When the plugging device is assembled, the plugging device is installed at the bottom of the pulse generator through the central hole 16 in a threaded mode, and therefore the mechanical vibration plugging removal and injection increasing oil increasing device is assembled.
The pulse generator is composed of an upper shell 4, a lower shell 5, a plugging disc 6 and a vibrating disc 7; the top of the lower shell 5 is provided with an upper shell 4 in a threaded manner, and a screw rotor 9 is arranged in the upper shell 4 through a screw bushing 8; a vibrating disk 7 is movably arranged in the lower shell 5 through an assembling plate 10 and a sliding sleeve 11, and the vibrating disk 7 is fixedly connected with a screw rotor 9; the vibration plate 7 is connected in sliding contact with the sliding sleeve 11 and the fitting plate 10.

When the mechanical vibration blockage removing and injection increasing oil increasing device works, firstly, the mechanical vibration blockage removing and injection increasing oil increasing device is lowered to an oil layer 3 to be blocked in an oil well through the operation vehicle 1 and the continuous oil pipe 2, then, a high-pressure pump on the operation vehicle 1 is started, and under the action of the high-pressure pump, liquid in the operation vehicle 1 enters the mechanical vibration device through the continuous oil pipe 2.
The high-pressure liquid entering the mechanical vibration deblocking and injection increasing oil increasing device firstly impacts the screw rotor 9 to rotate, the rotor 9 rotates and drives the vibration disc 7 to rotate, the high-pressure liquid impacting the rotation of the screw rotor 9 enters the vibration cavity 12 in the vibration disc 7 through the bypass holes 13 on the vibration disc 7 and is collected, and the vibration disc 7 continuously rotates and periodically opens and closes between the liquid flow hole 14 and the overflowing hole 15 in the rotating process, so that the high-pressure liquid descending through the liquid flow hole 14 and the overflowing hole 15 forms pulse liquid flow and continuously descends into the central hole 16 of the blocking disc 6, and the high-pressure liquid entering the central hole 16 of the blocking disc 6 is acted on the mounting handle 18 of the fan-shaped piece 17 to press the fan-shaped piece 17 to radially extend out and be attached to a well wall, so that the well hole is blocked. In the process that the fan-shaped sheets 17 radially extend out, as the high-pressure liquid in the central hole 16 simultaneously acts on the 4 mounting handles 18, the radial pressure on the 4 fan-shaped sheets 17 is equal; the 4 segments 17 cooperate to radially expand the elastomeric rubber ring 19 to conform closely to the borehole wall. Wherein, when the installation handle 18 drives the fan-shaped piece 17 to extend out radially, the installation handle 18 gradually releases the blocking state of the impact hole 20, and when the high-pressure liquid presses the fan-shaped piece 17 to extend out radially, part of the liquid enters the well hole below the blocking disc 6 through the impact hole 20 in a pulse type and is collected; when the blocking state of the installation handle 18 to the impact hole 20 is completely released, the positioning hole 37 on the installation handle 18 is matched with the insertion rod 34 of the positioning mechanism, and the end of the insertion rod 34 is inserted into the positioning hole 37 under the pressure action of the counterweight cylinder 31, so that the installation handle 18 can be prevented from retracting, and the tight attaching state of the elastic rubber ring 19 and the well wall can be ensured.
After a certain amount of liquid is collected in the well hole below the plugging disc 6; the fluid radially enters the reservoir through the formation pores of the reservoir 3 and propagates within the formation pores; in the process that liquid spreads in the pores of the rock stratum, along with the continuous entering of the pulse liquid flow formed by the impact holes 20, the liquid collected in the well hole below the plugging disc 6 forms wave-type surging; because the liquid (liquid) has the characteristic of rigidity and incompressibility, the liquid (liquid) can be transmitted in the pores of the rock stratum, and when high-energy pulse hydraulic waves (surging waves) of the liquid act on an oil layer, the liquid (oil liquid) and solid particles in the rock stratum vibrate together; while the liquid and solid particles are vibrated together; because the natural frequencies of petroleum liquid, rock stratum and solid particles are different, the vibration acceleration and the vibration amplitude generated by the natural frequencies are different, so that the interfaces of two or more phase substances generate relative (collision) motion, the particles of the blocking object can loosen due to the relative motion, dirt, oil stain and colloid on the pore throat of the rock stratum can be rapidly peeled off and diffused in mixed liquid of oil liquid and liquid, and enter a borehole along with the circulating flow of the mixed liquid, and the purposes of dredging an oil flow channel, recovering or improving the porosity of an oil layer in a near-well zone, finally improving the flow conductivity of the oil layer and improving the yield of an oil well are achieved.
The pressure of the mixed liquid in the well hole continuously rises along with the continuous entering of the liquid into the oil storage layer 3 in the circulating flowing process, when the pressure continuously rises to a certain value, the mixed liquid in the well hole pushes the one-way valve 21 on the plugging disc 6 to open, and then the mixed liquid enters the well hole above the plugging disc 6, so that liquid flow circulation is formed until the plugging removal and injection increasing oil increasing operation at the position of the oil layer to be plugged is completed. The mechanical vibration blockage relieving and oil increasing device can also perform segmented blockage relieving and oil increasing operation on the blocked oil layer, the blocked oil layer is divided into an upper section, a middle section and a lower section during the segmented blockage relieving and oil increasing operation, firstly, when the blockage relieving and oil increasing operation is performed on the lowest blocked oil layer, the pressurizing is stopped after the blockage relieving, oil increasing and oil increasing operation is completed, the fan-shaped sheet 17 retracts radially under the action of the elastic rubber ring 19 to reset, and the blocking state of the well hole by the blocking disc 6 is relieved; at the moment, the mixed liquid in the well above the plugging disc 6 falls back to the well below the plugging disc 6 through the gap between the plugging disc 6 and the well, and is integrated with the mixed liquid below the plugging disc 6, at the moment, the mechanical vibration plugging removal and injection increase oil increasing device is lifted for a certain distance, the steps are repeated, the plugging removal and injection increase oil increasing operation can be carried out on the middle-section plugged oil layer, and the process is circulated until the plugging removal and injection increase oil increasing operation of the whole plugged oil layer is completed. The plugging device for the mechanical vibration plugging removal and injection increasing oil increasing device is characterized in that a vibration shock wave formed by a pulse generator presses a pressing disc to radially extend out, so that plugging of a well hole is realized, and the plugging state of the plugging device is maintained through a positioning mechanism; after the operation is finished, the plugging device is unsealed through the matching of the positioning mechanism and the elastic rubber ring 19, so that the problems of complex structure, high manufacturing cost, poor plugging effect and inconvenience in unsealing of the existing plugging device are solved, and the plugging device has the characteristics of simple structure, strong reliability and good applicability; is particularly suitable for mechanical vibration blockage removal and oil increase operation.
