It is provided with radial annular distance 16 on the periphery of set 4（Referring to Figure of description 3）.
After one end of the conductive coil 12 wound on iron core 11 passes through assembly inner sleeve 4 by coil guide groove 15, connect through cable
The inside for sealing inner sleeve 20 is entered after receiving the lead set 18 of device A9（Referring to Figure of description 2）；The other end of conductive coil 12
It is passed through by coil guide groove 15 and is entered in sealing inner sleeve 20 after the lead of cable receiver B10 set 18 after assembling inner sleeve 4
Portion.
Pass through radial annular distance 16 and radially connected hole into the conductive coil 12 in the sealing inner sleeve 20 of cable receiver B10
After 21, enter inside the sealing inner sleeve 20 of cable receiver A9；Into the 12 both ends end of conductive coil of cable receiver A9
Outer end is extended to by the coil inlet and outlet 14 being arranged on shell 1.Extend to the both ends end of the conductive coil 12 of outer end with it is outer
The cable connection on boundary.
It assembles in inner sleeve 4 and rotary core shaft is equipped with by alignment bearing 5 and turbine 6（Referring to Figure of description 1）；Rotary core shaft
It is made of shunt head 7, mandrel ontology 22, sectioned coil 23 and metal guide rod 24, mandrel ontology 22 is multi-diameter shaft, mandrel ontology 22
One end by fittings body 25 be equipped with shunt head 7；7 tapered body of shunt head（Referring to Figure of description 12）, shunt head 7 is such
The purpose of setting is：, can be evenly dispersed along the conical surface of shunt head 7 so that after flushing liquor enters top connection 2, and from turbine
It is flowed uniformly through in 6；And then 7 end face of shunt head is avoided in the problem that dispersion unevenness occurs when other shapes.
It is fixed with metal guide rod 24 in the fittings body 25 of 7 side of shunt head（Referring to Figure of description 12）；Mandrel ontology 22
The other end be fixedly connected with lower contact 3 and Flushing nozzle 8；It is evenly arranged with multiple streams on the other end circumference of mandrel ontology 22
Through-hole 26；Each recirculation hole 26 is connected to the diversion pipe 31 of Flushing nozzle 8.
The thick end portion of mandrel ontology 22 is evenly arranged with multiple T shapes winding slots 27（Referring to Figure of description 5）；T shapes around
Wire casing 27 is corresponding with iron core 11.The sectioned coil 23 of 27 inner wrap of T shapes winding slot can so be made, be located at the interior of iron core 11
Portion, and then when making work, the sectioned coil 23 of rotation can cut the magnetic line of force of 11 internal magnetic field of iron core.
Sectioned coil 23 is by each T shapes winding slot 27 laterally around being connected on mandrel ontology 22；The both ends end of sectioned coil 23
Head is connect by the intercommunicating pore being arranged on mandrel ontology 22 with the both ends of metal guide rod 24 respectively.So in the work of metal guide rod 24
Under, sectioned coil 23 forms the circuit of a closure, and when it is in 22 rotation process of mandrel ontology, sectioned coil 23 can be cut
The magnetic line of force in assembly inner sleeve 4 is cut, the torque for hindering 22 rotation of mandrel ontology can be so generated.Magnetic in assembly inner sleeve 4
When field is stronger, the obstruction torque that 23 cutting magnetic line of sectioned coil generates is bigger, and the rotating speed of mandrel ontology 22 will decrease；
Otherwise the rotating speed of mandrel ontology 22 will increase.And assemble the magnetic field size in inner sleeve 4 can by adjust conductive coil 12 electric current
Size controlled, so can reach and reach control mandrel ontology 22 by regulating and controlling the means of 12 size of current of conductive coil
The purpose of rotating speed.
When the controllable rotational flow flushing tool work of the rotating speed, the flushing tool is connected to continuously by top connection 2 first
On oil pipe pipe string, shaft bottom is then transferred to by coiled tubing pipe string.
High pressure washing liquid is then pumped into the flushing tool by coiled tubing pipe string；After flushing liquor enters top connection 2, edge
The conical surface for shunt head 7 evenly spreads to mandrel ontology 22 and assembles in the annular space between inner sleeve 4, and impulse turbine 6 makes its band
Moving mandrel's ontology 22 rotates, and drives diversion pipe 31, lower contact 3 and sprayer body 28 to rotate synchronously in 22 rotation process of mandrel ontology.
In this course, after flushing liquor passes through turbine 6, the inside of diversion pipe 31 is entered through recirculation hole 26；Into leading
A part of flushing liquor inside flow tube 31 cleans pipe well in the ejection of eddy flow shape to nozzle 30 through preceding；At the same time another portion
Flushing liquor is divided to be sprayed into inside sprayer body 28 by eddy flow branch pipe 32；It is in through swirl nozzle 29 into the flushing liquor inside sprayer body 28
The tube wall of pipe well is cleaned in the ejection of eddy flow shape.
In the flushing tool course of work, since eddy flow effect is more demanding to rotating speed, only in certain range of speeds
Rotational flow flushing effect is just more preferable, and different model oil well requires the rotating speed of flushing tool different.In order to reach best cleaning effect
Fruit and energy-saving effect, the flushing tool are also different in the optimum speed of different model oil well.
When the flushing tool is when needing to reduce mandrel 22 rotating speed of ontology, increasing flows through the current strength of conductive coil 12,
To make to form magnetic field intensity reinforcement in assembly inner sleeve 4；The obstruction torque that 23 cutting magnetic line of sectioned coil generates at this time is got over
Greatly, the rotating speed of mandrel ontology 22 decreases；At the same time also it can coordinate reduction mandrel in such a way that flow velocity is rinsed in reduction
The rotating speed of ontology 22, the mode due to reducing flushing flow velocity have the inaccurate problem of manipulation therefore can only be used as supplementary means
It uses.When the flushing tool is when needing to increase mandrel 22 rotating speed of ontology, reduction flows through the current strength or liter of conductive coil 12
Height rinses flow velocity and increases turbine discharge capacity.
The controllable rotational flow flushing tool of the rotating speed, it is simple in structure, ingenious in design, solve the speed that existing flushing tool has
The problem that control range is small, complex procedures caused by the frequent transformation of needs and labor intensity are big is spent, enterprise's production and application is met
Needs.
