Sealing plug, can be close to the socket lock of underground ultrasonic wave producer and connect.
The construction processing process of this high-power ultrasonic oil formation treatment system of the utility model is as follows：
1st, by ground high-power ultrasonics control device operational procedure check inside and outside circuit, as voltage meets the requirements, then press
Order is started shooting.
2nd, winch is started, precalculated position will be arrived under underground ultrasonic wave producer with cable hoist.
3rd, carried out by the processing interval, supersonic generator depth of falling well and each process points processing time being pre-designed under
To upper segment processing operation, every section handles 1m, when processing time 1.0~1.5 is small/section.
4th, after having handled out of well take out underground ultrasonic wave producer, staticly settle 4~8 it is small when.
5th, by development plan requirement tripping in completion flow string.
6th, opening well and making production, enrolls oil well production dynamic and static data, with being contrasted before measure, distinguishes sonicated technique for oil formation
Construction effect.
This high-power ultrasonic oil formation treatment system provided by the utility model can realize do not have to human body and environment
Any influence, belongs to safe and environment-friendly, energy-saving outdoor equipment, meets safety and environmental protection requirement.
1st, the well blocked for the near wellbore zone formation contaminant as caused by mud dipping, kill-job, wax deposition and other reasons, is adopted
It is good with ultrasonic technology plugging removal effect；Good for reservoir physical property, core intersection is big, it is fuel-displaced can force difference and dynamic static data be not inconsistent
Well, is appropriately extended ultrasonic treatment time, can obtain more preferable treatment effect；Water injection well is after ultrasonication, it is necessary to note
Enter water water quality to be controlled by, otherwise influence whether the term of validity of ultrasonication.
2nd, it is closely related for low-permeability oilfield, the effect and oil reservoir self-condition of ultrasonication oil well.Reservoir permeability
Lower, viscosity of crude is bigger, and decay of the ultrasonic wave in oil reservoir is faster.Compared with high permeability zone, in identical construction technical data
Under, the effect of ultrasonication is poorer, and on the contrary then ultrasonication oil well effect is preferable.Therefore, for different reservoir conditions
Well, it should take different parameters.For in the process of development, the larger ultra-low permeability oil layer of pollution radius, utilizes ultrasound
The adaptability and methods for using them of ripple de-plugging, up for further research and it is perfect.
3rd, using the processed injection water of ultrasound, improve water quality, improve water injection well water absorption, prevent the secondary blocking of oil reservoir, be
Feasible.And ultrasonic wave improving injection control range is big, augmented injection effect is held time length, and technique is simple, and management is convenient.
4th, Changqing oilfields experimental study proves that the well that ultrasonic wave significantly declines oil yield after progress sand control, water blockoff is imitated
Fruit is notable.The stratum crossed to pressure break, improvement are handled still effective later.2500m or cementing causes are more than to well depth
Close, the very poor stratum effect of permeability is poor.The reason is that well is deeper, stratum diagenesis evolution is deeper, and formation cementation is fine and close, rupture pressure
Power is big, and further the potentiality of improvement permeability are small, in addition, depth of stratum increases, electroacoustic efficiency reduces.
5th, ultrasonication technique for oil formation has four compared with the conventional yield-increasing technique such as pressure break, acidifying, crowded liquid, steam soak
Difference.
1. pressure break, acidifying, to squeeze liquid be that pollutant is squeezed into earth formation deep, secondary pollution is easily formed, and ultrasonication
Pollutant can be discharged stratum.
2. the technique layered shapings such as pressure break, acidifying, crowded liquid are relatively difficult, often result in the high stratum of porosity and be processed
Open, and the low stratum of porosity can not receive effect, the development degree on stratum is affected, and be sometimes laminated High water cut
Open, cause waterflooded reservoir, and ultrasonication oil reservoir has flexible vertical resolution, depth error only has ± 10cm, can be exactly
Selected process layer position.
3. the techniques such as pressure break, acidifying, crowded liquid are bad to cementing quality, casing deformation, damaged well construction are difficult, or even nothing
Method is constructed, as long as and ultrasonic technology transducer can descend target oil reservoir normally to handle.
4. the techniques such as pressure break, acidifying, crowded liquid are employed, equipment is more, and construction personnel is more, and complex process is costly, and ultrasonic wave
Technology only needs a winch, three or four people, and technique is simple, and expense is low.In addition, ultrasonication technique for oil formation also has week of constructing
Phase is short, it is safe, without ground pollution, take the advantages that construction site is small, for oilfield stimulation, augmented injection provide one it is advanced, simple
Single feasible new method.It should be noted that although to have other well stimulations not compare excellent for ultrasonication formation stimulation technology
Point, but this method cannot substitute other methods.For example conventional pressure break can make the seam of relatively long distance, but the method for any vibration
All it is unable to handle, so, the concrete condition according to oil reservoir is had to, reasonably selection uses.
Ultrasonic technology is an emerging technology of oil field operation, is analyzed from technology and economic angle, it has most
Suitable operating condition, mainly improves reservoir permeability and reaches increasing yield and injection purpose, so being to belong to whole oil field operation city
One of field segments market, and it not is unalterable that this, which segments market, it can progressively expand with oil field development progress,
This is because with the implementation of other work measures, oil well geologic structure is also brought in development and change, other non-physical oil-extraction methods
Fluid pollution, necessarily cause the stratum such as the reduction of fluid mobility and penetrating power, pressure break modification measures also to have certain
Scope limits, and effect can be reduced constantly after multiple pressure break, and ultrasonic technology can play the effect of uniqueness, and will not be with
Specifically implement to bring influence to later operation effectiveness, thus this be one constantly extend segment market.
Exemplified as above is only for example, not forming to the scope of protection of the utility model to the utility model
Limitation, it is every to be belonged to the same or similar design of the utility model within protection scope of the present invention.
