According to the linear ultrasonic transducer array, the problems of yield reduction, injection reduction and the like caused by the aspects of low permeability, mud contamination, chemical agent blockage, operation contamination and the like of an oilfield can be effectively solved, and by an ultrasonic oil reservoir treatment technology, the yield increasing cost of an oilfield enterprise can be effectively controlled, the input-output ratio can be increased, and good economic and social benefits can be created.
Description
Technical field
The present invention relates to formation treatment device, more particularly to a kind of linear ultrasonic transducer array.
Background technology
In oil mining, stratum is oozed in middle and high hole certain production capacity in the early stage, but the prolongation with recovery time, yield
Decline very fast, in water injection well, general process does not have the well that water absorbing capacity or water absorbing capacity decline；Oil-gas-water layer is heavily polluted
Oil-water well, that is, because there is oil, the well polluting in the oil well that results in blockage of fouling, wax deposition or other operation process；Due to
Oil reservoir clay content is high, leads to the oil-water well that production capacity is substantially successively decreased progressively to be exploited with oil, the permeability reduction of nearly shaft bottom layer,
Oilbearing stratum tamper causes the blocking of oil well, and then reduces oil well output, leads to water content in crude oil to improve.
The basic thought of ultrasonic phased array technology comes from radar electromagnetic wave phased-array technique.Phased-array radar is by many
Radiating element lines up array composition, by controlling the amplitude of each unit and phase place in array antenna, the radiation side of adjustment electromagnetic wave
To synthesizing the radar beam flexibly quickly focusing on scanning in the range of certain space.Linear ultrasonic transducer array is by multiple
Independent piezoelectric chip composition array, excites each wafer cell by certain rule and sequential electricity consumption subsystem controls, then
Gradually by exciting each chip prespecified time delay, the ultrasound wave of all wafers transmitting forms an overall wavefront,
Shape and the direction of transmitting ultrasonic beam (wave surface) can be efficiently controlled, enable beam scanning, deflection and the focusing of ultrasound wave.
It is to determine that the shape of discontinuity, size and Orientation provide the ability bigger than single or multiple probe systems.
Content of the invention
The invention mainly solves the technical problem of providing a kind of linear ultrasonic transducer array, ultrasonic transduction can be passed through
The formation treatment of all-dimensional multi-angle is realized in the rotation of device frame, improves work efficiency.
For solving above-mentioned technical problem, one aspect of the present invention is: provides a kind of linear ultrasonic transducer
Array is it is characterised in that include: a kind of linear ultrasonic transducer array is it is characterised in that include: shell 1, roller 2, ultrasonic
Transducer frame 3, ultrasonic probe array 4, support column 5 and fix bar 6；
Described shell is barreled shell, upper-lower seal；Described support column two ends are fixed on inside the top and bottom of described shell；Described
Fix bar one end is passed through to fix on the support columns, and the other end is fixed on described ultrasonic transducer frame inwall；Described ultrasonic transducer
Frame is circular shell structure, equidistantly distributed sector ultrasonic probe array on housing.
Preferably, described ultrasonic probe array include prolonging described ultrasonic transducer frame outer wall linear distributing from top to bottom
Piezoelectric chip and ultrasonic transducer group.
It is different from the situation of prior art, the invention has the beneficial effects as follows: ultrasound wave formation treatment technological adaptability is strong, wind
Danger is little, harmless to oil reservoir, the oil field particularly to the tail period stage, and near wellbore zone pollution becomes common problem, adopts
Use Ultrasonic oil production technology, can effectively solve oil field because of the aspect such as hypotonic, mud contamination, chemical agent blocking, operation pollution
The underproduction that causes, the problems such as reduce, ultrasound wave formation treatment technology can make oilfield enterprise effectively control volume increase cost, improves
Input-output ratio, the good economic benefit gone and social benefit.
Brief description
Fig. 1 is the schematic diagram of embodiment of the present invention linear ultrasonic transducer array.
Fig. 2 is linear ultrasonic transducer array cross-sectional view of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
A kind of linear ultrasonic transducer array providing referring to Fig. 1 is it is characterised in that include: shell 1, roller 2, ultrasonic
Transducer frame 3, ultrasonic bullet array 4, fix bar 6 and support column 5；
Described shell 1 is cylinder-like shell, upper-lower seal；Described support column 5 two ends are fixed in the upper and lower surface of described shell 1
Side；Described fix bar 6 one end is connected on support column 5 by rotational structure, and the other end is fixed in described ultrasonic transducer frame 3
Wall；Described ultrasonic transducer frame 3 is circular shell structure, and enclosure interior installs ultrasonic transducer 4；Described ultrasonic transducer frame
3 outer walls prolong circumference and arrange one chute, and between described shell 1 and ultrasonic transducer frame 3, setting assembly pulley 2 is so that ultrasonic transducer
Frame can rotate freely in inside the shell；Described ultrasonic transducer frame is suspended on inside the shell by described chute by described assembly pulley 1.
In specific operating process, the ultrasonic probe chip combination of ultrasonic phase array, pressed certain by multiple piezoelectric chips
Rule is arranged evenly, then gradually by exciting each chip prespecified time delay, the ultrasonic waveform of all wafers transmitting
Become an overall wavefront, shape and the direction of transmitting ultrasonic beam (wave surface) can be efficiently controlled, enable the ripple of ultrasound wave
Beam scanning, deflection and focusing, the electrical power of input is converted into mechanical output by ultrasonic transducer group, according to scanning direction and scanning
Result completes the process work of oil reservoir.
By the way, the linear ultrasonic transducer array of the embodiment of the present invention can effectively solve oil field because low
Ooze, the underproduction that the blocking of mud contamination, chemical agent, the aspect such as operation pollution cause, the problems such as reduce, ultrasound wave formation treatment technology
Oilfield enterprise can be made effectively to control volume increase cost, improve input-output ratio, the good economic benefit gone and social benefit.
