Abstract
The utility model discloses an anchoring and oil draining device of an oil pumping pipe column. The anchoring and oil draining device comprises an anchor body, a cone body, a slips, an upper sealing ring, a lower sealing ring and a sealing cylinder, wherein the cone body is spirally screwed on the thread of the anchor body; the sealing cylinder is sheathed at the outer part of the anchor body; the anchor body is provided with a communicating hole; the anchor body above the communicating hole has a small outer diameter, and the anchor body below the communicating hole has a large outer diameter; therefore, a reducing ledge can be arranged below the communicating hole of the anchor body; the upper sealing ring is located between the anchor body above the communicating hole and the sealing cylinder; the lower sealing ring is located between the anchor body below the communicating hole and the sealing cylinder; the slips is arranged between the cone body and the sealing cylinder; and one part of the slips is located in the cone body, and the other part of the slips is located in the sealing cylinder. When the pressure in the anchor body rises, the sealing cylinder goes up, and the distance between the cone body and the sealing cylinder is shortened, so that the oil pumping pipe column is anchored. When rotating the anchor body, the sealing cylinder goes up to ensure that the anchor body is communicated with a sleeve under the thread and hydraulic action of the anchor body and the cone body, thereby realizing oil drainage and disanchoring, so that an oil pipe can be lifted smoothly.
Description
Technical field
The utility model is the downhole tool that oil field pumping well is used, and is a kind of pumping pipe string grappling drainage device.
Background technology
The tubing anchor that has does not have oil draining function, is the rotatable tubing anchor of 01266815.x like the patent No., does not have oil draining function.The bleeder that has does not have the grappling function.The instrument that has has oil draining function and grappling function, but complex structure, and inconvenient operation is 02230995.0 1 kinds of Oil pipe anchoring and oil leakage devices like the patent No., and its sealing position is many, and poor reliability need be sought in the tubing string chalaza and could rotate oil pipe during draining.
Summary of the invention
The purpose of the utility model is a kind of pumping pipe string grappling drainage device of design, makes it can anchoring string, and when rotation pipeline draining.
The purpose of the utility model is achieved in that and comprises anchor body, cone, slips, goes up sealing ring, lower seal, sealing drum that cone is threaded on the screw thread of anchor body, and sealing sleeve is contained in the anchor external; The anchor body has linked hole, and the anchor body diameter on the linked hole is little, and the anchor body diameter under the linked hole is big; Make the anchor body that the reducing shoulder arranged under linked hole; Last sealing ring is between the anchor body and sealing drum on the linked hole, and lower seal is between the anchor body and sealing drum under the linked hole, between cone and the sealing drum slips is arranged; A slips part is in cone; A slips part has draining hole (8) on the sealing drum (7) in sealing drum, draining hole (8) are under the lower seal (5).
The beneficial effect of the utility model is: anchor body internal pressure raises during oil pumping, and sealing drum rises, and slips anchoring is on pit shaft, and grappling is easy, and during rotation anchor body, cone rises, and realizes disanchoring and making the linked hole UNICOM on the anchor body, realizes draining.
Description of drawings
Fig. 1 is the assembling drawing of the utility model embodiment.
The specific embodiment
Below in conjunction with Fig. 1 the embodiment of the utility model is described:
As shown in the figure, comprise anchor body 1, cone 2, slips 3, go up sealing ring 4, lower seal 5, sealing drum 7.Cone 2 is threaded on the screw thread of anchor body 1, and sealing drum 7 is sleeved on anchor body 1 outside, and anchor body 1 has linked hole 6; Anchor body 1 external diameter on the linked hole 6 is little; Anchor body 1 external diameter under the linked hole 6 is big, makes anchor body 1 that the reducing shoulder arranged under linked hole 6, and last sealing ring 4 is between the anchor body 1 and sealing drum 7 on the linked hole 6; Lower seal 5 is between the anchor body 1 and sealing drum 7 under the linked hole 6; Between cone 2 and the sealing drum 7 slips 3 is arranged, slips 3 parts are 2 li of cones, and slips 3 parts are 7 li of sealing drums.Draining hole 8 is arranged on the sealing drum 7, and draining hole 8 is under the lower seal 5.
When the utility model was gone into the well the back oil pumping with oil pipe, anchor body 1 internal pressure raise, and hydraulic pressure imports in the annular space between sealing ring 4, the lower seal 5 in anchor body 1; Make sealing drum 7 produce upwards thrust, last thrust is during greater than the ability to bear of fixing pin 8, and fixing pin 8 quilts are cut off; Sealing drum 7 is up; Reduced distances between cone 2 and the sealing drum 7, slips 3 are opened under cone 2 effects and are anchored on the sleeve pipe, and pumping pipe string is anchored.When oil pipe was carried in the oil well operation, rotation pipeline made 1 rotation of anchor body, under slips 3 effects; Cone 2 is not rotated, and under the threaded function of anchor body 1 and cone 2, makes between cone 2 and the anchor body 1 and produces relative motion; Under the hydraulic action in anchor body 1, sealing drum 7 is up thereupon, behind sealing drum 7 up certain altitudes; The draining hole 8 on the sealing drum 7 or the lower surface of sealing drum 7 are increased on the lower seal 5, make anchor body 1 and sleeve pipe UNICOM, thereby realize draining.Behind the draining, oil pipe, casing pressure balance, sealing drum 7 is no longer up, and slips 3 leaves sleeve pipe and regains, and realizes disanchoring, and oil pipe can propose smoothly.
Prevent that sealing drum 7, slips 3 inactive way when going into the well from also can take other multiple way except that adopting fixing pin, as adopting spring etc.
For reducing difficulty of processing and economical with materials, anchor body 1 can adopt many parts to be combined into one.
