Abstract
The utility model discloses the de-disconnected device of a kind of rod string; comprise center-pole; the two ends of center-pole are all threaded connection a connector, and 2 connectors are socketed with a sleeve respectively by helicitic texture, the outer surface cover of center-pole have protection center-pole meet dish a and cover meets dish b.Achieve oil well pump stuck after, pulling force between rod string increases, the de-disconnected device fracture connected between rod string; thus the object of protection rod string; and make rod string easily pull out well face, facilitate the maintenance of rod string, improve the operating efficiency of rod string.
Description
Technical field
The utility model belongs to oil development and downhole tool technical field, is specifically related to the de-disconnected device of a kind of rod string.
Background technology
Existing rod string is the pulling head of going into the well with rod string mostly, and is split-type spring detent structure, but the de-disconnected device connected between existing rod string exists the problem by collision mutability in transport and process of going into the well.And in oil well in oil pumping process, there is the stuck situation of oil pump piston sometimes, when oil pump piston is stuck, rod string can be made to be subject to very large pulling force, thus cause rod string to rupture, cause very large economic loss, and affect the normal production of oil well.
Utility model content
The purpose of this utility model is to provide the de-disconnected device of a kind of rod string, solves the problem breaking rod string when oil pump piston is in stuck state existed in prior art.
The technical scheme that the utility model adopts is; the de-disconnected device of a kind of rod string; comprise center-pole; the two ends of center-pole are all threaded connection a connector; 2 connectors are socketed with a sleeve respectively by helicitic texture, the outer surface cover of center-pole have protection center-pole meet dish a and cover meets dish b.
Feature of the present utility model is also,
Wherein connect stop pad dish a being provided with and preventing from connecing dish a slip.
Wherein 2 sleeve socket rod strings.
Wherein the diameter of center-pole is less than the diameter of connector.
Wherein meet dish a and connect between dish b and be connected with pull bar.
Wherein the two ends of pull bar all connect a center-pole connector, and 2 center-pole connectors are coiled b by screw device be connected respectively at meeting dish a and connecing.
The beneficial effects of the utility model are, 2 sleeve connection rod strings, and be connected with center-pole between 2 sleeves, center-pole bears the pulling force of rod string, center-pole is connected to meeting dish a and meeting dish b of protection center-pole by thread bush, and meet dish a and connect stop pad and pull bar that dish b is arranged, center-pole is prevented to be made center-pole impaired by oil pollution, reduce application life and holding capacity reduction, stop pad and pull bar can prevent from meeting dish a and meeting dish b rotating, make its protected effect better, 2 sleeves are by helicitic texture connecting with pumping rod post, when oil well pump is stuck, center-pole can be broken or pull sleeve, make to avoid breaking rod string, and enable rod string be drawn out well face, carry out failture evacuation.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of rod string of the utility model takes off disconnected device;
Fig. 2 is the structural representation that a kind of rod string of the utility model takes off center-pole in disconnected device.
In figure, 1. connector, 2. sleeve, 3. connect dish a, 4. pull bar, 5. connects dish b, 6. stop pad, 7. center-pole, 8. center-pole connector.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model provides the de-disconnected device of a kind of rod string, as Fig. 1, shown in 2, comprise center-pole 7, the two ends of center-pole 7 are connected with connector 1 respectively by helicitic texture, 2 outer sleeves 2 being had protection connector 1 by thread bush of connector 1, sleeve 2 connecting with pumping rod post, and the diameter of center-pole 7 is less than the diameter of connector 1, and central post 7 is outer is socketed with meeting dish a3 and meeting dish b5 for the protection of central post 7 by helicitic texture, connect on dish a3 and have the square stop pad 6 preventing from connecing dish a3 rotation, and connect dish a3 and connect dish b5 between be connected with pull bar 4, pull bar 4 two ends all connect a center-pole connector 8, 2 center-pole connectors 8 meet dish a3 respectively by helicitic texture and meet dish b5.
The using method that a kind of rod string of the utility model takes off disconnected device is, 2 rod strings are connected in 2 sleeves 2, then will meet dish a3 and meet dish b5 is connected on center-pole 7, center-pole 7 is connected between 2 sleeves 2, then stop pad 6 is arranged on connect dish a3, and pull bar 4 is arranged on connect dish a3 and connect dish b5 between.
Use the de-disconnected device of a kind of rod string of the utility model; make the rod string no longer load-bearing coupled together; the de-disconnected device connected between sucker rod bears pulling force; and meeting dish a3 and meeting dish b5 to protect center-pole 7 injury-free; when oil well pump is stuck, the pulling force between rod string is increased, and can not rod string be hurt and make the fracture of de-disconnected device; thus protect rod string, prevent the fracture of rod string.
