Abstract
The invention discloses the application of the ultrasonic wave of crude oil to oil exploitation, wherein the ultrasonic wave can be used to change the physical properties and the flow state of the fluid in the oil layer. An ultrasonic power supply is used for making a vibrating rod which connects ultrasonic transducers together through a cable go deep into the oil layer to carry out ultrasonic treatment to the fluid in the oil layer. Because the ultrasonic wave is used for treating the oil layer, the production can be increased obviously. In addition, the ultrasonic equipment is relatively low in investment cost, simple in construction process, low in cost and high in benefit. Moreover, the ultrasonic wave can be used together with other production increasing methods to complement the advantages and plays an important role in increasing the production of the oil field in the later stage.
Description
Technical field
The present invention relates to hyperacoustic application, refer more particularly to the application of ultrasonic wave in the oil mining process.
Background technology
In the oil mining process, usually can hinder crude oil and flow in the pit shaft because a variety of causes forms some obstructions in oil well, reduce the permeability of crude oil, affect output and the oil recovery rate of middle and later periods oil well.
Summary of the invention
Technical problem to be solved by this invention is: a kind of application of ultrasonic wave in the oil exploitation process that makes the physical property of fluid in the oil reservoir and fluidised form change, improve crude oil is provided.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: the application of ultrasonic wave in the oil exploitation process, the steps include: that ultrasonic power gos deep into ultrasonic transducer in the oil reservoir with the vibrating head that links to each other with ultrasonic transducer by cable, the fluid in the oil reservoir is carried out ultrasonic wave process.
The power of described ultrasonic power is more than 2KW.
Described cable by sheath and be wrapped in the sheath a pair of power line and at least steel cable consist of.
The invention has the beneficial effects as follows: the present invention adopts ultrasonic wave that oil reservoir is processed, so that the physical property of the fluid in the oil reservoir and fluidised form change, improve circulation condition and the permeability of shaft bottom, nearly well oil reservoir, remove obstruction, antiscaling, descaling, wax control, improve oil production, reduce the viscosity of crude oil.In addition, when powerful ultrasonic wave enters in the oil reservoir, little variation when large in the time of will occuring along with hyperacoustic mechanism of the capillary diameter in the oil reservoir.When capillary diameter changed, its surface tension, capillary force also changed thereupon.When capillary radius becomes large, surface tension square is doubly dwindled with radius, capillary force cube doubly dwindles with radius, this is broken with regard to the equilibrium relation that makes original capillary force and gravity, be strapped in the residual oil in the capillary tube, because the equilibrium of forces relation is broken, and flows in the well under gravity and hyperacoustic effect of vibration.In addition, under the effect of high-power ultrasonics, oil reservoir also can split, and forms the crack, thereby improves the permeability of crude oil.
Adopt ultrasonic wave that oil reservoir is processed, effect of increasing production is comparatively obvious; And the investment cost of ultrasonic equipment is relatively low, and construction technology is simple, and cost is low, high efficiency; And can be combined with other method for increasings, have complementary advantages; And, important effect is played in the later stage volume increase in oil field.
The specific embodiment
Describe the application of ultrasonic wave of the present invention in the oil exploitation process in detail below by two embodiment:
Embodiment one:
The application of ultrasonic wave of the present invention in the oil exploitation process, the steps include: the ultrasonic power of 2KW the fluid in the oil reservoir to be carried out ultrasonic wave process by with the cable that steel cable consists of ultrasonic transducer being goed deep in the oil reservoir with the vibrating head that links to each other with ultrasonic transducer with a pair of power line in being wrapped in sheath by sheath.
Embodiment two:
The application of ultrasonic wave of the present invention in the oil exploitation process, the steps include: the ultrasonic power of 3KW the fluid in the oil reservoir to be carried out ultrasonic wave process by with the cable that a pair of wire rope consists of ultrasonic transducer being goed deep in the oil reservoir with the vibrating head that links to each other with ultrasonic transducer with a pair of power line in being wrapped in sheath by sheath.
