supporting wide in variety, instrument consumption is many, and cost is high, maintenance workload of going into the well is large, judges that the accuracy of Problem of Failure declines.
Summary of the invention
The purpose of this utility model is design a kind of water injection string pressure testing setting corollary apparatus, solves above-mentioned Problems existing, makes its water injection string structure simple, reduces layered water injection tool, improve the reliability of water injection string, makes water injection well can water filling reliably and with long-term.
The purpose of this utility model is achieved in that to comprise suppresses setting Y341 packer, the Y341 packer of institute's art comprises setting mechanism, cartridge, locking mechanism, connector, setting mechanism, cartridge, locking mechanism, connector connects successively, constant pressure turn on device is connected under connector, the opening pressure of constant pressure turn on device is higher than the setting pressure of Y341 packer, setting pressure is squeezed in Y341 packer, setting mechanism promotes the rear Sealed casing pipe of cartridge expansion downwards, the expansion state of locking mechanism locking cartridge, after squeezing into the distress resolves in Y341 packer, cartridge still can be in expansion state, now constant pressure turn on device is not opened.
Y341 packer is suppressed and is settingly completed follow-up pressure of continuing rising, and described constant pressure turn on device is opened and water injection well sleeve pipe UNICOM, and when described constant pressure turn on device internal pressure is higher than Y341 packer set pressure 2-6MPa, constant pressure turn on device is opened and water injection well sleeve pipe UNICOM.
Constant pressure turn on device comprises closedown valve ball, sealing ring, cut off pin, sliding sleeve, housing, sliding sleeve is arranged in housing, cutting off pin laterally interts at housing, on sliding sleeve, making sliding sleeve be cut off pin is fixed on housing, the internal diameter of sliding sleeve is less than the diameter of closing valve ball, after closedown valve ball knocks down sliding sleeve, shut off valve ball seat is on the valve port of sliding sleeve, close the valve port fitted seal of valve ball and sliding sleeve, gap between the inwall of housing and the outer wall of sliding sleeve is sealed by sealing ring, sealing ring is in be cut off on pin, housing has communication groove, communication groove is under sealing ring, the lower port of housing can stop that sliding sleeve deviates from housing.
The beneficial effects of the utility model are: Y341 packer is suppressed and settingly completed follow-up pressure of continuing rising, constant pressure turn on device is opened and water injection well sleeve pipe UNICOM, inject water and can carry out water filling by the passage of UNICOM, make its Y341 packer can following enter between bottom water filling layer, a water filling layer can also be arranged at the bottom of Y341 packer, the kit of separate layer water injection string can be reduced when meeting the water filling number of plies of development requirement, namely packer is reduced, restriction choke, therefore, the utility model can reach goal of the invention, current Problems existing can be overcome, water injection string structure is simple, the failpoint of water injection string is few, the reliability of water injection string can be improved, water injection well can water filling reliably and with long-term, there is significant economic benefit.
Accompanying drawing explanation
Accompanying drawing 1 is the assembling drawing of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, embodiment of the present utility model is described.
As seen from Figure 1, embodiment of the present utility model comprises suppresses setting Y341 packer, constant pressure turn on device, the Y341 packer of institute's art comprises setting mechanism 1, cartridge 2, locking mechanism 3, connector 4, setting mechanism 1, cartridge 2, locking mechanism 3, connector 4 connects successively, constant pressure turn on device is connected under connector 4, the opening pressure of constant pressure turn on device is higher than the setting pressure of Y341 packer, setting pressure is squeezed in Y341 packer, setting mechanism 1 promotes cartridge 2 downwards and expands rear Sealed casing pipe, locking mechanism 3 locks the expansion state of cartridge 2, after squeezing into the distress resolves in Y341 packer, cartridge 2 still can be in expansion state, all the time water injection well sleeve pipe is sealed, now constant pressure turn on device is not opened.Y341 packer is suppressed and is settingly completed follow-up pressure of continuing rising, described constant pressure turn on device just can be opened and water injection well sleeve pipe UNICOM, when described constant pressure turn on device internal pressure is higher than Y341 packer set pressure 2-6MPa, constant pressure turn on device could be opened and water injection well sleeve pipe UNICOM, if open up pressure to be less than, Y341 packer can be caused also there is no setting just unlatching, make down the work failure of water injection string, if it is large to open earthenware pressure, the hypertonia squeezed in water injection string, ground installation and water injection pipe can be damaged, also can cause down the work failure of water injection string.Constant pressure turn on device comprises closes valve ball 5, sealing ring 6, cut off pin 7, sliding sleeve 8, housing 10, sliding sleeve 8 is arranged in housing 10, cutting off pin 7 laterally interts at housing 10, on sliding sleeve 8, sliding sleeve 8 is made to be cut off pin 7 fixing on the housing 10, the internal diameter of sliding sleeve 8 is less than the diameter of closing valve ball 5, after closedown valve ball 5 knocks down sliding sleeve 8, close valve ball 5 on the valve port of sliding sleeve 8, close the valve port fitted seal of valve ball 5 and sliding sleeve 8, gap between the inwall of housing 10 and the outer wall of sliding sleeve 8 is sealed by sealing ring 6, sealing ring 6 is in be cut off on pin 7, housing 10 has communication groove 9, communication groove 9 is under sealing ring 6, the internal diameter of housing 10 lower port is less than the external diameter of sliding sleeve 8, the lower port of housing 10 can stop that sliding sleeve 8 is deviate from housing 10 and fallen in well.
Can calculate on sliding sleeve 8 according to the needs of suppressed power and the external diameter of sliding sleeve 8 and bear downward thrust, then determine according to this thrust material and the diameter of cutting off pin 7.
