Description
Technical field
The utility model belongs to oil field shaft mouth equipment, particularly relates to a kind of ultrasonic wave de-plugging oil well increasing and adopts the complete sets of equipment.
Background technology
In oilfield process, often because hindering crude oil, the obstruction of oil reservoir and pit shaft perforation flows out, reduce the permeability of crude oil, cause oil production to decline, affect middle and later periods oil well yield and oil recovery rate.For the de-plugging problem of pit shaft, have the roughly scheme of moulding at present.And to because of oil reservoir sand body loose cementation, have silt particle migration to stop up oil reservoir, and the problem that causes oil production to decline, also not installing can head it off.Therefore it is very necessary, provide a kind of de-plugging of well to increase adopting the complete sets of equipment.
Summary of the invention
Of the present utility modelly be intended to overcome the deficiencies in the prior art, provide a kind of ultrasonic wave de-plugging oil well to increase and adopted the complete sets of equipment.
Ultrasonic wave de-plugging oil well of the present utility model increases adopts the complete sets of equipment, to be formed by power distribution cabinet and magnetic orientator, described power distribution cabinet is connected with magnetic orientator and variable frequency type ultrasonic generator circuit respectively, variable frequency type ultrasonic generator is connected with the converter circuitry that is placed in oil well casing inwall, and magnetic orientator circuit has connected the locator that is positioned at sleeve pipe.
As further improvement of the utility model, described variable frequency type ultrasonic generator is by power supply, central processing unit, signal generator, power amplifier and PLL frequency feedback cell formation, and central processing unit, signal generator and power amplifier are connected successively, power amplifier is connected with transducer, transducer is connected to central processing unit through PLL frequency feedback unit, and central processing unit is connected with input-output equipment; Power supply is respectively central processing unit, signal generator, power amplifier, transducer and PLL frequency feedback unit power supply is provided.
As further improvement of the utility model, the front shroud periphery of transducer has been coated acoustical lens.
Ultrasonic wave de-plugging oil well of the present utility model increases adopts the complete sets of equipment, and its mechanism of action is as follows:
1, shock oscillation is peeled off effect: the ul-trasonic irradiation that directed boundling is launched is in oil reservoir, crude oil liquid, oil reservoir rock and solid particle just can vibrate with ultrasonic wave, due to the intrinsic frequency difference of each liquid, rock stratum, solid particle, so, the vibration acceleration producing separately and amplitude are also different, cause two kinds of phase material interface generation relative motions; Affinity between obstruction particle and rock stratum, profit particle is reduced, stop up thereby remove; Also make the former dirt being attached on rock stratum hole and venturi come off, with in direction of flow pit shaft, thereby dredging oil flow channel; Thereby make oil, water termination under ul-trasonic irradiation, form Water-In-Oil or oil-in-water emulsion liquid, thereby reduced viscosity, the recruitment mobility of liquid;
2, heat energy ionisation effect: under the effect of strong sound field, wax (dirt) just becomes superfine particle suspension in crude oil before not condensing, makes long-chain molecule produce cracking reaction, reduces its state of cure; Crude oil causes temperature rise to hyperacoustic absorption, and on liquid solid interface, acoustic energy will change into heat energy in a large number, and the localized hyperthermia that forms interface place even produces ionisation effect, thereby effectively prevents wax deposition (dirt);
3, cavitation effect: in sound field, the bubble in liquid progressively generates and expands, then vanishes suddenly, in this bubble collapse process rapidly, occurs HTHP in bubble, also forms local strong shock wave near liquid bubble.Therefore just can produce series of secondary effect, as chemical effect, sonoluminescence, peptizaiton and emulsification etc., strengthen oil reservoir penetrating power and accelerate oil stream flow velocity.
The effect of several aspects is comprehensively implemented on oil reservoir above, can make that obstruction within the scope of ul-trasonic irradiation is loose, dirt particle peel off from rock stratum come off, liquid viscosity reduces mobility and increases, near pressure reduction recycling pit shaft and the acoustic streaming effect of liquid, make oil layer blocking thing and dirt particle flow into smoothly pit shaft with liquid, thereby dredge oily discharge orifice road, washed rock stratum hole and venturi, reached and remove the object of stopping up.
Ultrasonic wave de-plugging oil well of the present utility model increases adopts the complete sets of equipment, reasonable in design, can effectively dredge pore constriction, remove oil layer blocking, have advantages of safe and reliable, cost is low, instant effect, efficiency is high, technique is simple, break-through ability is strong, treatment radius is large, to oil-water well, oil reservoir without injury, pollution-free, to pipe box not damaged, it is a kind of typical physics oil recovery technique.Can be widely used in the fields such as oil well increasing is adopted, water injection well unblocking and injection increasing.After using this device, the oily rate of increasing reaches more than 30%, and period of validity exceedes 90 days, and job success ratio can reach more than 95%.
