Description

Technical Field

[0001] The invention belongs to the field of geological exploration, in particular to an electromagnetic wave resistivity measuring device. Background Art

[0002] The main purpose of electromagnetic wave azimuthal resistivity measurement is to determine the oil, gas and water layers by determining the physical quantity of underground rock resistivity. During the drilling process, the transmitting antenna transmits electromagnetic waves to the surrounding strata, and the receiving antenna receives the electromagnetic waves after propagating through the strata. By measuring the amplitude and phase of the electromagnetic waves received by the receiving antenna, the resistivity of the strata can be calculated, thereby providing indispensable geological measurement parameters for drilling projects.

[0003] The patent with announcement number CN216406804U discloses a drilling azimuth and resistivity measurement device based on electromagnetic wave communication, which solves the problem that the current measuring instrument is greatly affected by the formation environment and affects the subsequent measurement results. It includes a drill rod, a drill bit is fixedly installed at the bottom of the drill rod, a buffer mechanism is installed on the outside of the drill rod, and a fixing mechanism is installed on the outside of the buffer mechanism; this patent cooperates between the mounting ring and the drill rod, so that when the measuring instrument body is fixed on the outside of the mounting ring, it can move up and down, and then when the measuring instrument body is affected by the formation environment and vibrates, through the cooperation between the top ring and the vertical rod and the bottom ring, the second spring can be expanded and contracted, and the force is absorbed by the elastic action of the second spring, so that the measuring instrument body can be buffered, thereby protecting the measuring instrument body.

[0004] However, the above technical solution still has the following deficiencies in practical application: The electromagnetic wave resistivity measurement module is carried by the drill pipe and drilled into the ground by the drill bit. When the electromagnetic wave resistivity measurement module reaches the appropriate depth of the borehole, the resistivity measurement is performed by emitting electromagnetic waves. However, since mud cake may be attached to the borehole wall, the mud cake is a layer of solid or semi-solid material formed around the hole wall by the mud during the drilling process. The thickness, resistivity and unevenness of the mud cake may affect the propagation of electromagnetic waves. Thicker mud cakes will absorb and attenuate more electromagnetic waves, resulting in a weakened measurement signal, which in turn affects the accuracy of the measurement results.

When the drill rod is outside the borehole, the box door can be opened to operate the electromagnetic wave resistivity measuring module. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] A stop cloth 12 is fixedly connected to one side of the upper end of the groove plate 13 and the telescopic plate 14 , and the stop cloth 12 is made of elastic material.

[0026] A connecting rod 18 is rotatably provided on one side of the groove plate 13 , a connecting rod 2 19 is rotatably provided on one end of the connecting rod 18 , and one end of the connecting rod 2 19 is rotatably connected to one side of the telescopic plate 14 .

[0027] A second motor 17 is fixedly connected to one side of the groove plate 13 , and an output end of the second motor 17 is fixedly connected to one end of a connecting rod 18 .

[0028] A connecting rod 20 is fixedly connected to both upper and lower ends of one side of the mounting plate 11 , a T-shaped rod 21 is slidably connected to one side of the connecting rod 20 , and an oscillation rod 16 is fixedly connected to the lower end of the T-shaped rod 21 .

[0029] A crank 23 is rotatably provided on one side of the connecting rod 20, and a slider 22 is rotatably provided on one end of the crank 23. The slider 22 is embedded in the slide groove of the T-bar 21 and is slidably connected thereto. A motor three 24 is fixedly connected to one side of the connecting rod 20, and the output end of the motor three 24 is fixedly connected to one end of the crank 23.

[0030] A collecting box 3 is fixedly connected to one side of the drill pipe 1 . The collecting box 3 is located below the connecting plate 8 . A camera 29 is also provided on the electromagnetic wave resistivity measuring module 5 .

[0031] Specifically, in the prior art, the electromagnetic wave resistivity measurement module 5 is carried by the drill rod 1, and the drill bit 2 is used to drill into the ground. When the electromagnetic wave resistivity measurement module 5 reaches the appropriate depth of the borehole, the resistivity measurement is performed by emitting electromagnetic waves. However, since the borehole wall may be attached with mud cake, which is a layer of solid or semi-solid material formed by mud around the hole wall during the drilling process, the thickness, resistivity and unevenness of the mud cake may affect the propagation of electromagnetic waves. Thicker mud cakes will absorb and attenuate more electromagnetic waves, resulting in a weakened measurement signal, thereby affecting the accuracy of the measurement results. Therefore, in order to avoid the above problems, when the present embodiment is in use, after the drill bit 2 and the drill rod 1 are drilled to a suitable depth, the state of the hole wall can be observed through the camera 29. When mud cakes are attached to the hole wall in the direction of electromagnetic wave emission, the motors 2 17 on both sides are used to simultaneously drive the connecting rods 18 and 19 to rotate, so that the telescopic plate 14 slides inside the groove plate 13 until the end of the telescopic plate 14 contacts the hole wall. At this time, the mud cake is between the two telescopic plates 14. Then, the motors 26 on both sides are started at the same time to rotate the gear 27, and under the action of the tooth block 28, By moving the displacement block 25 along the slide rail 30, the blades 15 on both sides can be moved close to the hole wall to scrape off the mud cake on the hole wall. After the mud cake is removed, the measurement can be performed again by emitting electromagnetic waves, thereby avoiding the situation that the mud cake attached to the hole wall affects the propagation of electromagnetic waves, resulting in the weakening of the measurement signal, thereby affecting the accuracy of the measurement result. In addition, when the drill bit 2 and the drill rod 1 are drilling, the telescopic plate 14 retracts and does not contact the hole wall, thereby avoiding the situation that the telescopic plate 14 is always in contact with the hole wall, thereby affecting the normal drilling work; When the blade 15 scrapes the mud cake on the hole wall, the mud cake will splash and may accumulate near the drill bit 2 or get stuck between the drill rod 1 and the well wall, increasing the risk of drill jamming and affecting the smooth progress of the measurement work. Therefore, in order to avoid this situation, when the telescopic plate 14 slides inside the groove plate 13, it will also drive the end of the blocking cloth 12 to move, causing the blocking cloth 12 to deform, and the blocking cloth 12 will cover the groove plate 13 and the upper end of the telescopic plate 14. When the mud cake splashes, it will only be concentrated in the cavity formed by the mounting plate 11, the groove plate 13, the telescopic plate 14, and the blocking cloth 12, so that the mud cake can be concentrated, and then the motor 10 is used to drive the rotating rod 9 to rotate, so that the mud cake in the cavity falls into the collection box 3, thereby realizing the centralized collection of the mud cake after cleaning, thereby avoiding the situation that when the blade 15 scrapes the mud cake, the mud cake splashes and accumulates near the drill bit 2 or gets stuck between the drill rod 1 and the well wall, increasing the risk of drill jamming and affecting the smooth progress of the measurement work; Furthermore, although the installation plate 11, the groove plate 13, the telescopic plate 14 and the blocking cloth 12 can be used to block the splashing mud cake, the blocking cloth 12 has a certain elasticity, so the splashing mud cake is more likely to adhere to the surface of the blocking cloth 12. When the mud cake falls from the blocking cloth 12 into the collecting box 3, the mud cake may not fall due to its strong adhesion, resulting in part of the mud cake remaining on the surface of the blocking cloth 12, thereby affecting the subsequent use of the blocking cloth 12. The mud cake may also accumulate on the blocking cloth 12, causing the mud cake to overflow, which will affect the drill rod 1 and the drill bit 2 again. Therefore, in order to avoid To avoid this situation, when the mud cake falls from between the baffle cloths 12, the motor 3 24 can be used to drive the crank 23 to rotate, so that the slider 22 can make a circular motion. At the same time, the slider 22 slides in the slide groove of the T-bar 21, so that the oscillation rod 16 can make a reciprocating motion. The impact of the oscillation rod 16 on the baffle cloth 12 can make the mud cake attached to the surface of the baffle cloth 12 fall off, thereby promoting the falling of the mud cake, and further avoiding the situation where the mud cake cannot fall from the baffle cloth 12 into the collection box 3 due to its strong adhesion, resulting in part of the mud cake always remaining on the surface of the baffle cloth 12, thereby affecting the subsequent use of the baffle cloth 12.

[0032] In this embodiment, Figure 6 As shown, a box door 7 is provided on one side of the shell 6.

[0033] Specifically, when the box door 7 is closed, the electromagnetic wave resistivity measurement module 5 is covered by the shell 6 and the box door 7, thereby preventing foreign objects such as gravel from hitting the electromagnetic wave resistivity measurement module 5 when the drill rod 1 and the drill bit 2 are in the borehole, causing damage to the electromagnetic wave resistivity measurement module 5, thereby improving safety. When the drill rod 1 is outside the borehole, the box door 7 can be opened to operate the electromagnetic wave resistivity measurement module 5.

[0034] Working principle: after the drill bit 2 and the drill rod 1 are drilled to a suitable depth, the state of the hole wall can be observed through the camera 29. When mud cakes are attached to the hole wall in the direction of electromagnetic wave emission, the motors 2 17 on both sides are used to simultaneously drive the connecting rods 18 and 19 to rotate, so that the telescopic plate 14 slides inside the groove plate 13 until the end of the telescopic plate 14 contacts the hole wall. At this time, the mud cake is between the two telescopic plates 14, and then the motors 26 on both sides are started at the same time to rotate the gear 27, and under the action of the tooth block 28, the displacement block 25 moves along the slide rail 30, so that the blades 15 on both sides can be moved close to the hole wall to scrape off the mud cakes on the hole wall. When the mud cakes are removed, the measurement can be performed again by emitting electromagnetic waves, thereby avoiding the situation that mud cakes are attached to the hole wall, which affects the propagation of electromagnetic waves, causes the measurement signal to weaken, and then affects the accuracy of the measurement results. In addition, when the drill bit 2 and the drill rod 1 are drilling, the telescopic plate 14 retracts and does not contact the hole wall, avoiding the telescopic plate 14 always When the blade 15 scrapes the mud cake from the hole wall, the mud cake will splash and may accumulate near the drill bit 2 or get stuck between the drill rod 1 and the well wall, increasing the risk of drill bit sticking and affecting the smooth progress of the measurement work. Therefore, in order to avoid this situation, when the telescopic plate 14 slides inside the groove plate 13, it will also drive the end of the blocking cloth 12 to move, causing the blocking cloth 12 to deform, and the blocking cloth 12 covers the groove plate 13 and the upper end of the telescopic plate 14, so that the mud cake splashes and may accumulate near the drill bit 2 or get stuck between the drill rod 1 and the well wall, increasing the risk of drill bit sticking and affecting the smooth progress of the measurement work. Therefore, in order to avoid this situation, when the telescopic plate 14 slides inside the groove plate 13, it will also drive the end of the blocking cloth 12 to move, causing the blocking cloth 12 to deform, and the blocking cloth 12 will cover the groove plate 13 and the upper end of the telescopic plate 14, so that the mud cake splashes and may accumulate near the drill bit 2 or get stuck between the drill rod 1 and the well wall, increasing the risk of drill bit sticking and affecting the smooth progress of the measurement work. When the mud cake splashes, it will only be concentrated in the cavity formed by the mounting plate 11, the groove plate 13, the telescopic plate 14, and the baffle 12, so that the mud cake can be concentrated, and then the motor 10 is used to drive the rotating rod 9 to rotate, so that the mud cake in the cavity falls into the collection box 3, thereby realizing the centralized collection of the mud cake after cleaning, thereby avoiding the mud cake splashing when the blade 15 scrapes the mud cake and accumulating near the drill bit 2 or getting stuck between the drill rod 1 and the well wall, increasing the risk of drilling and affecting the smooth progress of the measurement work;Furthermore, although the mounting plate 11, the groove plate 13, the telescopic plate 14 and the blocking cloth 12 can be used to block the splashing mud cake, since the blocking cloth 12 has a certain elasticity, the splashing mud cake is more likely to adhere to the surface of the blocking cloth 12. When the mud cake falls from the blocking cloth 12 into the collecting box 3, the mud cake may not be able to fall due to its strong adhesion, resulting in part of the mud cake remaining on the surface of the blocking cloth 12, thereby affecting the subsequent use of the blocking cloth 12. The mud cake may also accumulate at the blocking cloth 12, causing the mud cake to overflow, which again affects the drill rod 1 and the drill bit 2. Therefore, in order to avoid this situation, when the mud cake falls from between the blocking cloths 12, the motor 3 24 can be used to drive the crank 23 to rotate, so that the slider 22 makes a circular motion. At the same time, the slider 22 is moved on the T-bar 21. The vibration rod 16 can make a reciprocating motion by sliding in the slide groove of the vibration rod 16. The impact of the vibration rod 16 on the blocking cloth 12 can make the mud cake attached to the surface of the blocking cloth 12 fall off, thereby promoting the falling of the mud cake, thereby avoiding the situation that when the mud cake falls from the blocking cloth 12 into the collection box 3, it cannot fall due to the strong adhesion of the mud cake, resulting in part of the mud cake always remaining on the surface of the blocking cloth 12, thereby affecting the subsequent use effect of the blocking cloth 12. When the box door 7 is closed, the electromagnetic wave resistivity measurement module 5 is covered by the shell 6 and the box door 7, thereby avoiding the situation that foreign objects such as gravel hit the electromagnetic wave resistivity measurement module 5 when the drill rod 1 and the drill bit 2 are in the borehole, causing damage to the electromagnetic wave resistivity measurement module 5, thereby improving safety. When the drill rod 1 is outside the borehole, the box door 7 can be opened to operate the electromagnetic wave resistivity measurement module 5. ;
