Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail below by referring to the accompanying drawings and examples.
The embodiment of the application discloses a carbon dioxide oil displacement and sealing tool, which is connected with a pipeline through a female port at the upper part through threads. As shown in fig. 1, the carbon dioxide oil displacement and sealing tool comprises a columnar shell 1 with a sealed hollow lower part in the middle, an inner cylinder 13 is arranged in the shell 1, four shell gaps 4 are formed in the side surface of the shell 1 every ninety degrees, grooves which are the same in number with the shell gaps 4 and have the same geometric center in the same height are formed in the side surface of the inner cylinder 13, a microbubble generation system can be communicated with the shell gaps 4 when the inner cylinder 13 rotates to the corresponding position, a microbubble generation system is arranged in the grooves, the thickness of the grooves is the same as that of the microbubble generation system, the microbubble generation system is attached to the inner wall of the shell 1, and inner cylinder gaps 12 are formed in the bottoms of the grooves. The inner cylinder gap 12 communicates the microbubble generation system with the inner space of the inner cylinder 13, and the size of the inner cylinder gap 12 is smaller than the size of the groove. The bottom of the inner cylinder 13 is connected with a rotary flange 17, and the rotary flange 17 is connected with a motor control device through a coupler 7.
As shown in fig. 1-3, a top sealing cover 11 is arranged at the upper port of the inner cylinder 13, so that the inner cylinder 13 is separated from the upper gas, and carbon dioxide can only enter the inner cylinder 13 through the female port. The top sealing cover 11 is provided with a clamp spring groove 20, and a fixed clamp spring 2 is arranged in the clamp spring groove 20 to limit and fix the shell 1 and the inner barrel 13. The sealing ring grooves 30 are arranged at the two ends of the inner cylinder 13 and on the top sealing cover 11, and the sealing rings 3 are arranged in the sealing ring grooves 30, so that the purpose of preventing large-bubble carbon dioxide from entering the shell 1 through the inner cylinder gap 12 and then entering the oil pipe through the shell gap 4 is to ensure that the pressure in the inner cylinder 13 is gradually increased during carbon dioxide filling.
As shown in fig. 4, 5 and 7, the microbubble generation system includes a filter screen 6 attached to the inner cylinder gap 12 and a microbubble generation sheet 5 attached to the inner wall of the housing 1. The microbubble generating pieces 5 and the filter screen 6 are the same as the grooves in size, and the inner cylinder gap 12 is smaller than the grooves, so that the microbubble generating system is fixed in the grooves. Wherein the microbubble generating sheet 5 is porous ceramic. When carbon dioxide enters the inner cylinder 13, impurities and particles are carried, and damage to the inner cylinder 13 may occur. When injecting carbon dioxide with large bubbles, impurities and particles in the carbon dioxide are filtered out through the filter screen 6 attached to the inner cylinder gap 12, and then enter the microbubble generating sheet 5 to convert the carbon dioxide with large bubbles into tiny bubbles. After the carbon dioxide is subjected to micro-bubble formation and impurity removal, the carbon dioxide with micro-bubbles enters the shell 1 through the inner cylinder gap 12 and leaves the carbon dioxide flooding and sealing tool through the shell gap 4. The seal ring 3 prevents large bubbles of carbon dioxide from entering the housing 1 through the inner cylinder gap 12, but allows small bubbles of carbon dioxide to enter the housing 1 through the inner cylinder gap 12.
As shown in fig. 2, the rotary flange 17 is provided with a sensor mounting groove 21, and a pressure sensor 14 is provided in the sensor mounting groove 21, and the pressure sensor 14 is connected to the motor control device. As shown in fig. 6, the upper end of the coupler 7 is provided with a coupler big end hole position 22, and the lower end of the rotary flange 17 is fixedly arranged in the coupler big end hole position 22; the lower end of the coupler 7 is provided with a coupler small end hole site 23, and a motor rotating shaft of the motor 15 is fixedly arranged in the coupler small end hole site 23. With the input of carbon dioxide, the pressure in the inner cylinder 13 is gradually increased, when the pressure reaches a threshold value, the rotary flange 17 is pressed, the rotary flange 17 transmits the pressure to the pressure sensor 14, and the pressure sensor 14 converts the pressure variation into an electric signal. The pressure sensor 14 is connected with the motor 15 through an electric wire, and an electric signal generated by the pressure sensor 14 is transmitted to the motor control device through the electric wire so as to achieve the effect of starting the motor 15.
The motor control device comprises a motor shell 16, a motor top cover 8 is arranged above the motor shell 16, a motor 15 connected with a coupler 7 and a pressure sensor 14 is arranged in the motor shell 16, and a control nipple 9 and a battery nipple 10 are sequentially arranged below the motor 15. The battery nipple 10 can store redundant electric quantity, when the content of carbon dioxide is reduced, and when the pressure in the inner cylinder 13 is reduced, the pressure does not reach the threshold value of the pressure sensor 14, the pressure sensor 14 stops outputting the electric signal to the control nipple 9, and at the moment, the control nipple 9 drives the motor 15 to return to the initial state. In order to prolong the service lives of the motor 15 and the battery nipple 10 and prevent the motor from being worn out too fast, the motor top cover 8 and the motor shell 16 both play a role in protecting the motor 15, and the shell 1 also completely wraps and protects the motor control device.
As shown in fig. 8, which is a schematic block diagram of PCB control logic in the control nipple 9, the broken line connection indicates that power is directly supplied by the battery nipple 10, and the solid line connection indicates that electric signals are transmitted between the modules in the control nipple 9. The microcontroller, the ADC sampling circuit, the brushless DC motor driver and the pressure sensor 14 outside the control nipple 9 in the control nipple 9 can be powered by the battery nipple 10. When the pressure sensor 14 starts to work, the pressure is gradually increased, the voltage signal transmitted to the ADC sampling circuit is also gradually increased, the voltage signal is converted into a digital signal through AD conversion, after being processed by the microcontroller, whether the voltage signal exceeds a preset value or not is judged, and if the voltage signal exceeds the preset value, the microcontroller sends a control signal to the DC motor driver, so that the motor 15 is driven to rotate. The motor encoder data is read by the microcontroller, so that the position and speed information of the motor rotor can be obtained, the phase current data of the motor is sampled and collected by the ADC, and the cascade PID control algorithm is used in combination with the current data, so that the rotating position can be accurately controlled. When the operation is stopped, the pressure is reduced due to gradual reduction of carbon dioxide in the cylinder, the voltage signal of the pressure sensor 14 is reduced, and when the AD conversion value of the voltage signal is lower than a preset value, the microcontroller controls the motor 15 to return to an initial state and enter a standby mode.
The bottom of the inner cylinder 13 is fixedly connected with a rotary flange 17, and the rotary flange 17 is connected with a rotating shaft of the motor 15 through a coupler 7, so that a motor control device is fixed. In order to prevent the motor 15 from being polluted by oil stains and the like at the ground, the motor control device is wrapped and protected by the shell 1. In order to prevent the microbubble generating system from being polluted by the oil stain on the ground, the microbubble generating sheet 5 is separated from the inner cylinder gap 12 in the descending process of the carbon dioxide oil displacement and sealing tool, and the microbubble generating system stops working at the moment.
The upper end of the shell 1 of the carbon dioxide displacement and sealing tool disclosed in the embodiment is provided with a female head which can be connected with a male head of a drill rod or an oil pipe, the tool is enabled to vertically enter a well when the tool is used, and a sealer is arranged at the upper end of the tool. When the carbon dioxide gas is continuously injected, the pressure in the inner cylinder 13 is gradually increased and is transmitted to the pressure sensor 14 attached to the rotary flange 17, and when the pressure reaches a threshold value, the pressure sensor 14 converts the pressure variation into an electric signal, and the generated electric signal controls the motor 15 to start working through a connected electric wire. The motor rotating shaft is coaxially arranged with the coupler 7, when the motor 15 is started, the motor rotating shaft drives the rotating flange 17 to rotate through the coupler 7, the rotating flange 17 is fixedly connected with the bottom of the inner cylinder 13 to drive the inner cylinder 13 to rotate, a passage is formed between the microbubble generating system and the shell gap 4, the filter screen 6 filters impurities and particles in gas, the microbubble generating sheet 5 converts the carbon dioxide gas into carbon dioxide microbubbles and smoothly discharges the carbon dioxide microbubbles, and therefore the internal pressure is reduced. Through the process, carbon dioxide is efficiently input into the stratum in a micro-bubble mode, and the purposes of oil displacement and carbon dioxide sealing are achieved.
