Abstract
A kind of gravel filling device, comprises drilling rod actuator, sleeve pipe, upper locating ring, block, centralizer, spring and lower locating ring; When carrying out gravel and filling, descending and the contact blocks of drilling rod actuator, the power that drilling rod actuator acts on block passes to centralizer, power transmission is given spring again by centralizer, spring compresses under force and makes centralizer relative to sleeve pipe slide downward, trapezoidal hole on sleeve pipe is opened, gravel liquid flows out trapezoidal hole by the positive filling channel of drilling rod actuator, complete gravel and fill link, when drilling rod actuator is descending by back pressure passage release pressure, the RunddichtringO of O up and down simultaneously on drilling rod actuator prevents internal environment contaminated.During forward gravel end-of-fill, drilling rod actuator is up, and spring is released, and centralizer blocks trapezoidal hole along sleeve pipe is up, completes gravel packing operations.The utility model can utilize the flexible gravel that realizes fast of spring to fill, and can repeatedly fill, thus reduces workload, cost-saving.
Description
Technical field
The utility model relates to oil drilling device field, the gravel filling device specifically in a kind of drilling completion technique.
Background technology
At present, traditional gravel fill tool is made up of leather cup and conversion assembly, and gravel liquid pumps in oil pipe, enters the annular space between screen casing and sleeve pipe through conversion assembly, now leather cup seals, load fluid is down by screen casing, and gravel is blocked in outside screen casing, forms gravel packing zone, liquid flows into from sieve seam, by the return flow line of washing pipe entering tool, flow into sleeve pipe from the by-pass prot on leather cup top and return to ground, complete gravel pack.Can find out that this gravel pack technics comparing is complicated, and the intensity of leather cup is low, sealing is poor, lower conversion hole cannot be closed, repeated filling weak effect.
Utility model content
The purpose of this utility model is exactly the defect for prior art, and provide a kind of structure simple, easy to use, safe stable gravel filling device, this gravel filling device not only can carry out repeated filling, and fill process is simple, still successful after repeated filling.
The concrete technical scheme of the utility model is: comprise drilling rod actuator, sleeve pipe, upper locating ring, block, centralizer, spring and lower locating ring; Described drilling rod actuator comprises drilling rod short circuit, flange, body and tapered revolving body, wherein the lower end of drilling rod short circuit connects disk body, described disk body lower end connects tapered revolving body by many standpipes, described disk body diameter is greater than the diameter of drilling rod short circuit and the surrounding of disk body is provided with multiple through hole, the surrounding of described tapered revolving body is also provided with multiple through hole, and described standpipe upper and lower side is connected with the through hole of tapered revolving body with described disk body respectively and is communicated with; The periphery of described disk body and tapered revolving body is provided with sealing ring, and described disk body and tapered revolving body stretch into sealing ring after in sleeve pipe can form slipper seal with inside pipe casing and coordinate; Upper and lower part, the periphery spacer sleeve of described sleeve pipe is equipped with locating ring, lower locating ring, and the sleeve pipe between described upper locating ring, lower locating ring is set with centralizer, spring from top to bottom successively; Casing wall corresponding to described centralizer inside has and is no less than two groups of chutes and is no less than two groups of flow path grooves; Be provided with multiple block in described sleeve pipe and each block is all connected and fixed through chute and centralizer by connector, described block and centralizer synchronously can slide up and down along sleeve pipe axis.
Such scheme is more preferably:
Described disk body is flange; Described standpipe is steel pipe.
Described chute shape is rectangle, quantity is symmetrical two, and described flow path groove shape is trapezoidal, quantity is symmetrical four.
Described connector is band self-locking nut hexagon socket head cap screw; Described sealing ring is O RunddichtringO.
The beneficial effects of the utility model are, the flexible gravel that realizes fast of spring can be utilized to fill, and can repeatedly fill, thus reduce workload, cost-saving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of sleeve pipe;
In figure: 1. drilling rod actuator, 1.1 drilling rod short circuits, 1.2 flange, 1.3 steel pipes, 1.4 tapered revolving bodies, 1.5O RunddichtringO, 2. casing coupling, 3. sleeve pipe, 4. go up locating ring, 5. block, 6. centralizer, 7. spring, 8. descends locating ring.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of gravel filling device, primarily of parts compositions such as drilling rod actuator 1, casing coupling 2, sleeve pipe 3, upper locating ring 4, block 5, centralizer 6, spring 7, lower locating rings 8.Drilling rod actuator 1 is made up of drilling rod short circuit 1.1, flange 1.2, steel pipe 1.3, tapered revolving body 1.4, the outside radiating area of the endoporus of drilling rod short circuit 1.1 and flange 1.2 endoporus and tapered revolving body 1.4 forms positive filling channel, tapered revolving body 1.4 base apertures and steel pipe 1.3 endoporus and flange 1.2 top-portion apertures form back pressure passage, and flange 1.2 is identical with tapered revolving body 1.4 external diameter and O RunddichtringO 1.5 is housed; Box cupling 2 is arranged at sleeve pipe 3 top, bottom is provided with screw thread, in the middle of sleeve pipe 3, there are 4 trapezoidal holes 3.1 symmetrical between two and 2 rectangular openings 3.2 in top position, there are upper locating ring 4 and lower locating ring 8 in the top and bottom of sleeve pipe 3, centralizer 6 is connected by 4 band self-locking nut hexagon socket head cap screws with inner 2 blocks 5 of sleeve pipe 3, hexagon socket head cap screw is through the rectangular opening 3.2 of sleeve pipe 3, centralizer 6 and block 5 can slide up and down along sleeve pipe direction, the sleeve pipe 3 outer cover spring 7 of centralizer 6 bottom, centralizer 6 and spring 7 can compress and recover between upper and lower locating ring 4,8.
When carrying out gravel and filling, descending and the contact blocks 5 of drilling rod actuator 1, the power that drilling rod actuator 1 acts on block 5 passes to centralizer 6 by hexagon socket head cap screw, power transmission is given spring 7 again by centralizer 6, spring 7 compresses under force and makes centralizer 6 relative to sleeve pipe 3 slide downward, trapezoidal hole 3.1 on sleeve pipe 3 is opened, gravel liquid flows out trapezoidal hole 3.1 by the positive filling channel of drilling rod actuator 1, complete gravel and fill link, when drilling rod actuator 1 is descending by back pressure passage release pressure, the RunddichtringO of O up and down simultaneously on drilling rod actuator prevents internal environment contaminated.During forward gravel end-of-fill, drilling rod actuator 1 is up, and spring 7 is released, and centralizer 6 blocks trapezoidal hole along sleeve pipe 3 is up, completes gravel packing operations.
