The water quantity adjustment device comprises a main machine assembly, a guide assembly and an adjustment control short section of the water quantity adjustment device, wherein a magnetic location assembly is arranged between the main machine assembly and the guide assembly, and located between the adjustment control short section and the guide assembly. With the adoption of the structure of arranging the magnetic location assembly between the main machine assembly and the guide assembly of the existing water quantity adjustment device, the magnetic location function is realized by virtue of the magnetic location assembly, and thus ensure that an operator on the ground can accurately judge the specific position of an instrument in a well, thereby increasing the measurement and adjustment efficiency of the water quantity adjustment device; and moreover, the structure of arranging the magnetic location assembly between the adjustment control short section and the guide assembly can ensure that the magnetic location assembly can accurately sense the position of the adjustment control short section of the water quantity adjustment device in an oil tube, thereby improving the operation efficiency and safety of the instrument.
Description
Technical field
The utility model relates to a kind of sensing device, especially a kind of water-quantity regulating device with the magnetic orientation function.
Background technology
Oil field development is after the later stage, and along with the continuous development of water flood recovery technology, the division of oil reservoir is more and more meticulousr, and the interval between the adjacent oil reservoir is also more and more littler.In order accurately to allocate the size of each layer water injection rate, require in oil pipe, to place a water yield gauging means.In the down-hole elastic deformation takes place owing to connect the cable of instrument, there is very big error in actual residing position in the down-hole for numerical value that the depth counter of ground cable car shows and instrument, and this error range usually can exceed the interval between the adjacent injection well downhole flow regulator.The numerical value that relies on the ground depth counter to show judges which interval instrument is in and often will produces mistake like this.The main weak point of present water-quantity regulating device is respectively:
(1) surveys to judge accurately when turning the spacing oil reservoir down whether instrument is in the position of specifying injection well downhole flow regulator, can not allocate the water injection rate of specifying interval fast and accurately, have a strong impact on instrument and survey accent efficient.
(2) carry in the process of instrument on after instrument is finished water yield allotment operation, can't judge accurately whether instrument adjusting control pipe nipple breaks away from the injection well downhole flow regulator water nozzle, causes maloperation easily, causes the major accident of Ka Jing and instrument damage.
Summary of the invention
The purpose of this utility model is: a kind of water-quantity regulating device with the magnetic orientation function is provided, and it is to overcome the deficiencies in the prior art.
The utility model is achieved in that the water-quantity regulating device of band magnetic orientation function, the host component that comprises water-quantity regulating device, guidance set, regulate the control pipe nipple, between host component and guidance set, be provided with the magnetic orientation assembly, and the magnetic orientation assembly is between adjusting control pipe nipple and the guidance set.
Total length between host component and the guidance set remains unchanged.Guarantee that water-quantity regulating device docks success rate with the guiding of injection well downhole flow regulator and can not reduce on original basis.
Guidance set and the relative distance of regulating between the control pipe nipple are constant.Can guarantee under the prerequisite of the length that does not increase new water-quantity regulating device, to possess the magnetic orientation function like this.
The composition of magnetic orientation assembly comprises two magnetic steel ingots and an induction coil, and magnetic steel ingot is in the two ends of induction coil respectively, and induction coil is connected with the main control board of host component.
Owing to adopted technique scheme, compared with prior art, the utility model adopts the structure that the magnetic orientation assembly is set between the host component of existing water-quantity regulating device and guidance set, utilize the magnetic orientation assembly to realize the magnetic orientation function, guarantee that operating personnel judge the particular location of instrument in the down-hole accurately on ground, improve water-quantity regulating device and surveyed accent efficient, and, the magnetic orientation assembly can guarantee that the accurate perception water-quantity regulating device adjusting of magnetic orientation assembly energy control pipe nipple in the residing position of oil pipe, has improved the high efficiency and the safety of instrumentation owing to placing the structure of regulating between control pipe nipple and the guidance set.The utility model adopts integrated compact design, and the magnetic orientation assembly is integrated in device inside, increases the magnetic orientation function under the prerequisite of original performance not increasing total length and do not influence.The utility model is simple in structure, and result of use is good, is applicable to the flow allocating of all layering eccentric injection mandrels of water injection well in oil fields.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of magnetic orientation assembly.
The specific embodiment
Embodiment of the present utility model: the structure of the water-quantity regulating device of band magnetic orientation function as shown in Figure 1, the host component 1 that comprises water-quantity regulating device, guidance set 2, regulate control pipe nipple 3, between host component 1 and guidance set 2, be provided with magnetic orientation assembly 4, the composition of magnetic orientation assembly 4 comprises two magnetic steel ingots 5 and an induction coil 6, and magnetic steel ingot 5 is in the two ends of induction coil 6 respectively, and induction coil 6 is connected with the main control board of host component 1; And magnetic orientation assembly 4 is in to be regulated between control pipe nipple 3 and the guidance set 2, and employing rare earth material neodymium iron boron is as the magnetic steel material of magnetic orientation assembly 4, and operating temperature can reach more than 180 ℃ not can demagnetization, has guaranteed the functional reliability of magnetic orientation assembly; Guidance set 2 and the relative distance of regulating between the control pipe nipple 3 are constant; Total length between host component 1 and the guidance set 2 remains unchanged.
In the course of the work, can produce a magnetic field between two magnetic steel ingots 5 of magnetic orientation assembly 4, in oil pipe, go downwards to the injection well downhole flow regulator place that specifies interval when the utility model, caliber can change, therefore the magnetic flux between two magnetic steel ingots 5 just changes, thereby make induction coil 6 produce induced-current, the induced-current of induction coil 6 is delivered on the main control board of the host component 1 that is attached thereto as induced signal, the terrestrial operation personnel can arrive the target interval according to this signal judgment means, afterwards will on carry device and finish and regulate control pipe nipple 3 and dock the operation of allocating with the water yield with this layer injection well downhole flow regulator water nozzle; After water-quantity regulating device is finished water yield allotment operation, on carry device, make and regulate control pipe nipple 3 and the disengaging of injection well downhole flow regulator water nozzle, carry device in the continuation, make the utility model leave this interval injection well downhole flow regulator and enter in the oil pipe, this moment, caliber changed again, and magnetic orientation assembly 4 produces an induced signal again, the terrestrial operation personnel will judge that instrument has broken away from injection well downhole flow regulator according to this signal, connect down to finish the receipts arm operation of regulating control pipe nipple 3.
