The rare earth permanent magnetic wax prevention device is characterized in that the inner pipe is internally provided with 11 sections of special-shaped magnetic steels, the lower end of the pipy component is provided with a lower joint, and the upper end of the pipy component is provided with a connecting joint; the special-shaped magnetic steels are formed by the way that two N poles and two S poles are alternately arranged. The utility model is mainly used for a wax deposition oil well or an oil pipeline of the wax deposition oil well, prolongs the periods of wax deposition and scaling, and reduces the time to clean wax and scale or prolongs the wax deposition oil period of the oil pipeline.
Description
Technical field
The utility model relates to the auxiliary equipment in the oil extraction equipment, is specifically related to a kind of wax control device.
Background technology
Oil well is in recovery process, effusion along with gas in the reduction of crude oil temperature and pressure and the crude oil, the paraffin that is dissolved in the crude oil can be separated out in crystallization, can stop up oil-producing formation after wax crystal is separated out and grow up to assemble to be deposited on the tubing wall, has a strong impact on oil well production.Prior art adopts mechanical paraffin removal, heating power wax removal, paraffin removing with chemical method and microorganism dewaxing method to prevent paraffin deposit more, but dewaxing method labour intensity is big, required expense height, require the wax removal number of times frequent, the most employing filled the rare earth magnetic steel particle and realized on the equipment in the interior pipe of wax control device and the gap between the shell, there is the leakage field phenomenon, influences the operate as normal of measurement and control instrument instrument.
Summary of the invention
The purpose of this utility model provides a kind of rare earth permanent magnet wax control device, is mainly used on the oil pipeline of waxing in production well or waxing in production well, prolongs the wax deposition fouling cycle, reaches to reduce wax removal snaking number of times or prolong the petroleum pipeline wax deposition cycle.
The technical scheme that realizes the utility model purpose is a kind of rare earth permanent magnet wax control device, be made of a tubular element, pipe and shell in tubular element comprises is characterized in that being provided with the special-shaped magnet steel of 11 joints in interior pipe, lower end at tubular element is provided with lower contact, is provided with connector in the upper end of tubular element; Described special-shaped magnet steel is alternately rearranged by 2 the N utmost points and the S utmost point.
The utility model has the advantages that
1, this product adopts novel rare earth permanent-magnetic material, the magnetic energy product height, and residual magnetic flux density is big, hot operation temperature height, long service life, anti-wax deposition is effective.
2, through the special-shaped magnet steel of specially treated, magnetic circuit closed nothing leaks, and magnetic leakage free is noiseless to the measurement and control instrument instrument, helps the operate as normal of flow circuit.
3, this wax control device compact conformation, volume is little, and actual internal area is big, high efficiency.
Description of drawings
Fig. 1 is an oil country tubular good wax control device scheme of installation.
Fig. 2 is a structural representation of the present utility model.

TBG
When being applied on the oil pipeline of waxing in production well, as shown in Figure 1, wax control device is installed in 150-200 rice before the pipeline wax deposition section, adorns one every the 500-600 meter ampere, and until the downstream petroleum transferring station, the effective wax control distance of wax control device is a 700-800 rice.
Important technological parameters is as follows:
Magnetic field intensity: 4500～7000GS
Hot operation temperature: 150 ℃
Instrument length overall :～960mm
Instrument external diameter: Φ 106mm
Interior latus rectum: Φ 55mm
Connect button-type:
TB
In a preferred embodiment of the present utility model, in crude oil was analysed 32～38 ℃ of serious temperature ranges of wax, the wax crystal inhibiting rate was 53.88%, and general chemical anti-wax technique only can reach 16%, and the wax precipitation point of magnetization sample descends 1～4 ℃.Viscosity of crude ground reduced rate is 47.3～52.2%, and the diameter of scale particles is reduced to 0.14um from 3.39um.Pump detection period extends to 525 days, and the pump detection period of paraffin control with inhibitor technology only is 138 days.
