Description
Technical field
The present invention relates to a kind of electric immersible pump well wax-proofing apparatus, more particularly to a kind of electric immersible pump well electromagnetic induction wax-proofing apparatus.
Background technology
Oil well paraffinication be for a long time at home and abroad oil extraction process the problem of, be extracted by subterranean layer in crude oil
When ground, since the expansion of underground gas volume causes crude oil temperature to decline, along with molecular weight of the wax in crude oil is different
, because the change carburetion wax of temperature can be precipitated according to the different order of molecular weight, then due to gravitional force in recovery process
It is deposited on oil pipe, the socket of original pipeline is made to become narrow, block pipeline, crude output reduces, or even oil well is caused to stop production.
Currently, the common paraffin removal and control method for oil well in oil field mainly has mechanical Paraffin Removal, heating power Paraffin Removal, surface energy wax control
(liner and coating tubing) chemical agent Paraffin Removal, strong magnetic Paraffin Removal and microbial wax control etc..
1 mechanical paraffin removal technology：By paraffin removal tool G.I.H, the wax on tubing wall is struck off, and wax is brought to ground by liquid stream
Face.The paraffin removal tool used in flowing well is mainly by paraffin scraper and paraffin bit etc..Paraffin scraper is used under normal circumstances, if
Wax is serious, then uses paraffin bit；
2 heating power Paraffin Removal technologies：Heating power Paraffin Removal technology is to improve one kind that wellbore fluids temperature reaches Paraffin Removal using thermal energy
Method.Oil well paraffin prevention is then played when crude oil temperature is more than wax precipitation temperature for wax crude oil；When temperature is more than the fusing point of wax
When, then play the role of paraffin removal from oil well.For the solidifying oil of height and viscous crude, then the thermally sensitive characteristic of its mobility is utilized, well is passed through
Cylinder heating achievees the purpose that viscosity reduction drop resistance.Heating power Paraffin Removal technology is divided into heat carrier cycle according to its heat medium difference and electricity adds
Hot two major classes；
3 chemical agent Paraffin Removal technologies：It is the relatively broad one kind of current field use to carry out Paraffin Removal to oil well with chemical agent
Technology does not influence oil well normally production and other operations, removing can this is because usually injecting medicament from oil casing annular space
To receive outside Paraffin Removal effect, pour point depression, viscosity reduction and the effect of de-plugging can also be received using certain medicaments；
4 oil tube inner linings and coating wax control：The smoothness of tube wall can be improved in oil tube inner lining and coating wax control, improves surface wettability
(reach it is hydrophilic hate make wax be not easy to deposit, to achieve the purpose that wax control；
5 microbial wax controls：Microorganism actively moves about to food such as paraffin, hydrocarbon direction, hydrocarbon by being saturated in crude oil
Compound, gum asphalt degradation, reduce the paraffin content in crude oil, to inhibit the deposition of paraffin；
The last 6 magnetic Paraffin Removal：Crude oil is the mixture and diamagnetic substance of various hydrocarbon complex in composition.When crude oil is by reaching
When the magnetic field of sufficiently large magnetic field intensity and gradient, due to the effect of Lorentz force so that be in unordered heat near crystallization temperature
Wax molecules in movement, obtain energy, have adjusted mutual magnetic and hit orientation, provide universal crystallization life core condition, from
And a large amount of diameter very littles are generated, it is in spherical crystallite（It is the 1/10000 of common wax crystalline substance diameter）It is suspended in crude oil, in this way
Be largely reducing pipe keep away and sucker rod on analysis bear sheet hard wax, and the netted complexing of scale paraffin is formed in crude oil
The possibility of object also just reduces the flow resistance of crude oil simultaneously.
What the present invention mainly inquired into is the heating power Paraffin Removal technology of electric immersible pump well, that is, by nearby being carried out to wax deposition point
Heating works to complete wax control, since in electric immersible pump well, the device structure of electric submersible pumping is simple, efficient, discharge capacity is big, certainly
The advantages that dynamicization degree is high is widely used in non-blowing high-yield well, high water-cut well and offshore oilfield, becomes stable and high yields and warp
One of preferable artificial lift mode of benefit of helping, is one of the main means adopted by force the oil exploitation case middle and later periods.
And in the work of the wax control of electric submersible pump, generally using electrical heating and infiltration two ways, wherein electrical heating is usually
Annular space between the casing and flow string under ground installation lower going-into-well, electric heater unit are installed near wax deposition point, cable
Line is connected to ground installation by annular space, since electric heater unit can only be by being heated, in this way, heat on the outside of flow string
The inner cavity that flow string can be just transmitted to across flow string is needed, this needs to consume a large amount of electric energy, and effect is not fine,
In addition, it is also necessary to which the special cable spacer of tripping in, not so sealing effect is bad, and is used for the cable spacer of electric submersible pump with regard to valence
Lattice are expensive, and import is a set of to be needed to spend 170,000 RMB, need replacing the cable spacer for paired cable, price costly,
In addition, still there is some potential safety problems in the underground of several kms of cable tripping in because, when going into the well cable it is easy to wear by
Wound causes its short circuit or service life to decline, although the cable of existing electric submersible pump is all provided with cable protective sleeve, originally
It is piece cable of card, it is now desired to block 2, this just needs worker to be changed to strain relief clamp, complicated for operation, and difficulty of construction adds
Greatly, moreover, there are various security risks, such as：The leakage of cable spacer, the possible abrasion of cable or short circuit, cable protection
The Problem of Failure of set, entire cost increase, complicated, failure rate increases；Although and the method that seeps water is without electrically heated safety
Problem, but its ground installation is complicated, by injecting hot water Paraffin Removal, tubing string is complicated, and operation is difficult, is easy to generate stratum
Injury effect, and final-period management expense increases.
For the present invention since the power of electric submersible pump is big, lifting rate is big, and the flow rate of liquid of tubing string is high, this can utilize this feature
It realizes that the mode of electromagnetic induction heat realizes the heating near wax deposition point, improves the efficiency of heating surface, change wax deposition point position
Wax deposition condition, reduce wax deposition phenomenon；And device is simplified, constructing operation is also simple, and failure rate significantly declines.
