Abstract
The invention relates to the petroleum machinery and discloses an electric salvage device. A device body (1) is provided with a rope socket (2), a guide head (3), a guide detent (4), a guide cam assembly (5), a salvage body (6), a salvage detent (7) and an upper cam assembly (8). A control unit composed of a driving mechanism, a controller (9) and a battery (10) is arranged in the body (1). The driving mechanism comprises a driving motor (11), a screw rod (12) and a moving sleeve (13), wherein the moving sleeve (13) can slide in a pipe cavity of the body (1) along with the rotation of the screw rod (12). The salvage body (6) is fixed at the lower end of the moving sleeve (13), and a positioning cam assembly (14) and a positioning detent (15) are arranged below the salvage detent (7). According to the electric salvage device, the salvage testing distance is shortened effectively, the testing distance is changed to be 1 meter from the prior 5 meters, and the device is adapted to subdivision requirements of water wells, and a reliable guarantee is provided for further fine subdivision of water injection.
Description
Technical field
The present invention relates to petroleum machinery, particularly a kind of electric fishing device that shortens down-hole dropping-fishing test distance.
Background technology
The operation process of tradition throw in catcher is carried on normally throw in catcher being transferred to behind the predetermined well depth (cross injection well downhole flow regulator 2-3 rice), transfer again after crossing injection well downhole flow regulator seating nipple 4-5 rice, make the pulling pawl under the effect of guiding device and descending impulse force, accurately blanking plug is dropped into or pulls out.
Along with the oil field subdivision injection, the part substratum is effectively enabled, and it is more and more less that compartment thickness becomes, have at 5-10 rice, have at 2-3 rice.Conventionally test technique just can not satisfy the test needs for this problem.Change test technology, supporting testing tool has just become the task of top priority with it.If adopt pulling process under the electronic control well, then can realize accurate control.
Summary of the invention
Technical problem to be solved by this invention is: for the problems referred to above, provide a kind of electric fishing device that shortens the dropping-fishing test distance.
Technical solution of the present invention is: it comprises body, the body top is provided with rope socket, the lower end is provided with guide head, guide grab, the guide cam assembly, the pulling main body, the overhead cam assembly of pulling pawl and the action of control pulling pawl, the pulling pawl is hinged on the pulling main body and by spring force and launches, be provided with by driving mechanism in the tube chamber of described body, the control device that controller and battery consist of, driving mechanism comprises drive motors, what be connected with motor shaft below drive motors can be with the screw mandrel and the movable sleeving that is enclosed within outside the screw mandrel of drive motors rotation, the movable sleeving upper end is provided with the screw section that cooperates with screw mandrel, movable sleeving can slide in the body tube chamber with the rotation of screw mandrel, described overhead cam assembly place is provided with magnetic patch and the sensor for detection of the cam state, described pulling main body is fixed on the movable sleeving lower end and can slides up and down with it, body is provided with the positioning cam assembly and opens with the cam upset in the below of pulling pawl locating detent, battery, drive motors and sensor are electrically connected respectively with controller.
Technique effect of the present invention is: it has effectively shortened the dropping-fishing test distance, makes former traditional measuring distance more than 5 meters become 1 meter, adapts to the needs of well segmentation, for the further meticulous subdivision injection in oil field provides Reliable guarantee.
Description of drawings
Fig. 1 is sectional structure schematic diagram of the present invention.
The specific embodiment
As shown in Figure 1, it comprises body 1, body 1 top is provided with rope socket 2, the lower end is provided with guide head 3, guide grab 4, guide cam assembly 5, pulling main body 6, the overhead cam assembly 8 of pulling pawl 7 and 7 actions of control pulling pawl, pulling pawl 7 is hinged on the pulling main body 6 and by spring force and launches, described body 1 is provided with by driving mechanism in the tube chamber of guide head 3 belows, the control device that controller 9 and battery 10 consist of, driving mechanism comprises drive motors 11, what be connected with motor shaft below drive motors 11 can be with the screw mandrel 12 and the movable sleeving 13 that is enclosed within outside the screw mandrel 12 of drive motors rotation, movable sleeving 13 upper ends are provided with the screw section that cooperates with screw mandrel 12, movable sleeving 13 can slide in body 1 tube chamber with the rotation of screw mandrel 12, described overhead cam assembly 8 places are provided with magnetic patch and the sensor for detection of the cam state, described pulling main body 6 is fixed on movable sleeving 13 lower ends and can slides up and down with it, body 1 is provided with positioning cam assembly 14 and opens with the cam upset in the below of pulling pawl 7 locating detent 15, battery 10, drive motors 11 and sensor are electrically connected respectively with controller 9.
Described body 1 is connected to battery sleeve 16 in rope socket 2 lower end snails, and battery 10 is located in the battery sleeve 16.
The position of described body 1 on movable sleeving 13 is bolted with motor cylinder 17, and drive motors 11 and controller 9 are fixed in the motor cylinder 17.
The present invention is reasonable in design, compact conformation, and wire is connected with device by wire casing and the conduit that is opened on the tube wall.
Existing job step: carry on transferring to throw in catcher behind the predetermined well depth (crossing injection well downhole flow regulator 0.5-1 rice), transfer again after crossing 1 meter of injection well downhole flow regulator seating nipple, locating detent is parked in injection well downhole flow regulator support place, and electric motor starting makes the pulling pawl come downwards to inclined to one side hole in gathering sill, finishes and drops into or pull out blanking plug.
Launch process: with the blanking plug pressing and sending head of packing into, load onto battery after, circuit can be judged pulling pawl position, if not playback, first playback.To be pressed into pocket with the pulling pawl of blanking plug, stir pulling pawl cam, the pulling pawl will be pinned.With winch instrument is sent in the well, after arriving designated layer position (crossing injection well downhole flow regulator 0.5-1 rice), on carry instrument, three cams are the upset that is triggered simultaneously of predetermined station in the down-hole, guide grab 4, pulling pawl 7 and locating detent 15 are opened, provide signal by the magnet that studs with on the top jaw, timing begins, send under the instrument to make locating detent 15 sit on the support position location, the instrument motor is started working, and pressing and sending head 19 is descending under the promotion of leading screw, blanking plug 18 is advanced in the inclined to one side hole of main body, shift behind the position (number of turns control that is turned by motor) onto and stop descendingly, timing rear motor counter-rotating in 3 seconds leading screw drives on the pressing and sending head 19 and moves, and returns to initial position.The salvaging process only need to be replaced with fishing head with pressing and sending head 19 and get final product.
