[0022] A method for using a circulating dissolution detection device for processing a soluble bridge plug, comprising the following steps:

[0023] S1, with the water source in the storage tank filled with the water source in the drilling environment, the bridge plug is sleeved on the storage column, and the bearing disc is threadedly connected at the bottom end of the storage column. The storage column is put into the output pipeline along the output pipeline. The limiting disc on the storage column has an outer diameter larger than the diameter of the output pipeline. The storage column can be stably placed in the output pipeline. Then the valve on the storage tank is opened to discharge water into the output pipeline, so that the water source contacts the bridge plug. At the same time, the servo motor is started to drive the transmission wheel to rotate through the transmission rod, so that the transmission wheel drives the rotating block to rotate to drive the two pump gears inside the gear pump shell to rotate. At this time, the water flowing into the water storage tank can be pumped into the storage tank again to form a stable water flow system.

[0024] S2, with the water source continuously contacting the bridge plug, the bridge plug part begins to dissolve. At this time, in order to simulate the change of water flow in natural environment, the worker rotates the adjusting rod clockwise. Because the outer wall of the adjusting rod is provided with two thread grooves with opposite thread directions, the adjusting rod rotates, and the two thread grooves respectively drive the left and right patches to move away from each other. The left and right patches are not attached to the inner wall of the box at this time. The adjusting rod is in an adjustable state. The worker manually pushes the adjusting rod downward. The adjusting rod drives the hinged block to slide downward on the lever through the adjusting block. The fulcrum of the adjusting lever rotates, so that the swing amplitude of the upper end of the lever will become smaller or larger with the up and down position of the hinged block, thereby controlling the swing amplitude of the top end of the lever. After adjustment is completed, the worker reversely rotates the adjusting rod. The left and right patches on the adjusting rod move inward relative to each other, and gradually attach to the inner wall of the box. The adjusting rod is locked through the extrusion force of the left and right patches attached to each other.

[0025] S3, the worker can start the transmission motor, and the transmission motor drives the bearing column to rotate. Because the bearing column, the outer ring and the inner ring are connected together through the connecting rod, the three rotate together. With the clockwise rotation of the bearing column, the actuating rod in the inner guide groove will gradually contact the inner guide rod. At this time, because the initial state of the outer guide rod is attached to the right side end face of the notch, with the rotation of the inner guide rod, the inner guide rod is in contact with the actuating rod, thereby driving the inner guide rod to rotate and pull the torsion spring. At the same time, because the outer guide rod is attached to the right side end face of the notch, the actuating rod passes to the left side of the notch, and because the inner guide rod continuously extrudes the actuating rod, the inner guide rod is extruded to the left at this time, and the top end thereof is attached to the left side end face of the notch. This makes the actuating rod be blocked by the inner guide rod when passing to the left side of the notch at the right end of the inner guide groove, and the actuating rod cannot enter the inner guide groove again, but can continue to pass to the left side along the side wall of the inner guide rod and enter the outer guide groove;

[0026] When the toggle lever enters from the right end of the inner guide groove to the left end of the outer guide groove, the toggle lever generates a forward pushing force, the toggle lever pushes forward through the pushing plate, the toggle plate drives the bottom end of the lever to deviate to the right side, the lever rotates on the adjusting block through the setting of the hinge block, and since the lever is in sliding connection with the hinge block, the lever slides in the hinge block during rotation, but does not affect the rotation of the lever, and the up-down movement of the hinge block can adjust the pivot point of the lever, so that the rotation state of the lever can be controlled;

[0027] Then, as the top end of the lever rotates to the left, the lever pulls the sliding block to slide on the pulling plate, and at the same time, the lever drives the pulling plate to move downward, and the pulling plate synchronously drives the transmission wheel to move downward. Since the rotating block is a conical structure, the outer diameter of the rotating block becomes larger as it rotates downward, so that the transmission ratio between the rotating block and the transmission wheel gradually increases, the rotation speed increases, and thus the water pumping speed of the gear pump also increases, thereby increasing the flow rate of the water flow, facilitating the observation of the dissolution state of the bridge plug by the staff, and observing the influence of the flow rate of the water flow on the dissolution of the bridge plug.

[0028] S4, then the bearing column continues to rotate slowly until it rotates one hundred and eighty degrees, at this time the toggle lever continues to move through the outer guide groove until the toggle lever contacts the outer guide rod, the outer guide rod is extruded by the toggle lever and deviates to the left, the outer guide rod pulls the torsion spring, prompting the outer guide rod to block the vacancy at the left end of the outer guide groove, preventing the toggle lever from entering the outer guide groove again, and the initial state of the inner guide rod is the same as that of the outer guide rod, both deviating to the right. At this time, the inner guide rod guides the toggle lever into the inner guide groove, the toggle lever drives the toggle plate to retreat and reset, and thus drives the lever to restore to a vertical state, when the top end of the lever is gradually vertical, the sliding block pushes the pulling plate to rise and reset, and thus the transmission wheel is reset to the initial state, the power ratio is restored, and the flow rate of the water flow is restored to the initial state. Through a certain time of accelerated flow rate, it is observed whether the dissolution speed of the bridge plug can be shortened, so that the staff can control the dissolution of the bridge plug when using the bridge plug;

[0029] At the same time, when the toggle lever is reset, the transmission motor is stopped.

[0030] S5. Finally, wait for the bridge plug to dissolve to the maximum extent. At this time, the water flow speed without the obstruction of the bridge plug reaches the maximum extent. The high-speed water flow impacts the fan blades to rotate, causing the fan blades to cooperate with the sealing shaft to drive the driven gear to rotate. When the rotating rod on the driven gear rotates to the maximum speed, the centrifugal force guiding the two swing arms also increases to the maximum, swinging the two swing arms to the highest point. When the swing arms swing upward, they contact the trigger cavity on the trigger sleeve and squeeze the trigger sleeve to rise. The top of the trigger sleeve squeezes the trigger plate to cause it to move forward. At this time, the forward movement of the trigger plate drives the telescopic spring rod on one side to rotate and contract. When the trigger plate continues to move forward, it pushes the telescopic spring rod to deflect and exceed the vertical state. The telescopic spring rod changes from a compressed state to a released state, pushing the trigger plate to the right, causing the display panel to move to the right, indicating that the dissolution is now complete. The staff can stop the device to drain the liquid in the output pipe and manually pull out the storage column. During the extraction process, the squeezing plate will push the trigger plate to the left again. After the storage column is pulled out, it is rinsed for subsequent use.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. When using this device, through the setting of the conical structure of the rotating block and the transmission wheel, different power changes can be achieved by changing the up and down positions of the transmission wheel, which is convenient for the staff to adjust the water flow rate;

[0033] 2. When using the device, through the arrangement of the adjustment rod, lever and hinge block, the staff uses the rotation adjustment of the lever to adjust the rotation angle of the lever, thereby adjusting the position of the transmission wheel through the lever;

[0034] 3. When using the device, through the setting of the swing arm, when the bridge plug is completely dissolved, the water flow rate is the largest, and the centrifugal force is used to swing the swing arm to switch the position of the display panel, making it convenient for staff to observe the current working status of the equipment.

[0059] In this embodiment, as shown in Figure 10 , Figure 13 , Figure 14 and Figure 15 , the adjusting mechanism 4 further comprises an outer ring 419 rotating in the box body 1. The bottom end of the outer ring 419 is fixedly connected with a connecting rod 420. The inner ring 421 is horizontally arranged at the inner ring of the outer ring 419.

[0069] In the embodiment, as shown in Figure 1 and Figure 2 The top end of the box body 1 is fixedly connected with a water storage tank 6, the outer wall of the water storage tank 6 is fixedly connected with a valve, and the valve is connected with the output pipeline 2, the inside of the box body 1 is provided with a water storage tank 7, the top end of the water storage tank 7 is connected with the output pipeline 2, and one side of the water storage tank 7 is connected with the water passing warehouse 42, and the water storage tank 6, the water storage tank 7 and the gear pump shell 41 are communicated, so that a stable water flow can be continuously formed.

[0070] In the embodiment, as shown in Figures 1 to 15 A use method of the circulating dissolution detection device for soluble bridge plug processing includes the following steps:

[0071] S1, with the water source in the water storage tank 6 filled with the drilling environment, the bridge plug is sleeved on the storage column 513, the bearing disc 517 is threadedly connected at the bottom end of the storage column 513, the storage column 513 is placed in the output pipeline 2, the outer diameter of the limiting disc 514 on the storage column 513 is greater than the diameter of the output pipeline 2, the storage column 513 can be stably placed in the output pipeline 2, then the valve on the water storage tank 6 is opened to discharge water into the output pipeline 2, so that the water source contacts the bridge plug, and the servo motor is started to drive the transmission wheel 45 to rotate through the transmission rod 46, so that the transmission wheel 45 drives the rotating block 44 to rotate to drive the two pump gears 43 in the gear pump shell 41 to rotate, at this time, the water flowing into the water passing warehouse 42 can be pumped into the water storage tank 6 again, forming a stable water flow system.

[0072] S2, with the water source continues to contact with the bridge plug, the bridge plug part begins to dissolve, at this time in order to simulate the change of water flow in the natural environment, the staff clockwise rotation adjusting rod 414, because the outer wall of adjusting rod 414 is provided with two thread groove with opposite direction thread, make adjusting rod 414 rotation, two thread groove respectively drive left patch 417 and right patch 418 away from each other, left patch 417 and right patch 418 not with the inner wall of box 1, at this time adjusting rod 414 can adjust state, manually push down adjusting rod 414, adjusting rod 414 through adjusting block 413 drive articulated block 412 down on lever 411, the fulcrum of adjusting lever 411 rotation, make the swing amplitude of lever 411 upper end will follow the up and down position of articulated block 412 and become small or become big, thereby control the swing amplitude of lever 411 top, after adjusting, the staff reverse rotation adjusting rod 414, left patch 417 and right patch 418 on adjusting rod 414 relative motion inward, gradually with the inner wall of box 1, through the extrusion force of left patch 417 and right patch 418 mutual adhesion, locking adjusting rod 414.

[0073] S3, as Figure 14 and Figure 15 shown, the staff can start transmission motor, transmission motor drive bearing column 423 rotation, because bearing column 423, outer ring 419, inner ring 421 through connecting rod 420 connected together, the three together rotation, with bearing column 423 clockwise rotation, located in the inner guide slot 425 in the dial rod 429 will gradually with the inner guide rod 428 contact, at this time because the initial state of outer guide rod 426 is with the right side end face of gap 422 adhesion, with the inner guide rod 428 rotation makes it with dial rod 429 contact, in turn promote the inner guide rod 428 rotation pull the torsion spring, at the same time because the outer guide rod 426 is with the right side end face of gap 422 adhesion, make dial rod 429 to the left through gap 422, and because the inner guide rod 428 continuously with dial rod 429 extrusion setting, at this time the inner guide rod 428 is extruded left, its top with the left side end face of gap 422 adhesion, this makes dial rod 429 in the right end of inner guide slot 425 to the left side of gap 422 through is blocked by inner guide rod 428, it can't enter inner guide slot 425 again, can continue to pass to the left along the side wall of inner guide rod 428, enter outer guide slot 424;

[0074] When the toggle lever 429 enters from the right end of the inner guide slot 425 to the left end of the outer guide slot 424, the toggle lever 429 generates a forward pushing force, the toggle lever 429 pushes forward through the pushing plate 430, the toggle plate 47 drives the bottom end of the lever 411 to deviate to the right side, the lever 411 rotates through the setting of the hinge block 412 on the adjusting block 413, and since the lever 411 is in sliding connection with the hinge block 412, the lever 411 slides in the hinge block 412 during the rotation of the lever 411, but does not affect the rotation of the lever 411, and the up and down movement of the hinge block 412 can adjust the axis point of the lever 411, so that the rotation state of the lever 411 can be controlled;

[0075] Then, due to the left rotation of the top end of the lever 411, the lever 411 pulls the sliding block 410 to slide on the pulling plate 49, and at the same time, the lever 411 drives the pulling plate 49 to move downward, and the pulling plate 49 synchronously drives the transmission wheel 45 to move downward. Since the rotating block 44 is a conical structure, the outer diameter of the rotating block 44 becomes larger as it rotates downward, so that the transmission ratio between the rotating block 44 and the transmission wheel 45 gradually increases, the rotation speed increases, and thus the water pumping speed of the gear pump also increases, thereby increasing the flow rate of the water flow, facilitating the observation of the dissolution state of the bridge plug by the staff, and observing the influence of the flow rate of the water flow on the dissolution of the bridge plug.

[0076] S4, as shown in Figure 14 and Figure 15 shown, then the bearing column 423 continues to rotate slowly until it rotates one hundred and eighty degrees, at which time the toggle lever 429 continues to move through the outer guide slot 424 until the toggle lever 429 contacts the outer guide rod 426, the outer guide rod 426 is extruded by the toggle lever 429 and deviates to the left, the outer guide rod 426 pulls the torsional spring and causes the outer guide rod 426 to block the vacancy at the left end of the outer guide slot 424, preventing the toggle lever 429 from entering the outer guide slot 424 again, and the initial state of the inner guide rod 428 is the same as that of the outer guide rod 426, both deviating to the right. At this time, the inner guide rod 428 guides the toggle lever 429 to enter the inner guide slot 425, at which time the toggle lever 429 drives the toggle plate 47 to retreat and reset, thereby driving the lever 411 to return to the vertical state, when the top end of the lever 411 gradually becomes vertical, the sliding block 410 can push the pulling plate 49 to rise and reset, thereby resetting the transmission wheel 45 to the initial state, restoring the power ratio, and restoring the flow rate of the water flow to the initial state. Through a certain time of accelerated flow rate, it is observed whether the dissolution speed of the bridge plug can be shortened, so that the staff can control the dissolution of the bridge plug when using the bridge plug;

[0077] At the same time, when the toggle lever 429 resets, the transmission motor stops.

[0078] S5, finally, wait for the bridge plug to dissolve to the maximum extent, at this time there is no bridge plug to block the flow velocity to the maximum extent, through the high-speed water flow impact fan 53 rotation, prompting the fan 53 with sealing shaft 51 driven gear 54 rotation, when the rotating rod 55 on the driven gear 54 rotates to the maximum speed, guide two swing arm 56 received centrifugal force also increases to the maximum, two swing arm 56 fling to the highest point, swing arm 56 fling up, it is in contact with the trigger cavity 59 on the trigger sleeve 58 and extrusion trigger sleeve 58 rising, trigger sleeve 58 top extrusion trigger plate 510 to make it move forward, at this time through the trigger plate 510 forward drive one side of the telescopic spring rod 512 rotation and shrink, when the trigger plate 510 continues to move forward in the process of pushing telescopic spring rod 512 deflection and more than the vertical state, telescopic spring rod 512 from the compression state to release state, push the trigger plate 510 to the right, so that the display plate 511 to the right, indicating that the completion of the dissolution at this time, the staff can stop the device to output pipe 2 in the liquid discharge, and manually store column 513 pull out, in the process of pulling out, extrusion plate 516 will again push the trigger plate 510 to the left, pull out the storage column 513, after flushing, in order to facilitate the subsequent use.

[0079] Finally, it should be noted that the above content is only used to illustrate the technical solutions of the present application, rather than limit the scope of protection of the present application, the ordinary skill in the art of the technical solutions of the present application for simple modification or equivalent replacement, do not deviate from the essential and scope of the present application technical scheme.
