Description

Technical Field

[0001] The invention relates to the technical field of well sinking simulation using a simulated drilling method, and in particular to a well sinking simulation device using a simulated drilling method. Background Art

[0002] Well drilling refers to the process of using drilling equipment and technology to drill from the ground into rock or other formations to form a wellbore of a certain depth and diameter. In existing drilling technology, due to the complex and changeable geological conditions, problems that may arise during the drilling process need to be predicted in advance. When simulating the drilling of the drill rod into the formation, the drill rod is usually used to drill into different formation modules. By observing the drilling of the drill rod in the formation module, simulation prediction is performed to facilitate the study and prediction of various situations that may be encountered during the drilling process. However, since the drill rod needs to be drilled into different formation modules separately during the simulation test, it is impossible to test the drilling of the drill rod under different geological conditions at the same time, resulting in low simulation efficiency.

[0003] Therefore, a well drilling simulation device has been developed which can simultaneously simulate the drilling conditions of a drill rod under different geological conditions and improve the simulation efficiency. Summary of the invention

[0004] In order to overcome the disadvantage that the drill rod needs to be drilled into different formation modules separately and the drilling conditions of the drill rod under different geological conditions cannot be tested simultaneously, resulting in low simulation efficiency, the present invention provides a well drilling simulation device that can simultaneously simulate the drilling conditions of the drill rod under different geological conditions and improve the simulation efficiency.

[0005] The technical solution of the present invention is: a well drilling simulation device simulating the drilling method, including a base, a connecting disk, a connecting shaft, a lantern frame, a drilling mechanism and a mold layer mechanism, a connecting disk is connected to the middle of the base, a connecting shaft is connected to the upper side of the connecting disk, a lantern frame is connected to the upper part of the connecting shaft, a drilling mechanism capable of drilling holes is provided on the lantern frame, and a mold layer mechanism capable of simulating a formation module is provided on the base.

[0006] Furthermore, the drilling mechanism includes an inner frame, a vertical frame, a motor, a hollow screw, a sliding sleeve, a rotating ring, an inner rotating edge rod and a drill bit. A plurality of inner frames are connected to the outer side of the upper part of the lantern frame, the inner frames are connected to the vertical frames, the upper sides of the vertical frames are connected to the motors, the motor output shafts are connected to the hollow screws, the outer sides of the hollow screws are threadedly connected to the sliding sleeves, the sliding sleeves are slidably connected to the adjacent vertical frames, the lower sides of the sliding sleeves are rotatably connected to the rotating rings, the inner sides of the hollow screws are slidably connected to the inner rotating edge rods, the inner rotating edge rods are connected to the adjacent rotating rings, and the lower sides of the inner rotating edge rods are threadedly connected to the drill bits.

[0007] Furthermore, the mold layer mechanism includes an inner rotating ring, an elastic rod, an outer slide, a first reset torsion spring, a sliding frame and a mineral layer box. The inner rotating ring is rotatably connected to the upper middle side of the base, and a plurality of elastic rods are connected to the inner rotating ring. The elastic rods are all connected to the outer slide, and the outer slide is slidably connected to the base. The outer slide is rotatably connected to the sliding frame, and the sliding frame is connected to the connected outer slide with a first reset torsion spring. The sliding frame is clamped with a mineral layer box, and the mineral layer box is rotated to adjust the mineral layer box to a suitable direction to drive the sliding frame to rotate, and the first reset torsion spring is deformed, so that the staff can fill different types of formation modules into the mineral layer box respectively. After filling, the mineral layer box is loosened, the first reset torsion spring is restored, the sliding frame is reset, and the mineral layer box is reset, and then the motor is started to drive the hollow screw to rotate and the inner rotating edge rod to rotate. At this time, the sliding outer sleeve slides downward, driving the rotating ring to slide downward, so that the inner rotating edge rod moves downward, and then the drill bit moves downward and rotates to drill into the formation module in the corresponding mineral layer box.

[0008] Furthermore, it also includes a wave ring, which is connected to the upper side of the middle part of the base, the wave ring is located outside the inner rotating ring, and the elastic rods are in contact with the wave ring.

[0009] Furthermore, it also includes a flap, and the upper part of the ore layer box is rotatably connected with the flap.

[0010] Furthermore, it also includes a vibration mechanism, which includes a fixed shifting frame, a guide rail and a sliding wave plate. The fixed shifting frame is connected to the outer side of the upper part of the sliding outer shell, and multiple guide rails are connected to the ore layer box. Multiple sliding wave plates are slidably connected to the guide rails. The position of the sliding wave plate on the guide rail is slidably adjusted. When the sliding outer shell moves downward, it drives the fixed shifting frame to move downward, so that the fixed shifting frame shifts the sliding wave plate, causing the sliding wave plate to vibrate.

[0011] Furthermore, it also includes a self-locking mechanism, which includes a middle plate, a limit frame, a long spring, a guide rod, a fixed frame and a short spring.

When the sliding sleeve moves downward, it drives the fixed frame to move downward, and the middle plate is pushed downward by the force of the long spring. The short spring is squeezed and contracted, so that the limit frame moves downward until it contacts the ore layer box, and then the sliding sleeve continues to move downward, the fixed frame moves downward on the guide rod, and the long spring is squeezed and contracted.

[0012] Furthermore, it also includes a clamping rod, and a plurality of clamping rods are connected to the lower side of the middle plate. When the limit frame moves downward, the clamping rods are driven to move downward, so that the clamping rods are clamped and matched with the elastic rods.

When the drill moves downward through the limit frame, it contacts the brushes on the folding plates.

[0014] Furthermore, it also includes a positioning mechanism, which includes a fixed plate, a second reset torsion spring and a clamping arm. The sliding frame is connected to multiple fixed plates, and the fixed plates are rotatably connected to the clamping arms. Multiple second reset torsion springs are connected between the clamping arms and the connected fixed plates. The clamping arms are clamped and matched with adjacent mineral layer boxes. When the mineral layer box is pushed onto the sliding frame, the clamping arm is rotated downward, and the second reset torsion spring is deformed. After the mineral layer box is pushed onto the sliding frame, the clamping arm is released, and the second reset torsion spring is restored, so that the clamping arm rotates and resets to clamp and match with the mineral layer box.

[0015] The beneficial effects are: 1. The present invention starts the motor to drive the hollow screw to rotate, and the inner rotating edge rod to rotate. At this time, the sliding outer sleeve slides downward, driving the rotating ring to slide downward, so that the inner rotating edge rod moves downward, and then the drill bit moves downward and rotates to drill into the formation module in the corresponding ore layer box, thereby achieving the effect of being able to simultaneously simulate the drilling conditions of the drill rod under different geological conditions and improving the simulation efficiency.

[0016] 2. The present invention adjusts the position of the sliding wave plate on the guide rail by sliding. When the sliding outer sleeve moves downward, the fixed shifting frame is driven to move downward, so that the fixed shifting frame shifts the sliding wave plate to vibrate the sliding wave plate, thereby achieving the effect of vibrating the ore layer box and increasing the density of the stratum module.

[0017] 3. The present invention drives the fixed frame to move downward while the sliding outer sleeve moves downward, and the middle plate is pushed downward by the force of the long spring. The short spring is squeezed and contracted, so that the limit frame moves downward until it contacts the ore layer box. When the limit frame moves downward, it drives the clamping rod to move downward, so that the clamping rod and the elastic rod are engaged with each other, thereby achieving the effect of being able to lock the ore layer box and the elastic rod to ensure that the ore layer box is located below the drill bit.

[0018] 4. The present invention achieves the effect of cleaning the drill bit and preventing impurities from adhering to the drill bit and affecting drilling by contacting the brush on the folding plate when the drill bit moves downward through the limit frame.

[0019] 5. When the ore layer box of the present invention is pushed onto the sliding frame, the clamping arm is rotated downward, and the second reset torsion spring is deformed. After the ore layer box is pushed onto the sliding frame, the clamping arm is released, and the second reset torsion spring is restored, so that the clamping arm rotates and resets to engage with the ore layer box, thereby achieving the effect of being able to position the ore layer box and preventing the ore layer box from moving.

DETAILED DESCRIPTION

[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] A well drilling simulation device, such as Figure 1-Figure 12 As shown, it includes a base 1, a connecting disk 2, a connecting shaft 3, a lantern frame 4, a drilling mechanism 5 and a mold layer mechanism 6. The connecting disk 2 is connected to the middle of the base 1, the connecting shaft 3 is connected to the upper side of the connecting disk 2, the upper part of the connecting shaft 3 is connected to the lantern frame 4, the lantern frame 4 is provided with a drilling mechanism 5, and the base 1 is provided with a mold layer mechanism 6.

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, the drilling mechanism 5 includes an inner frame 51, a vertical frame 52, a motor 53, a hollow screw 54, a sliding sleeve 55, a rotating ring 56, an inner rotating edge rod 57 and a drill bit 58. Six inner frames 51 are connected to the outer side of the upper part of the lantern frame 4. The inner frames 51 are connected to the vertical frames 52. The upper sides of the vertical frames 52 are connected to the motors 53. The output shafts of the motors 53 are connected to the hollow screws 54. The outer sides of the hollow screws 54 are threadedly connected to the sliding sleeves 55. The sliding sleeves 55 are slidably connected to the adjacent vertical frames 52. The lower sides of the sliding sleeves 55 are rotatably connected to the rotating rings 56. The inner sides of the hollow screws 54 are slidably connected to the inner rotating edge rods 57. The inner rotating edge rods 57 are connected to the adjacent rotating rings 56. The lower sides of the inner rotating edge rods 57 are threadedly connected to the drill bits 58.

[0036] like Figure 1 , Figure 5 and Figure 6 As shown, the mold layer mechanism 6 includes an inner rotating ring 61, a wave ring 62, an elastic rod 63, an outer slide 64, a first reset torsion spring 65, a sliding frame 66, a mineral layer box 67 and a flap 68. The inner rotating ring 61 is rotatably connected to the upper middle side of the base 1. Six elastic rods 63 are connected to the inner rotating ring 61. The wave ring 62 is connected to the upper middle side of the base 1. The wave ring 62 is located outside the inner rotating ring 61. The elastic rods 63 are in contact with the wave ring 62. The elastic rods 63 are connected to the outer slide 64. The outer slides 64 are slidably connected to the base 1. The outer slides 64 are rotatably connected to the sliding frames 66. The sliding frames 66 are connected to the outer slides 64 connected thereto with the first reset torsion spring 65. The sliding frames 66 are clamped with mineral layer boxes 67. The upper part of the mineral layer boxes 67 is rotatably connected to the flap 68.

[0037] When using the present invention, first place the base 1 in the simulated well drilling simulation area, then rotate and open the flip cover 68, rotate and adjust the ore layer box 67 to a suitable direction, drive the sliding frame 66 to rotate, and the first reset torsion spring 65 is deformed, so that the staff can fill different types of stratum modules into the ore layer box 67 respectively. After filling, loosen the ore layer box 67, and the first reset torsion spring 65 is restored to reset the sliding frame 66 and drive the ore layer box 67 to reset. Then start the motor 53 to drive the hollow screw 54 to rotate and the inner rotating edge rod 57 to rotate. At this time, the sliding sleeve 55 slides downward, driving the rotating ring 56 to slide downward, so that the inner rotating edge rod 57 moves downward, and then the drill bit 58 moves downward and rotates to drill into the corresponding ore layer box. In the formation module inside 67, it can simultaneously simulate the drilling conditions of the drill rod under different geological conditions and improve the simulation efficiency. During the simulation, different drill bits 58 can be replaced for simulation, or the inner rotating ring 61 can be rotated to drive the elastic rod 63 to rotate, so that the outer slide 64 moves, and the position of the ore layer box 67 is changed, so that the drill bit 58 can drill into different formation modules for testing, increase the test variables, and improve the test accuracy. When the elastic rod 63 rotates, it moves along the wave ring 62, and the elastic rod 63 is clamped by the groove of the wave ring 62 to ensure that the elastic rod 63 rotates to the specified position. After the drilling is completed, the hollow screw 54 is rotated in the opposite direction, so that the sliding sleeve 55 moves upward and resets.

[0038] like Figure 1 and Figure 7 As shown, a vibration mechanism 7 is also included, which includes a fixed frame 71, a guide rail 72 and a sliding wave plate 73. The upper outer side of the sliding sleeve 55 is connected to the fixed frame 71, and the ore layer box 67 is connected to two guide rails 72. Three sliding wave plates 73 are slidably connected to the guide rails 72.

[0039] By using the vibration mechanism 7 of the device, the ore layer box 67 can be vibrated, and the position of the sliding wave plate 73 on the guide rail 72 can be adjusted by sliding. When the sliding sleeve 55 moves downward, the fixed shifting frame 71 is driven to move downward, so that the fixed shifting frame 71 shifts the sliding wave plate 73, causing the sliding wave plate 73 to vibrate, thereby causing the ore layer box 67 to vibrate and increasing the density of the formation module.

[0040] like Figure 1 , Figure 8 , Fig. 9 and Fig.10As shown, a self-locking mechanism 8 is also included, and the self-locking mechanism 8 includes a middle plate 81, a limit frame 82, a long spring 83, a guide rod 84, a fixed frame 85, a clamping rod 86 and a short spring 87. The lower part of the connecting shaft 3 is slidably connected to the middle plate 81, the outer side of the middle plate 81 is connected to six limit frames 82, the upper side of the middle plate 81 is connected to six guide rods 84, the upper inner side of the sliding sleeve 55 is connected to the fixing frame 85, the fixing frame 85 is slidably connected to the adjacent guide rods 84, the long spring 83 is connected between the adjacent guide rods 84 of the fixing frame 85, the lower side of the middle plate 81 is connected to six clamping rods 86, and a short spring 87 is connected between the middle plate 81 and the connecting shaft 3.

[0041] The self-locking mechanism 8 of the device can be used to lock the ore layer box 67 and the elastic rod 63. When the sliding sleeve 55 moves downward, it drives the fixed frame 85 to move downward. The middle plate 81 is pushed downward by the force of the long spring 83, and the short spring 87 is squeezed and contracted, so that the limit frame 82 moves downward until it contacts the ore layer box 67. When the limit frame 82 moves downward, it drives the clamping rod 86 to move downward, so that the clamping rod 86 and the elastic rod 63 are engaged and matched. Then the sliding sleeve 55 continues to move downward, and the fixed frame 85 moves downward on the guide rod 84. The long spring 83 is squeezed and contracted. When the sliding sleeve 55 moves upward and resets, it drives the fixed frame 85 to move upward and reset, and the long spring 83 rebounds accordingly. The short spring 87 rebounds, so that the middle plate 81 is reset, thereby locking the ore layer box 67 and the elastic rod 63 to ensure that the ore layer box 67 is located below the drill bit 58.

[0042] like Figure 1 and Fig.11 As shown, a cleaning mechanism 9 is also included. The cleaning mechanism 9 includes a folding plate 91 and a brush 92. The upper side of the limiting frame 82 is connected to two folding plates 91, and the folding plates 91 are connected to the brush 92.

[0043] The cleaning mechanism 9 of the device can be used to clean the drill bit 58. When the drill bit 58 moves downward through the limit frame 82, it contacts the brush 92 on the folding plate 91, thereby cleaning the drill bit 58 and preventing impurities from adhering to the drill bit 58 and affecting drilling.

[0044] like Figure 1 and Fig.12 As shown, it also includes a positioning mechanism 10, which includes a fixed plate 101, a second reset torsion spring 102 and a clamping arm 103. Four fixed plates 101 are connected to the sliding frame 66, and the fixed plates 101 are rotatably connected to the clamping arms 103. The clamping arms 103 are connected to the connected fixed plates 101 with two second reset torsion springs 102, and the clamping arms 103 are clamped and matched with the adjacent mineral layer boxes 67.

[0045] By using the positioning mechanism 10 of the device, the ore layer box 67 can be positioned. When the ore layer box 67 is pushed onto the sliding frame 66, the clamping arm 103 is rotated downward, and the second reset torsion spring 102 is deformed. After the ore layer box 67 is pushed onto the sliding frame 66, the clamping arm 103 is released, and the second reset torsion spring 102 is restored, so that the clamping arm 103 rotates and resets to engage with the ore layer box 67, thereby positioning the ore layer box 67 and preventing the ore layer box 67 from moving.

[0046] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
