Abstract
The utility model discloses an FOX oil pipe locating device, which comprises an oil pipe body and a slip type seating and hanging part, an FOX oil pipe adopts a slip mode to be directly seated and hung at the inner wall of the oil pipe, the oil pipe coupling is not needed, and the seating and hanging at any point in the pile pipe can be realized. Because the slip type seating and hanging effect is better. The FOX oil pipe locating device has the advantages that the structure is simple, the design is reasonable, the use is convenient, the cost is low, the FOX oil pipe can be directly seated and hung at any point of the inner wall of the oil pipe, the work efficiency is improved, and the large-area popularization and use can be easily realized.
Description
Technical field
The utility model relates to a kind of oil gas well downhole hardware, is specifically related to a kind of FOX oil pipe and is located device.
Background technology
The domestic following card mode of the tubing coupling below instrument that utilizes usually, inconsistent because of the tubing coupling gap size, often cause being located inefficacy.And FOX tubing coupling slit is narrower, and the common device that is located adopts coupling type to sit extension, and relatively poor because of the narrower effect of FOX box cupling, the instrument of can not effectively transferring is sat and hung.Therefore, be badly in need of a kind of oil pipe that is directed against the stability and high efficiency of FOX oil pipe on the market and be located device.
The utility model content
To the problems referred to above, it is a kind of simple in structure, with low cost that the utility model provides, and the FOX oil pipe that can use for a long time is located device, effectively improved FOX oil pipe instrument and be located accuracy and efficiency of construction.
The technical scheme that the utility model adopts is:
A kind of FOX oil pipe is located device, comprises oil pipe body and slip-type seat extension portion, and it is characterized in that: said slip-type is sat extension portion and comprised built-in slips, slip spider, body; Built-in slips is positioned at slip spider, and the slip spider lower end is designed with outer step, and seat is on the interior step of body; The slips hold-down screw is fixed on built-in slips on the snap ring; Be evenly equipped with the screw hole identical with slips quantity on the snap ring, be designed with laterally zygomorphic two pin-and-holes at the shackle openings place, lock pin is inserted in the pin-and-hole; The lock pin upper end is processed with a lacing hole, and the slip spider correspondence position also is provided with through hole.
The structure design that the utility model adopts snap ring to cooperate with lock pin; Can put on rope by the lacing hole of lock pin; Extract the state of lock pin control spring lock ring through control, thereby realize away from well head control sleeve pipe suspension operation, the safety when having guaranteed the sleeve pipe suspension operational.
Compared with prior art, the advantage of the utility model is:
The utility model is simple in structure, and is reasonable in design, easy to use, with low cost, and the instrument that can increase substantially is located accuracy, increases work efficiency, and is easy to large tracts of land and promotes the use of.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 sits the partial structurtes sketch map of extension portion for the utility model slip-type.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further explained.
A kind of FOX oil pipe as shown in Figure 1 is located device, comprises oil pipe body (8) and slip-type seat extension portion (9).As shown in Figure 2, said slip-type is sat extension portion (9) and is comprised built-in slips (3), slip spider (4), body (5), and built-in slips is positioned at slip spider; The slip spider lower end is designed with outer step; Seat is on the interior step of body, and slips hold-down screw (1) is fixed on built-in slips (3) on the snap ring (2), is evenly equipped with the screw hole identical with slips quantity on the snap ring (2); Be designed with laterally zygomorphic two pin-and-holes at the shackle openings place; Lock pin (6) is inserted in the pin-and-hole, and the lock pin upper end is processed with a lacing hole, and the slip spider correspondence position also is provided with through hole.
The structure design that the utility model adopts snap ring to cooperate with lock pin; Can put on rope by the lacing hole of lock pin; Extract the state of lock pin control spring lock ring through control, thereby realize away from well head control sleeve pipe suspension operation, the safety when having guaranteed the sleeve pipe suspension operational.
Though the utility model is described with reference to aforesaid specific embodiment; But those skilled in the art will be appreciated that; Above embodiment only is in order to explanation the utility model rather than restriction the utility model, as long as in the scope of in the connotation scope of the utility model, the variation of the foregoing description, claims that modification all should fall into the application being asked for protection.
