Description
Technical field
The utility model relates to oil extraction field, is a kind of liquid stream cavitation apparatus, system and method.
Background technology
Current oil field increases the main employing of oil two kinds of technology, and one is hydraulic fracturing technology, and two is ultrasonic cavitation technology.
Fracturing fracturing fluid is injected oil reservoir to manufacture a trunk crack, to reach the increasing oil tech changing oil stream fluidised form.The eighties in 20th century is the stage of outbalance in fracturing development history, after become oil gas gradually, the particularly important technical in Low Permeability Oil/gas exploration and development field.Fracturing increasing yield: when ground high-pressure pump group by high viscosity liquid to exceed in the discharge capacity Injection Well of formation absorption ability, shaft bottom produce pressure exceed the pressure of Around A Borehole geostatic stress and tensile strength of rock after, namely form crack in the earth formation.Along with the liquid of band proppant injects stratum, crack extends to form forward the sand packed fracture with certain length, width and height gradually.There is higher flow conductivity in this crack, changes oil and gas flow fluidised form.
But there is following shortcoming in fracturing: (1) complex process, operating cost is high.Fracturing is a rigorous system engineering, if not enough to reservoir geology situation understanding, that well and story selecting is improper, fracturing fluid is selected is improper, proppant is selected is improper, fracturing parameter design is unreasonable, scope of construction item is improper, discharge opeing improper measures all may cause pressing crack construction failure or reduce effect of increasing production after pressure, What is more may bring the modification scenario in oil gas field later stage and have a strong impact on.Stimulation technology is also a high investment, high risk technology, the operating cost of individual well generally hundreds thousand of between millions of unit, heavy duty service cost even ten million remaining yuan.(2) to oil well and formation contaminant serious.If it is improper that fracturing fluid is selected, cause stratum swelling clay mineral, emulsification of crude oil, mechanical admixture are brought into stratum, are incompatible to generate all possible formation such as precipitate and damage with formation water; For acid fracturing, liquid also can damage reservoir, and the corrosion inhibition difference of acid solution also can cause serious corrosion to construction equipment and tubing string.Fracturing work is a kind of operations involving high pressure, and working various chemical agent also can cause serious threat to the lives and properties of people and ecological environment.(3) very big to the destruction on oil well and stratum.If pressure break is improper, the serious consequence of oil well sudden water flooding and idle water filling can be caused, or contiguous aquifer or the oil reservoir top containing pneumatic jack are pressed off.In addition, discharge opeing improperly may strengthen to the extent of injury of reservoir, may cause proppant backflow, and then formation and oil well cause permanent destruction.(4) introducing in artificial trunk crack exacerbates the non-homogeneity of reservoir, and this brings adverse effect may to again the exploitation of oil-gas reservoir.
Ultrasonic oil production technology is one of tertiary oil recovery technology grown up nearly decades.Ultrasonic cavitation de-plugging increases oil tech and high-power ultrasonics block releasing technique.New type ultrasonic increases oil system primarily of compositions such as magnetic orientation system, special transmission cable, high-power ultrasonics signal of telecommunication emitter and ultrasonic wave electroacoustic transducers.The highpowerpulse electric oscillation signal that it utilizes ground on-vehicle large power supersonic wave transmitter to produce, pass through special transmission cable, Pulse Electric oscillator signal is transferred on the piezoelectric ceramic electro-acoustic conversion of oil reservoir, converts ultrasonic wave to through electroacoustic transducer, inject in oil bearing bed.By the nearly well oil reservoir of ultrasonic wave process for producing oil well, water injection well, the physical property of fluid in oil reservoir and fluidised form are changed, improves circulation condition and the permeability of near wellbore zone, shaft bottom, remove the blocking of producing well, water injection well, improve Discharge rate, crude output and water injection rate, to reach volume increase object.
But there is following shortcoming in ultrasonic cavitation: (1) ultrasonic cavitation can only be used for the de-plugging of near wellbore zone.Liquid medium produces cavitation bubble, and require that ultrasonic wave has certain intensity, the larger plugging removal effect of ultrasonic power is better.But hyperacoustic rate of decay is exceedingly fast, and there are some researches show, the sound intensity decays to 45% of sound source place at borehole wall place, and pore media geometrical model radius is that the sound intensity decay at 1 meter of is to 10% of borehole wall place.Therefore, the cavitation effect that ultrasonic wave produces can only act near wellbore zone, and maximum effect radius only 15 meters, therefore action effect is limited.(2) cavitation zone is in first valve state, the cavitation zone (or air pocket) formed at cavitation device periphery is limited in scope, along with the rising of hydrostatic (outside) pressure, in dark oil well, liquid stream cannot be interrupted form air pocket under high hydrostatic pressure.According to cavitation numerical requirements, for making the raw gap of liquid miscarriage, must with high speed force feed liquid, but be not can obtain this hypervelocity in all cases, especially in deep-well or lengthening pipeline; Under very high external hydrostatic water pressure power, such as in deep-well, ultrasonic wave is utilized to obtain cavitation effect.(3) be subject to processing time restriction, operation effectiveness is limited.Ultrasonic wave cumulative processing time is comparatively large on plugging removal effect impact, but the processing time more than 60 minutes after, plugging removal effect increase is not remarkable; Decay in the higher communication process of ultrasonic frequency larger, plugging removal effect is deteriorated.(4) complete sets of Techniques equipment is complicated, and operating cost is high, requires higher to operating environment.(5) oil well that gradient is greater than 45 degree is not suitable for.
