Abstract
The utility model relates to a water-filling packer squirm eliminating device which is used for eliminating the squirm of a packer with water-filling pressure in oil extraction, and is composed of an upper contact 1, a cylinder sleeve 4, a boss 6, a center pipe 9, etc. The center pipe 9 is connected with the upper contact 1, and the cylinder sleeve 4 is sheathed on the center pipe 9 and is connected with the thread of the lower end of the upper contact 1. Fan-shaped convex blocks are distributed evenly on the lower end face of the boss 6. Grooves corresponding to the convex blocks are distributed evenly on the inner table face of the cylinder sleeve 4, and a tooth-embedding clutch device is composed of the convex blocks and the grooves. The utility model has the advantages of simple structure, convenient assemblage, convenient maintenance, convenient construction, reliable work, non-injury for a sleeve pipe, etc.
Description
The utility model relates to eliminates the water injection packer wriggling arrester that causes the packer wriggling because of water injection pressure in a kind of oil exploitation.
At present, in the separated-zone water infection oil field development process, be used to solve and mainly contain following several: 1. adopt bi-directional slip formula packer and sleeve pipe to carry out grappling because of water injection pressure causes the method for packer wriggling, its major defect is: grappling belongs to dead grappling, be difficult to remove, anchor fluke has destruction to sleeve pipe; 2. layered water injection pipe is pillared to the shaft bottom, its shortcoming is: only effective to the low pressure water injection shallow well, and destroy artificial bottom of a well, tubing string easily and easily produce helical buckling, increased the difficulty of pulling, test; 3. adopt hydraulic anchor to carry out grappling, its shortcoming is: anchor fluke has very big destruction to sleeve pipe, and to shaking out, the well that fouling is serious, anchor fluke are easily stuck, cause the overhaul accident.
The purpose of this utility model is: provide a kind of simple in structure and can effectively eliminate because of " pressure effect " makes packer and produce the water injection packer wriggling arrester of wriggling.
The utility model is achieved in that water injection packer wriggling arrester is made up of top connection 1, seal groove 2, spiracle 3, cylinder sleeve 4, respiratory cavity 5, boss 6, pressure guide hole 7, pressure chamber 8, central tube 9, lower contact 10, central tube 9 upper ends are plugged in the top connection 1, cylinder sleeve 4 is enclosed within on the central tube 9 and with top connection 1 lower end and is threaded, and central tube 9 lower ends are threaded with lower contact 10; Be provided with a stepped boss 6 at the middle part of central tube 9, the annular cross-sectional area of boss 6 equates with the cross-sectional area of pipe aperture, boss 6 contacts with cylinder sleeve 4 inwalls, and cylinder sleeve 4 surrounded respiratory cavity 5 and pressure chamber 8, have spiracle 3 on the cylinder sleeve 4, it communicates with respiratory cavity 5, have pressure guide hole 7 on the boss 6, it communicates with pressure chamber 8, the interior table top of boss 6 lower surfaces and cylinder sleeve 4 overlaps mutually. and on the outer wall of the inwall of top connection 1, cylinder sleeve 4 and central tube 9, have seal groove 2, " O " shape black box is housed in seal groove 2.
Boss 6 lower surfaces are evenly equipped with the fan-shaped projection, are evenly equipped with on the interior table top of cylinder sleeve 4 and the corresponding groove of projection. and projection and groove constitute jaw clutch device.
Advantage of the present utility model is: eliminate the packer wriggling that is produced by pressure effect with the cavity that central tube and cylinder sleeve form, utilize simultaneously the projection of boss and the jaw clutch device of groove formation to come transfer torque again, therefore have simple in structure, assembling is easy to maintenance. be convenient to construction, reliable operation is to characteristics such as sleeve pipe not damageds.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1: water injection packer wriggling arrester structural representation;
Fig. 2: A-A sectional drawing
The utility model is made up of top connection 1, seal groove 2, spiracle 3, cylinder sleeve 4, respiratory cavity 5, boss 6, pressure guide hole 7, pressure chamber 8, central tube 9, lower contact 10, central tube 9 upper ends are plugged in the top connection 1, cylinder sleeve 4 is enclosed within on the central tube 9 and with top connection 1 lower end and is threaded, and central tube 9 lower ends are threaded with lower contact 10; Be provided with a stepped boss 6 at the middle part of central tube 9, the annular cross-sectional area of boss 6 equates with the cross-sectional area of pipe aperture, boss 6 contacts with cylinder sleeve 4 inwalls, and cylinder sleeve 4 surrounded respiratory cavity 5 and pressure chamber 8, have spiracle 3 on the cylinder sleeve 4, it communicates with respiratory cavity 5, have pressure guide hole 7 on the boss 6, it communicates with pressure chamber 8, the interior table top of boss 6 lower surfaces and cylinder sleeve 4 overlaps mutually, on the outer wall of the inwall of top connection 1, cylinder sleeve 4 and central tube 9, have seal groove 2, " O " shape black box is housed in seal groove 2.
Boss 6 lower surfaces are evenly equipped with the fan-shaped projection, on the interior table top of cylinder sleeve 4, be evenly equipped with and the corresponding groove of projection, projection and groove constitute jaw clutch device, its effect is when the chance of the tubing string below packer card needs the back-off lift pipe string, the mutual interlock transfer torque of tooth embedding, guarantee trips out the tubing string back-off of bottom, has seal groove 2 on the outer wall of the inwall of top connection 1, cylinder sleeve 4 and central tube 9, and " O " shape seal group body is housed in the seal groove 2.
When job execution, the utility model is serially connected with above the first order packer, together go into well together with other dispensing instrument, at this moment tooth embedding is mutual interlock, but transfer torque, after packer set, because the effect of water injection pressure, pressure enters pressure chamber 8 by pressure guide hole 7, at this moment be subjected to two power in the pressure chamber 8, a power makes progress, and it acts on boss 6 lower surfaces of central tube 9, because the sectional area of boss 6 equates with the sectional area of pipe aperture cross section, thereby act on pressure and the pressure equal and opposite in direction that uses on boss 6 lower surfaces on the bottom valve, and the direction of these two power is opposite, thereby cancels out each other, and another power is downward, act on the interior table top of cylinder sleeve 4, the tubing string vertical pulling that pressure makes cylinder sleeve 4 connect together with top connection 1, owing to have spiracle 3 on the cylinder sleeve 4, spiracle 3 communicates with respiratory cavity 5, guaranteed moving down of cylinder sleeve 4, so just make the following tubing string of arrester keep motionless, and make its stroke occur in arrester originally on one's body, eliminated the wriggling of packer.
