The utility model has adopted two-stage ultrasonator, improves frequency of sound wave, thoroughly destroys the crystalline solid of paraffin, increases wax-proof viscosity reducing effect, and adopts eddy-current technique to improve the mobility of crude oil.Operating principle of the present utility model is summarized as follows:
One, twin-stage jet ultrasonator:
Crude oil is first by the wedge shape through hole of the jet head in one-level ultrasonator, flow velocity improves rapidly (approximately 50 times), form jet, in crude oil, the crystalline solid of wax (or micel) has experienced a crushing failure at high speed distortion fragmentation and broken two processes of Rapid Expansion distortion in jet occurs, the crystallization tissue of wax is subject to very big destruction, then be superfine micel or molecule and exist, thereby produced wax-proof viscosity reducing effect.Crude oil forms jet through one-level ultrasonator shrapnel device, under the powerful alternating force effect of jet, can produce the vibration wave of 4000-25000HZ.This medium-high frequency vibration wave directly acts in crude oil medium, and spreads therein.Jet enters the wedge shape through hole in secondary ultrasonator, the very fast lifting of flow velocity (approximately 120 times), stroke overshot stream, the part wax crystal (or micel) in crude oil is fully pushed or is broken when through one-level ejector, will obtain therein sufficient attrition crushing; Originally superfine micel also will obtain secondary and destroy, and be the state of thinner micel or molecule and will exist, thereby produce the effect of secondary wax-proof viscosity reducing.The secondary jet of crude oil stroke is through vibration shrapnel device, and the frequency of sound wave of jet generation is promoted to 8000-50000HZ, and this acoustic wave energy has obtained the lifting of matter through secondary oscillator.Meanwhile, sonic tube compared to before similar products increased cavity length, sonication can be completed more fully in cavity.
Through test and application, two ejectors are set in same cavity, after a jet of second ejector reception of jet direction, can destroy to larger efficiency the crystallization tissue of wax, thereby produce the effect of secondary wax-proof viscosity reducing, improve the utilization rate of jet cavity.Following form is the experimental data form of the ultrasonic wax control generator of single-stage, as the reference data of sending out to twin-stage wax control generator ultrasonic:
According to the research of the C.M.Kagieib of former Soviet Union professor and houston, u.s.a SPOR company, vibration wave, at crude oil Propagation, mainly can produce the effect of two aspects:
The one, mechanical oscillation effect.Vibration wave energy forces material molecule or micel in crude oil medium to do strong mechanical oscillation.This powerful Unidirectional acting force consistent with Acoustic Wave Propagation direction, both long-chain molecule key that can tear fracture crude oil, reduce crude oil motion viscosity, make viscosity reach 1500 mPaS-4000mPaS, there is good mobility, lattice structure that again can tear fracture wax crystal, prevents condensing and separating out of wax.
The 2nd, fuel factor.When vibration wave passes fluid media (medium), the certain energy of Absorption of Medium, can cause local heating.Frequency is higher, and fuel factor is more remarkable.Use this wax-proof viscosity-reducing oil-increasing device, can make the crude oil medium of flowing through heat up approximately 5 ~ 8 ℃, reduce wax condensation point 20-35 ℃, further strengthened the incremental effect of wax-proof viscosity reducing.
Two, cavitation cabin effect:
Crude oil is due to the resistance of jet wedge mouth, impel crude oil in above part self-assembling formation one vacuum section of wedge mouth outlet, certain growth that carry out in this cavitation chamber, strengthening jet, the cavitation of sonic oscillation forms, crude oil in cavitation cabin owing to being subject to jet, the effect of supersonic oscillations, constantly produce cavitation bubble, under vacuum environment, bubble is vanished rapidly, in bubble-break moment, bubble internal pressure can reach several thousand Pa, temperature can reach several thousand degrees Celsius, the acceleration producing is several thousand times of its gravity, accelerated the pulverizing to long-chain wax crystallization in crude oil and crude oil strand, the fuel factor that the broken acting of cavitation produces, crude oil medium temperature is raise, in cavitation cabin, further strengthened wax-proof viscosity reducing mobilization.
Three, eddy current water conservancy diversion ejector:
Crude oil enters the diversion section of eddy current water conservancy diversion ejector through pulverizing and cavitation by cavitation cabin, by heavy in section rectilinear motion station guide stroke small bore eddy current water conservancy diversion state, greatly improved the flow velocity of crude oil, and organized pulverizing and cavitation the gathering again of wax micel.
Crude oil is again through one-way guide flow valve, and its Main Function is further to dwindle overflow section, makes ring-type vortex ejiction opening of crude oil stroke; The negative pressure space that keeps cavitation cabin; Another effect is to prevent that the crude oil that oil pumper down stroke causes from refluxing.
The ring-type eddy current crude oil ejecting through one-way guide flow valve amplifies through the jet segment negative pressure of vortex water conservancy diversion ejector again, and pressure reduction further expands, and flow velocity further promotes, thereby has greatly improved the mobility of crude oil, has improved pump efficiency.
Main feature of the present utility model is:
1. utilize first dual-jet parts to carry out jet wax control to crude oil, thoroughly destroyed the crystalline solid of paraffin, increased wax-proof viscosity reducing effect, efficiently solve blockage problem; Can not adapt to especially paraffin content at more than 25% well recovery;
2. safety and environmental protection, without any side effects;
3. need not any extrinsic motive or the energy;
4. the scope of application is wide, has both been applicable to dissimilar producing well, is applicable to again the oil well of different paraffin contents and water content;
5. simple installation, reliable, and under high temperature, high pressure, high corrosive environment, life of product is long.
