Abstract
The invention discloses a filling and permanent fixing type pipe-external sealing and separating method and tool thereof. The method and the tool are suitable for sealing and separating different stratum sections outside a sleeve under an oil wheel. The method comprises the following steps: filling a curing expansive agent (3) between a sealed rubber sleeve (4) inside a filling and permanent fixing type pipe-external packer and a central pipe (2), lowering the filling and permanent fixing type pipe-external packer to a designed position inside the oil well along with a pipe string, and building pressure, enabling water or slurry to enter into a cavity between the sealed rubber sleeve (4) inside the filling and permanent fixing type pipe-external packer and the central pipe (2), and carrying out expansion and solidification after water or slurry is mixed with the curing expansive agent (3) filling between the sealed rubber sleeve (4) inside the filling and permanent fixing type pipe-external packer and the central pipe (2), so as to enable the entire packer to form an entity, and accomplishing oil well sealing and separating construction. The filling and permanent fixing type pipe-external packing tool provided by the invention has a simple structure, integrates the advantages of a filling and permanent pipe-external packer and a compression-type pipe-external packer, and overcomes the defects of the filling and permanent pipe-external packer and the compression-type pipe-external packer, and greatly improves well completion quality and prolongs the service life of oil and gas wells.
Description
Technical field
The present invention relates to a kind of outer packing method of filling permanent type pipe and instrument thereof, be applicable to the oil field well stratomere that packing is different outside sleeve pipe.
Background technology
Under Oil/gas Well conditions of complex geological, in Well Completion Engineering of Oil Reservoirs, the normal external packer of pipe that uses isolates different intervals, as height kill-job section, oil-water well section etc., the outer packing method of pipe of current onsite application mainly contains and adopts fill-type and compression packer to carry out packing two kinds: fill-type packing is the method that fill liquid makes its isolation of expanding in packing element cavity, feature is that expansion ratio is large, the suitable large hole diameter packing of bore hole, shortcoming is that in the aging damaged rear chamber of down-hole mal-condition lower rubber cylinder, liquid drain out loses packing effect; Another kind method adopts compression packer, become realize packing greatly by compression packer packing element diameter, and feature is that entity packing element is not easy to lose efficacy, and seal pressure differential is also relatively large, but compression-expansion is than limited, is difficult to adapt to the large hole diameter of bore hole or irregular borehole.
Summary of the invention
The object of this invention is to provide a kind of outer packing method of filling permanent type pipe and instrument, after having filling, charges do not run off, and expansion ratio is large, and packing is effective, and the life-span is long.
The present invention is achieved in that filling setting expansion agent between cartridge and central tube in filling permanent type external packer of pipe, by filling permanent type external packer of pipe with under tubing string to design attitude in oil well, build the pressure, water or mud is made to enter in the cavity in filling permanent type external packer of pipe between cartridge and central tube by valve hoop, water or mud with in filling permanent type external packer of pipe between cartridge with central tube the setting expansion agent of filling mix after expansion curing, make whole packer form an entity, complete oil well packing construction.The method packing element there will not be leakage failure phenomenon, greatly improves sealing reliability and the application life of oil well packing.
For an instrument for the outer packing method of filling permanent type pipe, it is made up of upper box cupling, central tube, interior cartridge, outer protection packing element, valve hoop, lower contact, and in it, between cartridge and central tube, charges are setting expansion agent.
Structure of the present invention is simple, combines the advantage of fill-type external packer of pipe and compression external packer of pipe, overcomes again their shortcoming, substantially increase total completion time and Oil/gas Well life-span.
Accompanying drawing explanation
Accompanying drawing 1 is structure principle chart of the present invention.
Detailed description of the invention
Describe the present invention below in conjunction with accompanying drawing: filling setting expansion agent (3) between cartridge (4) and central tube (2) in filling permanent type external packer of pipe, by filling permanent type external packer of pipe with under tubing string to design attitude in oil well, build the pressure, water or mud is made to enter in the cavity in filling permanent type external packer of pipe between cartridge (4) and central tube (2) by valve hoop (6), expansion curing after water or mud mix with the setting expansion agent (3) of filling between cartridge (4) with central tube (2) in filling permanent type external packer of pipe, whole packer is made to form an entity, complete oil well packing construction.The method packing element there will not be leakage phenomena, greatly improves sealing reliability and the application life of oil well packing.
A kind of instrument--filling permanent type external packer of pipe for the outer packing method of filling permanent type pipe; it is made up of upper box cupling, central tube, interior cartridge, outer protection packing element, valve hoop, lower contact, and in it, between cartridge and central tube, charges are setting expansion agent.
Claims (2)
1. the outer packing method of filling permanent type pipe, it is characterized in that: filling setting expansion agent (3) between cartridge (4) and central tube (2) in filling permanent type external packer of pipe, by filling permanent type external packer of pipe with under tubing string to design attitude in oil well, build the pressure, water or mud is made to enter in the cavity in filling permanent type external packer of pipe between cartridge (4) and central tube (2) by valve hoop (6), expansion curing after water or mud mix with the setting expansion agent (3) of filling between cartridge (4) with central tube (2) in filling permanent type external packer of pipe, whole packer is made to form an entity, complete oil well packing construction.
2. instrument--the filling permanent type external packer of pipe for the outer packing method of filling permanent type pipe according to claim 1; it is made up of upper box cupling (1), central tube (2), interior cartridge (4), outer protection packing element (5), valve hoop (6), lower contact (7), it is characterized in that: between interior cartridge (4) and central tube (2), be filled with setting expansion agent (3).
