Abstract
The utility model relates to a packer for oil field. It discloses a technology of fully-closed hydraulic packer, which adopts a structure of fully enclosed hydraulic pressure and solves the failure of setting sand de-archive caused by the dirty liquid and deposition in the well. The outside of the lower end of the upper connection 1 connects the connecting sleeve 6 hermetically. The inner side articulates the inner fluid sealant cylinder 2. A set one-way valve 4 and a de-archive one-way valve 5 are disposed on the connecting sleeve 6. A lower connecter 9 is sealing connected with the lower end, and an outer close-up glue tube 8 is attached outside the lower end. The upper sealing ring cavity 3 which is composed of the upper connection 1 and the inner sealing tubing, and the lower sealing ring cavity 7 which is composed of he lower connecter 9 and the outer sealing tubing 8 are communicated with the set one-way valve one-way valve 4 and the de-archive 5. Self-locking is realized after setting and the well backwashing is realized when desterilizing. It can be used repeatedly. The setting pressure is 3MPa, the operating differential pressure <=25MPa, and the de-archive pressure <=6 MPa. It is adapted for the ponding production practice of the oil field and the oil well and the separate zone water flooding operation of the water injection well.
Description
Affiliated technical field the utility model belongs to petroleum machinery, the totally-enclosed hydraulic packer of particularly a kind of water blockoff, water injection technology.
Background technology is present, and the employed hydraulic packer in oily vapour field uses in the serious well of some sand output wells and fouling and polluted often, and serious meeting causes and sets, the deblocking failure, the more serious overhaul accident that causes.
The summary of the invention the purpose of this utility model is to overcome above technical deficiency, provides a kind of and sets, deblocking finished by tool interior pressure liquid, and is not contaminated, the totally-enclosed hydraulic packer of reliable operation.
Task of the present utility model is, totally-enclosed hydraulic packer has the top connection lower end outside adapter sleeve that is tightly connected, the inboard articulates interior cartridge, install on the adapter sleeve and set one way valve and deblocking one way valve, the be tightly connected lower contact outside, lower end articulates the external seal packing element, the lower seal ring cavity that the upper sealing ring chamber that is made of top connection, interior cartridge and lower contact, external seal packing element constitute with set one way valve 4 and deblocking one way valve 5 communicates, constitute hydraulic channel.
The utlity model has following characteristics: one, totally-enclosed hydraulic packer sets, deblocking is finished by internal pressure liquid, and is not contaminated, sets, deblocking is reliable; Its two, totally-enclosed hydraulic packer inside sets one way valve and deblocking one way valve, sets the back and stops pressing not deblocking of packer in the oil pipe.
Description of drawings specifies with embodiment below in conjunction with accompanying drawing.
Fig. 1 shows totally-enclosed hydraulic packer structure chart.
Among Fig. 1, the 1-top connection; Cartridge in the 2-; 3-upper sealing ring chamber; 4-sets one way valve; 5-deblocking one way valve; The 6-adapter sleeve; 7-lower seal ring cavity; 8-external seal packing element; The 9-lower contact
The specific embodiment is with reference to accompanying drawing 1, cartridge 2 formed dress pressure liquid in the upper sealing ring chamber 3 in top connection 1 inside of totally-enclosed hydraulic packer articulated, install in the adapter sleeve 6 and set one way valve 5 and deblocking one way valve 6, lower contact 9 outsides constitute lower seal ring cavity 7 in the middle of articulating external seal packing element 8, top connection 1, adapter sleeve 6, lower contact 9 are tightly connected, upper sealing ring chamber 3 by set one way valve 4, deblocking one way valve 5 is communicated with lower seal ring cavity 7; Cartridge 2 was delivered to upper sealing ring chamber 3 internal pressure liquid in high pressure liquid stream acted on when setting, and opened and set one way valve 4, entered lower seal ring cavity 7 and acted on external seal packing element 8, set to set one way valve 4 when finishing and close; High pressure liquid stream acts on external seal packing element 8 and is delivered to the pressure liquid that enters when setting in the lower seal ring cavity 7 during deblocking, opens deblocking one way valve 5, flows back to upper sealing ring chamber 3, the packer deblocking.
The technical performance parameter
Set pressure 3MPa;
Operting differential pressure≤25MPa;
Separate seal pressure≤6MPa.
Totally-enclosed hydraulic packer is applicable to oilfield water blockoff oil producing operation and water injection well seperated layer water injection operation.
