Abstract
The utility model relates to an underwell variable frequency sound wave vibrating instrument, which is composed of a connector of an underwell cable and a device 1, a well temperature measurer 2, a magnetic position finder 3, a frequency tester 4, a connector 5, a testing sensor 6, a vibrating motor fixer 7, a direct current frequency variable motor 8, a pressure casing 9, a vibrating motor fixation pressure ring 10, an eccentric center vibrating drum 11, a vibrating motor lower fixation plug 12 and a ground control part 13. Because the utility model adopts the direct current frequency variable motor to drive the eccentric center vibrating drum to rotate under the control of the ground control meter, and then the vibration wave which is vertical with a motor shaft is generated, the vibrational force destroys the oil and water surface in the stratum and the tension of two kinds of liquid surfaces with different character, and a microcrack is formed at the area where is near the well by dredging a blocked pore space in the stratum. The oil which can not flow is disengaged from the binding of the stratum and flows, and the oil is extracted out along the injected water, as a result the containing water of the oil extraction well is degraded, and the oil recovery rate is enhanced.
Description
Technical field:
The utility model relates to the downhole tool that uses on a kind of field produces, particularly a kind of down-hole frequency conversion acoustic vibration instrument.
Background technology:
In DP technology with water drive oil, owing to influenced by the anisotropism of off-take target and well-completing process, after a period of time, under the high pressure effect of injecting water, often make a certain position of the target zone that injects water cause spike to advance by leaps and bounds at water flooding recovery, and passage in the formation layer, make injection water directly enter the oil recovery producing well, the moisture rapid rising of well that consequently is benefited greatly reduces waterflooding effect, increase cost for oil production, caused the waterflood problem.
Technical scheme
The purpose of this utility model is to provide a kind of down-hole frequency conversion acoustic vibration instrument, and it makes the crude oil in the stratum mix with injection water by the vibrations stratum, has improved waterflooding effect greatly, reduces waterflood.
The purpose of this utility model is to realize like this, by downhole cable and instrument connector (1), temperature survey instrument (2), magnetic position indicator (3), Frequency tester (4), connector (5), testing sensor (6), vibrating motor fixator (7), direct current variable frequency motor (8), bearing shell (9), vibrating motor fixed pressure ring (10), eccentric vibrating wheels (11), fixing plug (12) under the vibrating motor, ground control section (13) is formed, ground control section (13) is connected with instrument connector (1) by cable, connector (1) successively with temperature survey instrument (2), magnetic position indicator (3), Frequency tester (4), connector (5), bearing shell (9), fixedly plug (12) connection under the vibrating motor, connect at bearing shell (9) internal upper part and to be connected to testing sensor (6) successively, vibrating motor fixator (7), direct current variable frequency motor (8), bottom are connected to vibrating motor fixed pressure ring (10), eccentric vibrating wheels (11).
Connect in the lower going-into-well by logging cable during work, the degree of depth of the target zone that provides according to the user, record the well inner sleeve box cupling degree of depth with the magnetic position indicator, to guarantee making frequency conversion acoustic vibration instrument aim at target zone, carry out vibration service in the target zone repeated multiple times, measure the variations in temperature of operation level in real time by the temperature survey instrument, to observe target zone fluid situation.Control the speed that the DC voltage of going into the well changes motor by direct current variable frequency motor by the ground controller, the down-hole variable-frequency motor drive the rotation of eccentric vibrating wheels produce with motor shaft to vertical 20HZ～150HZ vibration wave, vibration wave forms horizontal transmission in the down-hole, this vibration is propagated with liquid in the well and formation skeleton and is done communications media generation vibration, this vibration force has been destroyed oil-water interface and the two kinds of liquid surface tensions of different nature in the stratum, crude oil in the stratum is mixed with injection water, increased the effect of water drive oil greatly.
The utility model is owing to adopted to connect at the bearing shell internal upper part and be connected to testing sensor successively, the vibrating motor fixator, direct current variable frequency motor, the bottom is connected to the vibrating motor fixed pressure ring, eccentric vibrating wheels, by direct current variable frequency motor by the control of ground controller drive down eccentric vibrating wheels rotation produce with motor shaft to vertical vibration wave, this vibration force has been destroyed oil-water interface and the two kinds of liquid surface tensions of different nature in the stratum, and can dredge blocked formation pore, form microcrack in nearly well area, make the oil that can not flow break away from the constraint on stratum and flow, go out with injecting hydromining, thereby reduce the moisture of producing well, improve recovery ratio.The utility model is simple in structure, and easy construction is reasonable in design, is well suited for field popularization application.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further specified.
Embodiment:
As shown in the figure, the utility model is by fixedly plug 12, ground control section 13 are formed under downhole cable and instrument connector 1, temperature survey instrument 2, magnetic position indicator 3, Frequency tester 4, connector 5, testing sensor 6, vibrating motor fixator 7, direct current variable frequency motor 8, bearing shell 9, vibrating motor fixed pressure ring 10, eccentric vibrating wheels 11, the vibrating motor, down-hole frequency conversion acoustic vibration instrument external diameter Φ 102～127mm, 175 ℃ of heatproofs, withstand voltage 80Mpa, operating voltage DC10～110V, operating current 1～8A, frequency 20～150HZ.Change the speed of motor by the DC voltage of going into the well by ground control section (13) control by direct current variable frequency motor (8), this frequency can be adjustable continuously from 20HZ～150HZ, because be a kind of continuous low-frequency sound wave, therefore its dissemination radius can reach more than the 100M, and can not cause secondary pollution to oil reservoir, its operating cost will be significantly less than other and increase oily measure.The ground control section comprises: dc voltage regulator power supply, underground work frequency show, well depth indication down.
It can also do the down-hole vibroseis of the low-frequency sound generator and the crosshole seismic imaging measurement of underground low-frequency acoustic logging instrument.
