Description

Technical Field

[0001] This utility model relates to the field of shale gas extraction technology, specifically to a shale gas agent water multi-media nano-displacement device. Background Technology

[0002] In the process of shale gas extraction, the submersible pump is a key device to improve the recovery rate of shale gas. The device mixes nanomaterials with water and other media to form a mixture and injects it into the shale, reducing the interfacial tension of the shale and making it easier for shale gas to separate from the rock formation.

[0003] Traditional anti-submarine gas (ASG) devices have simple mixing structures when mixing various media such as anti-submarine agents and water, which cannot achieve nanoscale fine mixing. Insufficient mixing makes it difficult for the anti-submarine agents to fully exert their synergistic effect, affecting the anti-submarine gas effect and reducing the recovery rate of shale gas. At the same time, the flow control components of traditional devices have relatively crude structures, making it difficult to accurately control the injection flow rate of anti-submarine agents and water. Inaccurate flow control will lead to resource waste and may also affect the stability of shale gas. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0024] Please see Figures 1-6 This utility model discloses a shale gas agent water multi-media nano-displacement device, including a working platform 1 and a control console 2 mounted on the working platform 1, and also includes a multi-media flow control component 3, a primary mixing component 4, a nano-high-precision mixing component 5, an injection component 6, and a moving component 7, wherein:

[0025] The work platform 1 is equipped with a push handle 11, and a box groove 12 is provided on one side of the push handle 11;

[0026] Please refer to the appendix. Figure 2 The multi-media flow control component 3 includes several equally spaced storage tanks 31. An ultrasonic level sensor 32 is fixed to the top of the storage tank 31 by screws. The ultrasonic level sensor 32 is electrically connected to the display 33. An electromagnetic metering pump 34 and an electric regulating valve 35 are connected to one side of the storage tank 31 through a pipe. Specifically, the ultrasonic level sensor 32 displays the liquid level data of the storage tank 31 on the display 33 for easy observation by the operator. The electromagnetic metering pump 34 provides pumping power and monitors the liquid flow rate, feeding back to the control console 2. The flow rate is adjusted by the opening degree of the electric regulating valve 35.

[0027] Please refer to the appendix. Figure 4The high-precision nano-mixing component 5 includes a high-precision mixing tube 51, inside which is a nano-microporous plate 52. The nano-microporous plate 52 divides the high-precision mixing tube 51 into a mixing chamber 511 and a liquid outlet chamber 512. An ultrasonic generator 53 is provided on the top of the high-precision mixing tube 51.

[0028] The storage tank 31 is fixed to the bottom of the tank 12 by bolts, the display 33 is fixed to one side of the storage tank 31 by bolts, and the control console 2 is electrically connected to the electromagnetic metering pump 34 and the electric regulating valve 35.

[0029] In this embodiment, the switching valve 45 is opened, and the mixing medium enters the mixing chamber 511 of the high-precision mixing tube 51. When the medium passes through the nanoporous plate 52, it achieves nanoscale fine mixing under pressure. At the same time, under the high-frequency vibration of the ultrasonic generator 53, the mixing uniformity of the medium is further promoted, and the movement of medium molecules is accelerated, so that the medium passes through the nanoporous plate 52 quickly to complete nanoscale fine mixing. Example 2

[0030] Based on the above embodiment 1, please refer to the appendix. Figure 3 , Figure 5 as well as Figure 6 One end of the electric regulating valve 35 is connected to the electromagnetic metering pump 34, and the other end is connected to the manifold 36, which is connected to the mixing tank 41.

[0031] The primary mixing component 4 includes a stirring motor 42, which is fixed at the bottom of the mixing tank 41. One end of the stirring motor 42 is connected to a spiral blade 43. The spiral blade 43 is close to the inner wall of the mixing tank 41 and rotates in coordination. Specifically, when the spiral blade 43 rotates, it carries the water from the lower layer upward and squeezes it upward. The water from the upper layer is squeezed and moves downward, thereby achieving a better tumbling and mixing effect.

[0032] The mixing tank 41 is suspended and fixed on the mounting bracket 44. One side of the mixing tank 41 is connected to one end of the switch valve 45, and the other end of the switch valve 45 is connected to the mixing chamber 511. One end of the ultrasonic generator 53 extends into the mixing chamber 511. Specifically, the high-frequency vibration of the ultrasonic generator 53 improves the mixing uniformity of the medium.

[0033] The injection assembly 6 includes a high-pressure plunger pump 61. One side of the high-pressure plunger pump 61 is connected to the liquid outlet chamber 512 via a pipeline, and the other side is connected to the injection pipeline 62 via a flange. Specifically, the high-pressure plunger pump 61 can provide sufficient pressure to inject the uniformly mixed flooding medium into the shale gas reservoir.

[0034] The bottom of the work platform 1 is provided with a steering wheel 71, which is mounted on a wheel frame 72 and rotates in cooperation with it. The top of the wheel frame 72 is fitted with a steering sleeve 73 and rotates in cooperation with it. An auxiliary wheel 74 is provided on one side of the steering wheel 71.

[0035] In this embodiment, when the working platform 1 moves, the steering wheel 71 follows the wheel frame 72 and rotates freely in the steering sleeve 73, thereby realizing the steering adjustment of the working platform 1. With the help of the auxiliary wheel 74, the working platform 1 can carry the equipment and adjust its position at will, which improves the ease of use of the equipment. The stirring motor 42 drives the spiral blade 43 to rotate, so that the mixed liquid in the mixing tank 41 continuously rolls and mixes, realizing primary mixing.

[0036] The working principle and usage process of this utility model are as follows: First, the anti-submarine agent, water and other auxiliary media are stored in the storage tank 31. The ultrasonic liquid level sensor 32 monitors the liquid level in real time and transmits it to the display 33 for display, so that the operator can observe and add in real time.

[0037] Push the push handle 11, and use the steering wheel 71 and auxiliary wheel 74 to move the working platform to the shale gas development drilling site. Then insert the injection pipe 62 into the borehole. According to the shale gas extraction requirements, set the mixing ratio of the submersible discharging medium, injection flow rate and other parameters through the control console 2. Start the electromagnetic metering pump 34 to extract the medium from the storage tank 31 and feed back the medium flow rate to the control console 2 in real time. The control console 2 controls the opening and closing of the electric regulating valve 35 to control the mixing ratio of each medium and the total injection flow rate.

[0038] Each medium enters the mixing tank 41 through the manifold 36. The stirring motor 42 is started to drive the spiral blades 43 to rotate, causing the mixed liquid to continuously tumble and mix, achieving primary mixing. Then, the switch valve 45 is opened, and the mixed medium enters the mixing chamber 511 of the high-precision mixing tube 51. When the medium passes through the nanoporous plate 52, it achieves nanoscale fine mixing under pressure. At the same time, under the high-frequency vibration of the ultrasonic generator 53, the mixing uniformity of the medium is further promoted, and the movement of medium molecules is accelerated, so that the medium passes through the nanoporous plate 52 quickly, completing nanoscale fine mixing.

[0039] Finally, the high-pressure plunger pump 61 extracts the mixed medium from the liquid outlet chamber 512 and injects the liquid into the depth of the shale gas development borehole using the injection pipe 62.
