Abstract
The utility model discloses a down -hole junk slip socket can salvage the oil industrial oil well short pole pipe type junk of length in the pit. This salvage section of thick bamboo is including top connection, slips and barrel, and the top connection is equipped with the pressure release hole, and the slips inner wall is equipped with slip insert, the inner chamber of barrel be down little, go up big toper chamber, the slips is installed in the toper chamber of barrel, the spring is equipped with in top connection and barrel threaded connection between top connection and slips. The utility model discloses a short and small junk of length provides effectual fishing tool in the pit, has apparent result of use.
Description
Technical field
This utility model belongs to the device for fishing drops underground of petroleum industry, particularly a kind of trouble of lost tool in hole slip socket, it is possible to salvage the rod tube class junk that down-hole length is shorter.
Background technology
The most conventional returnable slip overshot is the fishing tool grabbed from fish external diameter and drag for fish.It can salvage drill collar, drilling rod, oil pipe, joint, box cupling and other well tube.This series of tools complete function, has sealing structure, can carry out mud circulation after engagement with the fish.If the fish caught is by card, also can be easy to withdraw, the most also with milling shoe, can effectively repair top of fish breach, overlap, it is simple to fish enters dipper smoothly.If needing to increase net to drain the pasta and long-pending can connect increasing guide shoe, during the top of fish bias borehole wall, wall hook can be used, grabbing and dragging for position and the farthest can increase away from top of fish and connect extension.Although returnable slip overshot is of a great variety, but still it is weak during for special circumstances.Use drag for lance salvage give up bridge envelope during, it is possible that the situation that shaft comes off, cause second accident, owing to cannot drag in carrying out, simultaneously because the shaft length exposed is shorter, general slip socket cannot be salvaged again.If salvaging unsuccessful, oil well will face the risk closed down, and the loss and the impact that cause also are huge.Production scene needs to manufacture the fishing tool salvaging short and small rod tube class junk.
Summary of the invention
The purpose of this utility model is to provide a kind of trouble of lost tool in hole slip socket, completes the salvage of the shorter rod tube class junk of length, reduces workover treatment cost, improves productivity effect.
This utility model is achieved in that a kind of trouble of lost tool in hole slip socket includes top connection, slips and cylinder, top connection is provided with relief hole, slips inwall is provided with slip insert, the inner chamber of cylinder big conical cavity little under being, upper, slips is arranged in the conical cavity of cylinder, top connection is connected with cylinder screw, equipped with spring between top connection and slips.
Compared with prior art, the beneficial effects of the utility model are: it is slips that the grabbing of this fishing socket drags for parts, its internal slip insert is left-handed pawl card tooth, slips cylindrical and cylinder lumen are all pyramidal structures, its fit-up gap is bigger, cylinder big conical cavity little under having, upper, thus can make the slips of conical external circle have the up swell of certain stroke and the descending process reduced in cylinder.After fish is introduced into cylinder, as long as being downwardly applied to an axial compressive force, slips just can be up in cylinder, and axial compressive force makes fish enter slips.Now up due to slips and swell, can use hard sharp slip insert and borrow the effect of elastic force to be bitten by fish and clamping.When upper lifting pipe post, slips relatively moves downward in cylinder, because the vertical section of left-handed pawl card tooth is tapered slope, slips inevitable with heavy fish to the lower motion of cylinder, now the weight of fish is bigger, card the tightest, whole weight is passed to cylinder by slips.Being proved by field experimentation, this utility model is highly suitable for:
1, the fishing of top of fish intracavity fish head, can salvage the rod tube class junk of the release diameter 46mm 52mm without being hampered, tensile strength 30KN at fish intracavity.
2, slips can be changed according to fish head situation, be adapted to the fishing of different fish by the size of conversion slips.The maximum rod tube class junk that can salvage the release diameter 54mm 62mm without being hampered, can drag for the shortest top of fish obtained is 200mm, tensile strength 30KN.
This utility model is that length short and small junk in down-hole provides effective fishing tool, has significant using effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with detailed description this utility model, and unrestricted protection domain of the present utility model, the improvement that all uses mentality of designing of the present utility model draws belongs to protection category of the present utility model.
See Fig. 1, a kind of trouble of lost tool in hole slip socket includes top connection 1, slips 3 and cylinder 4, top connection 1 is provided with relief hole, slips 3 inwall is provided with slip insert, the inner chamber of cylinder 4 big conical cavity little under being, upper, slips 3 is arranged in the conical cavity of cylinder 4, and top connection 1 is threadeded with cylinder 4, equipped with spring 2 between top connection 1 and slips 3.The bottom cylindrical of slips 3 body is that conical external circle matches with the conical cavity of cylinder 4, body is the most at least cut into two at upper cut hole, and the slip insert of slips 3 inwall is left-handed pawl card tooth.The tapering of the conical cavity of cylinder 4 and the conical external circle of slips 3 is set between 13-17.The lower surface of top connection 1 and the upper surface of slips 3 are provided with two coil spring seat slot, equipped with inside and outside two groups of springs 2 between top connection 1 and slips 3, it is ensured that the job stability of slips 3.The lower body of cylinder 4 is provided with horn mouth, can use as guide shoe, makes fish be easily accessible in this instrument.
