Description

Technical Field

[0001] The present invention relates to the technical field of geothermal drilling, and in particular to a geothermal drilling device based on well control. Background Art

[0002] Geothermal drilling is used for drilling geothermal steam and geothermal water. It is an important special technology and a necessary means for exploring and exploiting geothermal fluids. For high-temperature geothermal fields, the drilling depth is generally between 500 meters and 2000 meters, a small number exceeds 2000 meters, and most are between 600 and 900 meters. For low-temperature conductive geothermal fields, the average depth is 1800 meters, and the drilling depth of geopressured geothermal fields can be as deep as 6000 meters.

[0003] For example, a geothermal well drilling device with publication number CN118532125A can drive the moving wheel mechanism to rise and separate from the ground through the lifting mechanism, and can be buffered and damped through the shock absorbing mechanism, with good damping effect and good stability. After the drilling work is completed, the moving wheel mechanism can be driven down by the lifting mechanism to contact the ground, so that the shock absorbing mechanism is separated from the ground, so that the geothermal well drilling device can be moved away, and the maneuverability is good. Through the linkage and coordination of the lifting mechanism, the moving wheel mechanism and the shock absorbing mechanism, the geothermal well drilling device has good maneuverability and is easy to move. It can also buffer and absorb shock during drilling work, and the moving wheel mechanism is separated from the ground to improve the stability of the device and prevent the position from moving. However, in actual use, as the geothermal drilling continues to go deeper, when the drilling process goes deep into the underground heat reservoir, there are some gases in the underground heat reservoir. As the drilling proceeds, these gases may emerge from the ground as the drilling proceeds. These gases may contain a small amount of hydrogen sulfide gas, which is highly toxic. If these small amounts of hydrogen sulfide gases are not purified in time, in order to ensure safety, it is necessary to shut down and evacuate in time, waiting for the hydrogen sulfide gas to evaporate with the air. However, when a small amount of hydrogen sulfide gas is present, the device must be shut down, which will reduce the drilling efficiency and there are certain usage defects.

[0004] Therefore, we propose a geothermal drilling device based on well control to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a geothermal drilling device based on well control to solve the problem raised in the above-mentioned background technology that as geothermal drilling continues to go deeper, when drilling deep into the underground heat reservoir, there are some gases in the underground heat reservoir. As drilling proceeds, these gases may emerge from the ground. These gases may contain some small amounts of hydrogen sulfide gas, which is highly toxic. If these small amounts of hydrogen sulfide gas are not purified in time, in order to ensure safety, it is necessary to shut down and evacuate in time, waiting for the hydrogen sulfide gas to evaporate with the air. However, when there is a small amount of hydrogen sulfide gas, the machine must be shut down, which will reduce the working efficiency of drilling.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the geothermal drilling device based on well control is provided with a purification component at the bottom of the base, so that a small amount of gas emitted during drilling can be purified, thereby preventing a small amount of hydrogen sulfide gas from emitting and affecting the safety of the workers, and preventing downtime from affecting the drilling efficiency, thereby improving practicality; 1. A purification component is set at the bottom of the base. Drilling is carried out through the drilling mechanism. Continuous excavation during the drilling process will generate vibration, causing the base to vibrate up and down continuously. The damping rod and the buffer spring are used for buffering. The base will move up and down slightly during the buffering process. After the base moves, it drives the rotating shaft to move. After the rotating shaft moves, the engagement of the driven gear and the toothed plate causes the rotating shaft to rotate slightly back and forth. The rotation amplitude of the rotating shaft is small, but the length of the swing rod is long, so that the swing amplitude of the swing rod will not be too small when the rotating shaft rotates slightly. After the swing rod swings, the movable plate can be pushed to move by the roller. After the movable plate moves, it slides on the support rod and can stretch the telescopic spring. The reciprocating rotation of the rotating shaft can make the movable plate move up and down. During the up and down reciprocating movement of the movable plate, The two racks continuously drive the two rotating gears to rotate, so that the rotating rod rotates, and then the two sleeves are synchronously rotated in opposite directions through the cooperation of the first pulley and the second pulley. During the descending process of the movable plate, one sleeve on one side can drive the rotating shaft to rotate through the engagement of the ratchet groove and the latching teeth on one side. After the sleeve on the other side rotates, the ratchet groove can toggle the latching teeth to rotate. During the upward movement of the movable plate, the ratchet groove on the sleeve on the other side cooperates with the latching teeth so that the rotation of the sleeve on the other side can drive the rotating shaft to rotate, and the rotation direction of the sleeve on the other side changes after the movable plate moves up, and then the reciprocating movement of the movable plate can make the rotating shaft rotate continuously in one direction, and the two sets of ratchet grooves and the latching teeth are in opposite directions, so that the rotation directions of the two rotating shafts are opposite, so that the two rotating shafts can rotate continuously during the buffering process of the base; 2. After the two rotating shafts rotate, the driving gear and the teeth on the rotating ring can be meshed to drive the rotating ring to rotate. During the rotation of the rotating ring, the limit ring is driven to slide in the limit ring groove for limiting. After the rotating ring rotates, the two cylinders can be driven to rotate continuously. After the cylinder rotates continuously, the gas emitted from the drilling can enter the cylinder through the air inlet pipe. The gas can be purified through the silica gel layer and the activated carbon layer. A small amount of hydrogen sulfide gas can be purified to avoid harm to the staff; 3. When the rotating ring drives the two cylinders to rotate in a circle, the installed gear can drive the rotating rod to rotate by meshing with the outer gear ring. After the rotating rod rotates, it can drive the rotating blades to rotate. After the rotating blades rotate, they can adsorb the gas and drain the gas to speed up the purification of the gas. The cylinder can rotate in a circle around the drilling area to expand the adsorption range of the gas. After purification, the gas can reach the bottom of the base. The concentration of hydrogen sulfide in the gas is detected by a hydrogen sulfide gas detector. If a large amount of hydrogen sulfide emerges during the drilling process and cannot be completely cleaned up by the purification component, the real-time detection of the hydrogen sulfide gas detector can sound an alarm to the staff, reminding them to evacuate in time to avoid safety accidents.

[0026] Example 1 like Figure 1-Figure 8As shown, drilling is performed by the drilling mechanism 101. During the drilling process, continuous excavation will generate vibration, causing the base 1 to continuously vibrate up and down. The damping rod 103 and the buffer spring 106 are used for buffering. During the buffering process, the base 1 will generate a slight up and down movement. After the base 1 moves, it drives the rotating shaft 202 to move. After the rotating shaft 202 moves, the engagement between the driven gear 204 and the tooth plate 203 causes the rotating shaft 202 to slightly reciprocate. The rotation amplitude of the rotating shaft 202 is small, but the length of the swing rod 206 is long, so that when the rotating shaft 202 rotates slightly, the swing amplitude of the swing rod 206 will not be too small. After the swing rod 206 swings, it can push the movable plate 209 to move through the roller 208. After the movable plate 209 moves, it can slide on the support rod 210 and stretch the telescopic spring 211. The reciprocating rotation of the rotating shaft 202 can make the movable plate 209 reciprocate up and down. During the reciprocating movement of the movable plate 209 up and down, the two rotating gears 216 can be continuously driven to move. The wheel 217 rotates, causing the rotating rod 214 to rotate, and then the two sleeves 222 rotate synchronously in opposite directions through the cooperation of the first pulley 218 and the second pulley 224. During the descent of the movable plate 209, the sleeve 222 on one side can drive the rotating shaft 219 to rotate through the engagement of the ratchet groove 225 and the latching tooth 227 on one side. After the sleeve 222 on the other side rotates, the ratchet groove 225 can drive the latching tooth 227 to rotate. During the upward movement of the movable plate 209, the ratchet groove 225 on the sleeve 222 on the other side can be engaged with the latching tooth 227 on the other side. Cooperating with the latch tooth 227, the rotation of the sleeve 222 on the other side can drive the rotation of the rotating shaft 219, and after the movable plate 209 moves up, the rotation direction of the sleeve 222 on the other side changes, and then the reciprocating movement of the movable plate 209 can make the rotating shaft 219 continuously rotate in a reverse direction. The two sets of ratchet grooves 225 are in opposite directions to the latch tooth 227, so that the rotation directions of the two rotating shafts 219 are opposite, and then the two rotating shafts 219 can continuously rotate during the buffering process of the base 1.

[0027] A driving gear 228 is fixedly installed at one end of the two rotating shafts 219 that are close to each other, and a fixed cylinder 229 is fixedly installed at the bottom center of the base 1, and a rotating ring 230 is movably connected to the outer bottom of the fixed cylinder 229, and a limiting ring 231 is fixedly installed on the inner side of the rotating ring 230, and a limiting ring groove 232 is provided at the outer bottom of the fixed cylinder 229, and the limiting ring 231 is slidably connected to the limiting ring groove 232; A plurality of teeth 233 are fixedly mounted on the bottom of the rotating ring 230, and the two driving gears 228 are meshed and connected with the teeth 233, and the directions of the latch teeth 227 on the two sets of rotating shafts 219 are opposite to the directions of the two sets of ratchet grooves 225; A cylinder 234 is symmetrically installed on both sides of the rotating ring 230, and a mounting rod 236 is symmetrically installed inside the cylinder 234, and an air intake pipe 235 is connected to the bottom of the cylinder 234. At the same time, a rotating rod 237 is rotatably connected to the inside of the two mounting rods 236, and an activated carbon layer 240 and a silica gel layer 239 are fixedly installed on the upper part of the cylinder 234, and the rotating rod 237 is rotatably connected to the activated carbon layer 240 and the silica gel layer 239, and a rotating blade 238 is fixedly installed on the bottom of the rotating rod 237.

[0028] Example 2 like Figure 4-Figure 5 and Figure 9-10 As shown, after the two rotating shafts 219 rotate, the driving gear 228 can mesh with the teeth 233 on the rotating ring 230, so as to drive the rotating ring 230 to rotate. During the rotation of the rotating ring 230, the limiting ring 231 is driven to slide in the limiting ring groove 232 for limiting. After the rotating ring 230 rotates, the two cylinders 234 can be driven to rotate continuously. After the cylinder 234 rotates continuously, the gas emitted from the drilling can enter the cylinder 234 through the air inlet pipe 235, and the gas can be purified by the silica gel layer 239 and the activated carbon layer 240. A small amount of hydrogen sulfide gas can be purified to avoid harm to the staff.

[0029] A mounting gear 241 is fixedly mounted on the top of the two rotating rods 237 , and an outer gear ring 242 is fixedly mounted on the outer upper part of the fixing cylinder 229 , and the two mounting gears 241 are meshedly connected with the outer gear ring 242 .

[0030] Example 3 like Figure 4-Figure 5 and Fig.10 As shown, the rotating ring 230 drives the two cylinders 234 to rotate in a circle, and the mounting gear 241 can drive the rotating rod 237 to rotate by meshing with the outer gear ring 242. After the rotating rod 237 rotates, it can drive the rotating blades 238 to rotate. After the rotating blades 238 rotate, they can adsorb the gas, drain the gas, and speed up the purification of the gas. The cylinder 234 can rotate in a circle around the drilling area to expand the adsorption range of the gas. After purification, the gas can reach the bottom of the base 1. The concentration of hydrogen sulfide in the gas is detected by the hydrogen sulfide gas detector 107. If a large amount of hydrogen sulfide emerges during the drilling process and cannot be completely cleaned up by the purification component 2, the real-time detection of the hydrogen sulfide gas detector 107 can be used to issue an alarm to the staff, reminding them to evacuate in time to avoid safety accidents.

[0031] Working principle: When using the geothermal drilling device based on well control, first, according to Figure 1-Figure 10As shown, in order to prevent the formation pressure, temperature, fluid and other parameters from getting out of control during the drilling process, pressure control, temperature control, fluid control and wellbore structure control are required. These measures are aimed at ensuring the safety, efficiency and environmental protection of the drilling operation. The drilling is carried out by the drilling mechanism 101. The continuous excavation during the drilling process will generate vibration, causing the base 1 to continuously vibrate up and down. The damping rod 103 and the buffer spring 106 are used for buffering. The base 1 will produce a slight up and down movement during the buffering process. After the base 1 moves, it drives the rotating shaft 202 to move. The rotating shaft 2 After the rotation of the rotating shaft 202, the driven gear 204 and the tooth plate 203 are meshed to make the rotating shaft 202 rotate slightly back and forth. The rotation amplitude of the rotating shaft 202 is small, but the length of the swing rod 206 is long, so that the swing amplitude of the swing rod 206 will not be too small when the rotating shaft 202 rotates slightly. After the swing rod 206 swings, the movable plate 209 can be pushed to move by the roller 208. After the movable plate 209 moves, it slides on the support rod 210 and the telescopic spring 211 can be stretched. The reciprocating rotation of the rotating shaft 202 can make the movable plate 209 reciprocate up and down During the reciprocating movement of the movable plate 209, the two racks 216 can continuously drive the two rotating gears 217 to rotate, so that the rotating rod 214 rotates, and then the first pulley 218 and the second pulley 224 cooperate to make the two sleeves 222 rotate synchronously in opposite directions. During the descent of the movable plate 209, the sleeve 222 on one side can drive the rotating shaft 219 to rotate through the engagement of the ratchet groove 225 and the latching tooth 227 on one side. After the sleeve 222 on the other side rotates, the ratchet groove 225 can drive the latching tooth 227 to rotate, and the movable plate 209 moves upward. During the shifting process, the ratchet groove 225 on the sleeve 222 on the other side cooperates with the latch teeth 227 so that the sleeve 222 on the other side rotates to drive the rotating shaft 219 to rotate, and after the movable plate 209 moves up, the rotation direction of the sleeve 222 on the other side changes, and then the reciprocating movement of the movable plate 209 can make the rotating shaft 219 rotate continuously in one reverse direction, and the two sets of ratchet grooves 225 and the latch teeth 227 are in opposite directions, so that the rotation directions of the two rotating shafts 219 are opposite, so that the two rotating shafts 219 can rotate continuously during the buffering process of the base 1; After the two rotating shafts 219 rotate, the driving gear 228 can mesh with the teeth 233 on the rotating ring 230 to drive the rotating ring 230 to rotate. During the rotation of the rotating ring 230, the limiting ring 231 is driven to slide in the limiting ring groove 232 for limiting. After the rotating ring 230 rotates, the two cylinders 234 can be driven to rotate continuously. After the cylinder 234 rotates continuously, the gas emitted from the drilling can enter the cylinder 234 through the air inlet pipe 235. The gas can be purified by the silica gel layer 239 and the activated carbon layer 240. A small amount of hydrogen sulfide gas can be purified to avoid harm to the staff. During the process of the rotating ring 230 driving the two cylinders 234 to rotate in a circle, the mounting gear 241 can be installed by The meshing of the outer gear ring 242 drives the rotating rod 237 to rotate, and the rotating rod 237 can drive the rotating blade 238 to rotate. After the rotating blade 238 rotates, it can adsorb the gas, drain the gas, and accelerate the purification of the gas. The cylinder 234 can rotate around the drilling area in a circle to expand the adsorption range of the gas. The gas can reach the bottom of the base 1 after purification, and the concentration of hydrogen sulfide in the gas is detected by the hydrogen sulfide gas detector 107. If a large amount of hydrogen sulfide emerges during the drilling process and cannot be completely cleaned up by the purification component 2, the real-time detection of the hydrogen sulfide gas detector 107 can issue an alarm to the staff, reminding the staff to evacuate in time to avoid safety accidents.
