Description

Technical Field

[0001] The present invention relates to the technical field of oil production, and in particular to oil production equipment. Background Art

[0002] Petroleum is a fluid mineral buried deep underground. Initially, people called the oily liquid minerals produced in nature petroleum, the combustible gas natural gas, and the solid combustible oily minerals asphalt. With the in-depth study of these minerals, it was realized that they are all hydrocarbon compounds in composition and are related to each other in genesis, so they are collectively called petroleum. In September 1983, the 11th World Petroleum Congress proposed that petroleum is a complex mixture of gaseous, liquid and solid hydrocarbon compounds and a small amount of impurities that exist in nature. Therefore, petroleum extraction also includes natural gas extraction. Petroleum extraction technology includes logging engineering, drilling engineering, oil production engineering and oil and gas gathering and transportation engineering.

[0003] The application number CN202310842833.1 disclosed an anti-clogging oil extraction drilling equipment, including a base frame, a bottom plate on both sides of the base frame, a sleeve 1 passing through the bottom plate, a hydraulic cylinder on the upper end of the sleeve 1, the output end of the hydraulic cylinder is fixedly connected to the top plate, a fixing mechanism is provided below the sleeve 1, and a drilling mechanism and a suction mechanism that cooperate with each other are provided on the top plate. In the present invention, by controlling the movement of the telescopic components on the sleeve 1 and the sleeve 2, the sleeve 1 and the sleeve 2 are alternately rotated synchronously with the connecting shaft, so that the helical gear has two different motion modes, which can be applied to different crushing scenarios, greatly improving the crushing effect and efficiency of the soil blocks. After the crushing is completed, the soil blocks are sucked out in time by the suction mechanism, avoiding the problem of the soil blocks being too large to be discharged in time, and ensuring the continuity of the drilling process.

[0004] During the drilling process of current oil extraction equipment, when the drill pipe contacts the oil, there is a certain gap between the drill pipe and the drilled well. Therefore, the oil and harmful gases mixed in it will be discharged along the gap between the drill pipe and the well, which will not only cause a blowout, but also cause harm to the air and personnel. In addition, when the drill pipe contacts the soil layer, it will vibrate due to the reverse effect, which can easily cause the drill pipe to deviate during the drilling process and affect oil collection.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The propulsion mechanism is provided to drive the drill barrel to drill into the soil layer. When the drill barrel drills into oil, the sealing mechanism is provided to drive multiple baffles inside the drill barrel to slide outward and expand. At this time, the drilled well can be sealed to prevent oil from flowing out along the gap between the drill barrel and the well and causing a blowout.

[0020] 3. When the drill barrel penetrates into the soil layer, the guide component provided can limit the drill barrel to prevent the drill barrel from shifting due to vibration when drilling. In addition, the guide component can also drive the rotating stirring blade to move vertically back and forth, so that the stirring blade stirs the purification liquid and exhaust gas from different directions, thereby increasing the contact strength between the purification liquid and the exhaust gas, and facilitating further purification of the exhaust gas. Moreover, when the drill barrel is rotated out of the soil layer, the guide component can not only limit and guide the vertically moving drill barrel, but also clean the soil attached to the outside of the drill barrel, keeping the equipment tidy for subsequent use.

DETAILED DESCRIPTION

[0035] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0036] like Figures 1 to 5 As shown, this embodiment proposes an oil extraction equipment, including a mounting frame 1, a propulsion mechanism 2 arranged on the top of the mounting frame 1, and a drill pipe 3 arranged at the output end of the propulsion mechanism 2. The drill pipe 3 is provided with a sealing mechanism 4 that can slide outward relative to its axis to block oil and exhaust gas. The mounting frame 1 is provided with a purification mechanism inside for treating exhaust gas overflowed during drilling. The purification mechanism includes a gas collecting component 5 arranged on the inner bottom wall of the mounting frame 1 for collecting exhaust gas and a purification component 6 arranged on the inner side wall of the mounting frame 1 for purifying the collected exhaust gas. The mounting frame 1 is also provided with a limiting mechanism inside. The limiting mechanism includes a guide component 7 arranged on the inner top wall of the mounting frame 1 for guiding the drill pipe 3 and a water spray component 12 arranged between the guide component 7 and the mounting frame 1.

[0037] Before oil collection, it is necessary to drill out the oil from the soil layer first. A drill bit and a liquid sensor can be set at the bottom of the drill barrel 3. At this time, the propulsion mechanism 2 is used to drive the drill barrel 3 to rotate downward into the soil layer, and the drill bit is used to facilitate the drill barrel 3 to drill into the soil layer faster. When the drill barrel 3 contacts the oil, the liquid sensor will transmit the information of drilling into the oil to the external terminal. At this time, drilling is stopped, and the gap between the drill barrel 3 and the well is sealed by the provided sealing mechanism 4. Then, the drill barrel 3 is driven to rotate out of the well by the propulsion mechanism 2. At this time, the oil will not flow out along the gap between the drill barrel 3 and the well to cause a blowout, and some harmful gases will flow upward through the sealing mechanism 4. At this time, the gas collecting component 5 provided can not only seal the wellhead of the well The drill barrel 3 is not only sealed but also can collect the outflowing harmful exhaust gas into the purification component 6 for purification treatment. Moreover, the guide component 7 provided can not only block and limit the drill barrel 3 when it is rotated downward, preventing the drill barrel 3 from contacting the soil layer and being offset due to vibration, but also can clean the mud attached to the drill barrel 3 when the drill barrel 3 is rotated upward to separate from the soil layer. Moreover, the water spraying component 12 provided can spray water evenly on various positions outside the drill barrel 3, so that the drill barrel 3 can be cleaned thoroughly and then used later. In addition, in order to prevent foreign objects from colliding with the drill barrel 3 or other parts, a protective plate can be inserted on the outside of the mounting frame 1 to shield and protect the parts inside the mounting frame 1 to prevent foreign objects from contacting the parts and affecting the normal operation of the equipment.

[0038] Specifically, such as Figure 4 and Figure 5 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, the propulsion mechanism 2 further includes a bracket 101 provided on the top of the mounting frame 1, a first cylinder 201 provided on the top of the bracket 101, a first piston column 202 provided at the output end of the first cylinder 201, and a first motor 203 provided at the bottom of the first piston column 202, and the drill pipe 3 is connected to the output shaft of the first motor 203;

[0039] When the first cylinder 201 is started, the drill barrel 3 is driven to move downward through the first piston column 202. At this time, when the first motor 203 is started, the drill barrel 3 can be driven to rotate. Therefore, the drill barrel 3 can rotate while moving downward, and then cooperate with the drill bit to drill into the soil layer to find oil. In addition, movable grooves for moving the drill barrel 3 are provided on the top and bottom of the mounting frame 1.

[0040] like Figure 6 、 Figure 7 and Figure 12As shown, as a preferred embodiment, on the basis of the above-mentioned manner, the blocking mechanism 4 further includes a pressure plate 401 and a cross plate 402 arranged on the inner wall of the drill barrel 3, a plurality of slides 404 equidistantly slidably arranged on the top of the cross plate 402, a baffle 403 arranged at the bottom of the slide 404 and slidably connected to the side wall of the drill barrel 3, and a push-pull rod 405 movably arranged between the slide 404 and the pressure plate 401, and an extrusion component is further provided on the top of the pressure plate 401, wherein the extrusion component includes a third cylinder 406 arranged on the inner top wall of the drill barrel 3 and a third piston column 407 arranged at the output end of the third cylinder 406, and the bottom of the third piston column 407 is connected to the top of the pressure plate 401;

[0041] When the top of the drill barrel 3 contacts the oil and drilling is stopped, the third cylinder 406 is started by the control switch, and the pressure plate 401 is driven downward by the third piston column 407. At this time, the pressure plate 401 will push the slide 404 to slide around on the cross plate 402 through the push-pull rod 405, and then drive each baffle 403 to slide outward relative to the axis of the drill barrel 3. When the first motor 203 drives the drill barrel 3 to rotate, the high-speed rotating baffle 403 can block the gap between the drill barrel 3 and the well, preventing oil from overflowing upward along the gap and causing a blowout. At the same time, it can also block harmful exhaust gas mixed in the oil, preventing the harmful exhaust gas from being directly discharged to the outside, thereby improving safety.

[0042] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 8 As shown, as a preferred embodiment, based on the above-mentioned embodiment, the gas collecting component 5 further includes a second cylinder 501 symmetrically arranged on the inner wall of both ends of the mounting frame 1, a second piston column 502 arranged at the output end of the second cylinder 501, and an annular sealing sleeve 503 arranged on the second piston column 502, wherein a flow cavity is provided inside the annular sealing sleeve 503, and a notch for exhaust gas to enter is further provided at the bottom of the annular sealing sleeve 503;

[0043] The purification component 6 includes a purification box 601 provided on the inner top wall of the mounting frame 1, a stirring rod 603 slidably provided at the bottom of the purification box 601, a second motor 602 provided at the bottom of the stirring rod 603, a stirring blade 604 provided on the inner wall of the stirring rod 603 located in the purification box 601, and an air pipe 6011 provided between the annular sealing sleeve 503 and the purification box 601;

[0044] When the drill pipe 3 drills oil, the two second cylinders 501 inside the mounting frame 1 can also be started to work, and the second piston column 502 drives the two annular sealing sleeves 503 to press against the movable groove at the bottom of the mounting frame 1 to seal, preventing some oil and harmful gases from passing through the high-speed rotating baffle 403. If some harmful gases flow out, they will first enter the inside of the annular sealing sleeve, and then be passed into the purification box 601 filled with purification liquid through the air pipe 6011. The purification liquid can absorb the harmful substances in the exhaust gas, and the air pipe 6011 is located inside the purification box 601. One end of the opening is facing inward to prevent the purification liquid from flowing back into the air pipe 6011. At this time, the second motor 602 can also be started to drive the stirring rod 603 to rotate. The stirring rod 603 can drive the stirring blade 604 to rotate, stirring the purification liquid and exhaust gas in the purification box 601, increasing the contact and collision force between the exhaust gas and the purification liquid, thereby facilitating the purification liquid to completely absorb and purify the harmful substances in the exhaust gas.

[0045] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 8 、 Figure 9 、 Figure 10 ,and Figure 11 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, the guide component 7 includes a pushing component provided on the inner top wall of the mounting frame 1, a movable plate 701 provided at the output end of the pushing component, a guide sleeve 702 rotatably provided inside the movable plate 701, and a limit plate 9 provided on the top of the movable plate 701 and slidably connected to the purification box 601, wherein the pushing component includes a fourth cylinder 10 provided on the inner top wall of the mounting frame 1 and a fourth piston column 1001 provided at the output end of the fourth cylinder 10, and the bottom of the fourth piston column 1001 is connected to the top of the movable plate 701, and a transmission component is further provided between the top of the movable plate 701 and the stirring rod 603;

[0046] The transmission components include a rotating rod 704 rotatably arranged on the top of the movable plate 701 , a gear 705 arranged on the top of the rotating rod 704 , a tooth groove 703 arranged on the outside of the guide sleeve 702 , and a belt 8 arranged between the stirring rod 603 and the rotating rod 704 ;

[0047] When the drill barrel 3 moves, it will pass through the guide sleeve 702. At this time, the fourth cylinder 10 is started to work, and the movable plate 701 can be driven to move back and forth vertically through the fourth piston column 1001. In addition, the second motor 602 can drive the stirring rod 603 to rotate while driving the rotating rod 704 to rotate through the belt 8. The rotating rod 704 will drive the guide sleeve 702 with the tooth groove 703 to rotate in the opposite direction relative to the drill barrel 3 through the gear 705. Therefore, the guide sleeve 702 will move back and forth and reverse relative to the drill barrel 3, thereby blocking and limiting the vertically moving drill barrel 3 to prevent the drill barrel 3 from being offset due to vibration and affecting the drilling work. Moreover, when the drill barrel 3 drills oil and moves upward out of the soil layer, the guide sleeve 702 that moves back and forth and reverses relative to the drill barrel 3 can not only guide the drill barrel 3, but also scrape off some of the soil attached to the outside of the drill barrel 3, thereby keeping the surface of the drill barrel 3 clean and tidy for subsequent use.

[0048] In addition, the purification component 6 also includes an exhaust pipe 606 provided at the top of the purification box 601, a connecting rod 605 provided at the top of the stirring rod 603 and extending upward through the exhaust pipe 606, and a sealing plug 607 provided at the top of the connecting rod 605; while the second motor 602 drives the stirring rod 603 to rotate, the fourth cylinder 10 also drives the second motor 602 and the stirring rod 603 to move back and forth up and down through the movable plate 701, so that the stirring rod 603 drives the stirring blade 604 to move up and down and rotate inside the purification box 601, thereby stirring the purification liquid and the exhaust gas in multiple directions, further increasing the contact and collision force between the purification liquid and the exhaust gas, and facilitating the purification liquid to thoroughly adsorb and purify the harmful substances in the exhaust gas. In addition, the stirring rod 603 that moves up and down also drives the sealing plug 607 to move up and down through the connecting rod 605, intermittently blocking the exhaust pipe 606, so that the exhaust gas entering the purification box 601 is intermittently and slowly discharged, thereby increasing the residence time of the exhaust gas in the purification box 601, so that the purification liquid has enough time to thoroughly purify the exhaust gas.

[0049] In order to facilitate the cleaning of the outside of the drill tube 3, the water spraying component 12 includes a water tank 1201 arranged on the top of the mounting frame 1 and a water pipe 1202 arranged between the water tank 1201 and the movable plate 701. The movable plate 701 and the guide sleeve 702 are both provided with a cavity, and the outer wall of the guide sleeve 702 located inside the movable plate 701 is provided with a water inlet, and the inner wall of the guide sleeve 702 is provided with a plurality of drainage holes. Among them, the water tank 1201 is provided with a water pump whose output end is connected to the water pipe 1202, and the water pipe 1202 is a rubber hose made of elastic material; when the drill tube 3 is moved out of the soil layer and cleaned through the guide sleeve 702, the water pump in the water tank 1201 can also be started to discharge water into the cavity inside the movable plate 701 through the water pipe 1202, and the water will continue to flow into the guide sleeve 702 through the water inlet, and finally be sprayed to the outside of the drill tube 3 from the drainage holes on the inner wall of the guide sleeve 702, so that the guide sleeve 702 can clean the outside of the drill tube 3 more thoroughly.

[0050] like Figure 2 and Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a moving mechanism 11 is further provided on both sides of the bottom of the mounting frame 1, and the moving mechanism 11 includes a moving seat 1101, a support plate 1102 arranged on both sides of the top of the moving seat 1101, a fifth cylinder 1103 arranged on the top of the moving seat 1101, and a fifth piston column 1104 arranged between the output end of the fifth cylinder 1103 and the two support plates 1102; the entire equipment can be transferred by the moving wheel arranged at the bottom of the moving seat 1101, and when the equipment moves to the designated position, the fifth cylinder 1103 is started to work, and the mounting frame 1 can be driven up and down by the fifth piston column 1104, so that the bottom of the mounting frame 1 contacts the ground, thereby facilitating the control of the drill barrel 3 to drill into the soil layer to search for oil.

[0051] The working principle of the present invention is as follows: before oil collection, it is necessary to drill out oil from the soil layer first. At this time, the propulsion mechanism 2 is provided to drive the drill barrel 3 to be screwed downward into the soil layer. When the drill barrel 3 contacts the oil, the liquid sensor will transmit the information that the oil has been drilled to the external terminal. At this time, drilling is stopped, and then the third cylinder 406 is started by the control switch, and the pressure plate 401 is driven to move downward by the third piston column 407. At this time, the pressure plate 401 will push the slide 404 to slide in all directions on the cross plate 402 through the push-pull rod 405, and then drive each baffle 403 to slide outward relative to the axis of the drill barrel 3. When the first motor 203 drives the drill barrel 3 to rotate, the high-speed rotating baffle 403 can block the gap between the drill barrel 3 and the well, preventing the oil from overflowing upward along the gap and causing a blowout. At the same time, it can also block the harmful exhaust gas mixed in the oil, preventing the harmful exhaust gas from being directly discharged to the outside, thereby improving safety.

[0052] At the same time, the two second cylinders 501 inside the mounting frame 1 can be started to work, and the two annular sealing sleeves 503 are driven by the second piston column 502 to seal the movable groove at the bottom of the mounting frame 1 to prevent some oil and harmful gases from passing through the high-speed rotating baffle 403. If some harmful gases flow out, they will first enter the inside of the annular sealing sleeve, and then be passed into the purification box 601 filled with purification liquid through the air pipe 6011. The purification liquid can absorb the harmful substances in the exhaust gas, and the air pipe 6011 is located at one end of the purification box 601. The opening is facing forward to prevent the purification liquid from flowing back into the air pipe 6011. At this time, the second motor 602 can be started to drive the stirring rod 603 to rotate. The stirring rod 603 can drive the stirring blade 604 to rotate, stirring the purification liquid and exhaust gas in the purification box 601, increasing the contact and collision force between the exhaust gas and the purification liquid, thereby facilitating the purification liquid to completely absorb and purify the harmful substances in the exhaust gas.

[0053] When the drill tube 3 moves, it passes through the guide sleeve 702. At this time, the fourth cylinder 10 is started to work, and the movable plate 701 can be driven to move back and forth vertically through the fourth piston column 1001. In addition, the second motor 602 can drive the stirring rod 603 to rotate while driving the rotating rod 704 to rotate through the belt 8. The rotating rod 704 will drive the guide sleeve 702 with the tooth groove 703 to rotate in the opposite direction relative to the drill tube 3 through the gear 705. Therefore, the guide sleeve 702 will move back and forth and reverse relative to the drill tube 3, thereby blocking and limiting the vertically moving drill tube 3 to prevent the drill tube 3 from being offset due to vibration and affecting the drilling work. Moreover, when the drill tube 3 drills oil and moves upward out of the soil layer, the guide sleeve 702 that moves back and forth and reverses relative to the drill tube 3 can not only guide the drill tube 3, but also scrape off some of the soil attached to the outside of the drill tube 3, thereby keeping the surface of the drill tube 3 clean and tidy for subsequent use.

[0054] In addition, while the second motor 602 drives the stirring rod 603 to rotate, the fourth cylinder 10 will also drive the second motor 602 and the stirring rod 603 to move back and forth up and down through the movable plate 701. Therefore, the stirring rod 603 will drive the stirring blade 604 to move up and down and rotate inside the purification box 601, thereby stirring the purified liquid and the exhaust gas in multiple directions, further increasing the contact and collision force between the purified liquid and the exhaust gas, so that the purified liquid can thoroughly adsorb and purify the harmful substances in the exhaust gas. Moreover, the stirring rod 603 that moves up and down will also drive the sealing plug 607 to move up and down through the connecting rod 605, intermittently blocking the exhaust pipe 606, so that the exhaust gas entering the purification box 601 is discharged intermittently and slowly, thereby increasing the residence time of the exhaust gas in the purification box 601, so that the purified liquid has enough time to thoroughly purify the exhaust gas.

[0055] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; all technical solutions and improvements that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
