Abstract
The utility model discloses a connecting structure for power cables in fisher movement components. The connecting structure comprises a motor driving a movement component to reciprocate axially along an outer tube and a limit switch disposed on a lower fishing release arm of the movement component. The motor and the limit switch are connected with a cable which is spiral. The spiral cable is located in a gap between a mandrel and the outer tube. The movement component in an underground fisher is powered through the spiral cable; when the movement component in the fisher moves axially along the outer cylinder of the fisher, retractability of the spiral cable allows the cables in the fisher to be arranged in order, the cables are prevented from being broken or snapped and powering reliability is guaranteed. The method is simple and practical, the connecting structure can be conveniently laid out in an elongated tubing type outer tube, and the connecting structure is suitable for wiring of downhole instruments.
Description
Technical field
The utility model relates to a kind of fisher motion assembly electricity cable syndeton, belongs to downhole instrument power supply technique field.
Background technology
Oilfield exploitation needs to adopt the mode to the stratum displacement of reservoir oil by filling water to guarantee crude output after the later stage.Water injection rate is mainly by the realization of stopper for regulating openings of sizes, and each the adjusting needs to adopt fisher that blanking plug is got up from underground fishing, mixes up and is sending into the down-hole afterwards, so the input of blanking plug and the routine work of salvaging the production that is an oil well.
But existing fisher can only once be thrown in a blanking plug or salvage a blanking plug, inefficiency, and workload is large, in order to raise the efficiency present many blanking plugs of an a kind of intelligent throw in catcher pulling of energy of having developed.According to the function needs, the input arm component in fisher is the motion assembly, can need within the outer tube to move back and forth vertically, therefore also should be able to move together with the motion assembly with four current supply lines throwing in the arm component connection.
Summary of the invention
The purpose of this utility model is, a kind of fisher motion assembly electricity cable syndeton is provided, and powers to realize the mobile of motion assembly, thereby overcomes the deficiencies in the prior art.
The technical solution of the utility model is to consist of like this: a kind of fisher motion assembly electricity cable syndeton of the present utility model is that this structure comprises that the actuation movement assembly is along outer tube the axial reciprocating motor that moves and the travel switch that is located on the assembly bottom salvaging input arm that moves; Motor is connected with cable with travel switch, and cable is helical form, in the gap of spiral cable between mandrel and outer tube.
In aforementioned electric supply installation, described motor is connected with cable through sealing-plug.
Compared with prior art, the utility model is motion assembly power supply in underground fishing tool by spiral cable, when moving axially, the fisher urceolus utilize the scalability of spiral cable to make the arrangement in good order of fisher inner cable when motion assembly in fisher, can prevent that cable is extruded breaks or breaks, to guarantee power supply reliability.Method simple practical of the present utility model is convenient to arrange in the outer tube of elongated tubular product, is applicable to the downhole instrument wiring.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Being labeled as in figure: 1-motor, 2-salvage and throw in arm, 3-cable, 4-mandrel, 5-outer tube, 6-sealing-plug.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, but not as to any restriction of the present utility model.
The utility model is constructed according to the method for supplying power to of motion assembly in following a kind of underground fishing tool, as shown in Figure 1, the method is passed through motor-driven with the motion assembly, in the method, motor is connected with cable by sealing-plug, in the gap of cable winding between mandrel and outer tube in the shape of a spiral, when moving along the outer tube axial reciprocating under the drive of motion assembly at motor, utilize the scalability maintenance of helical form cable to the reliable power supply of motion assembly.
In preceding method, described helical form cable adopts the four-core spiral cable, four driving powers that are connected with motor as the motion assembly, and other two are connected with travel switch, as salvaging the location index signal line of throwing in arm.
The structural representation of the of the present utility model a kind of fisher motion assembly electricity cable syndeton that builds according to said method as shown in Figure 1, this structure comprises the motor 1 that the actuation movement assembly moves along the outer tube axial reciprocating and is located at the assembly bottom of moving salvages the travel switch of throwing on arm 2; Motor 1 is connected with cable 3 with travel switch, and cable 3 is helical form, in the gap of spiral cable between mandrel 4 and outer tube 5.Motor 1 is connected with cable 3 through sealing-plug 6.
Salvaging input arm 2 in the utility model opens under motor 1 is controlled, and salvages or throws in blanking plug, and after docking successfully, salvaging or launch process need to be salvaged input arm 2 and move up and down, and realize salvaging or input to blanking plug.Two wires that are connected with motor 1 need to pump, and throw in salvaging to also have the one stroke switch on arm 2, are used for the stroke detection judgement, and totally four wires need reciprocating motion.Now cable 3 is made the four-core spiral cable, be connected by four wires in sealing-plug 6 and bottom, salvage input arm 2 and lower component and pump, the four-core spiral cable, flexible in outer tube 5, move back and forth, the realization motion is powered.
