[0028] like Figure 1 and Figure 3As shown, the drilling tool transfer device includes a cloud beam 6, a sliding shoe mechanism 1 and an inner stopper mechanism 3. The upper part of the cloud beam 6 is provided with a limit groove extending along its own length direction. The sliding shoe mechanism 1 is arranged on the cloud beam 6. The sliding shoe mechanism 1 is used to drive multiple pipes in the limit groove to move along the length direction of the cloud beam 6. The side wall of the limit groove is provided with a mounting hole, and the inner stopper mechanism 3 is arranged in the mounting hole. The inner stopper mechanism 3 is suitable for switching between an extended state and a retracted state; in the extended state, the inner stopper mechanism 3 is used to limit the pipe so that the first pipe entering the limit groove is at the center of the limit groove; in the retracted state, the inner stopper mechanism 3 is retracted into the cloud beam 6.

[0029] The drilling tool transfer device provided by the present invention is equipped with an internal retaining rod mechanism 3 on the side wall of the limit groove. The internal retaining rod mechanism 3 is used to limit the pipe string so that the first pipe string entering the limit groove is located in the center of the limit groove, and multiple pipe strings are sequentially and side by side and stay on one side wall of the limit groove; when the first pipe string is pushed to the wellhead, the second pipe string will slide downward under the action of gravity and be located in the center of the limit groove. Therefore, there is no need to set up a pipe string separation mechanism, which reduces the steps when drilling, makes the operation more convenient, simplifies the structure, reduces the failure points, and has higher stability.

[0030] In one embodiment of the present invention, the cloud beam 6 provides an installation foundation for the sliding shoe mechanism 1, the inner stopper mechanism 3 and other mechanisms, and the intermediate basic frame of the cloud beam 6 serves as the foundation of the entire drilling tool transfer device. The limit groove of the cloud beam 6 is used to accommodate the pipe string. In this embodiment, the cross-section of the limit groove is V-shaped. Of course, the cross-sectional shape of the limit groove is not limited to this, and is determined according to actual needs.

[0031] In one embodiment of the present invention, Figure 1 As shown, the drilling tool transfer device includes a plurality of inner blocking rod mechanisms 3, which are symmetrically arranged on the two side walls of the limit slot. During operation, the inner blocking rod mechanisms 3 on the same side wall of the limit slot are simultaneously in an extended state or in a retracted state.

[0032] In one embodiment of the present invention, Figure 1 As shown, the drilling tool transfer device includes four inner stopper mechanisms 3, wherein two inner stopper mechanisms 3 are arranged on one side wall of the limiting groove, and two inner stopper mechanisms 3 are arranged on the other side wall of the limiting groove. When the pipe string rolls into the limiting groove from one side of the limiting groove, the inner stopper mechanism 3 on the other side of the limiting groove is in an extended state to limit the pipe string.

[0033] In one embodiment of the present invention, Figure 3As shown, the inner stopper mechanism 3 includes an inner stopper 31 and a first driving member. The inner stopper 31 is a strip structure or a sheet structure. The inner stopper 31 is hinged to the cloud beam 6 through a first pin shaft. The inner stopper 31 is suitable for switching between an extended state and a retracted state. In the extended state, the inner stopper 31 extends from the mounting hole and is in a vertical state, thereby limiting the position of the pipe column. In the retracted state, the inner stopper 31 enters the interior of the cloud beam 6 through the mounting hole.

[0034] The first driving member is hinged to the inner stop rod 31 and the cloud beam 6, and the first driving member is used to drive the inner stop rod 31 to rotate around the first pin shaft, so that the inner stop rod 31 switches between the extended state and the retracted state. Specifically, the first driving member is a stop rod driving cylinder, the piston rod of the stop rod driving cylinder is hinged to the inner stop rod 31, and the cylinder body of the stop rod driving cylinder is hinged to the cloud beam 6. The inner stop rod 31 rotates around the first pin shaft through the extension and retraction of the stop rod driving cylinder. When the inner stop rod 31 is extended, it can ensure that the first pipe column that rolls into the limit groove remains in the center of the limit groove even under the impact of the next two pipe columns, so as to facilitate the subsequent operation of the rod feeding mechanism 2.

[0035] In one embodiment of the present invention, Figure 2 As shown, the sliding shoe mechanism 1 includes a supporting sliding shoe 11, a guiding sliding shoe 12, a conveying pipe support plate 121 and a first driving assembly.

All components of the sliding shoe mechanism 1 are integrated on the supporting sliding shoe 11. The bottom of the supporting sliding shoe 11 is provided with a first roller 13 that is slidably matched with the side wall of the limiting groove. Specifically, four first rollers 13 are arranged at the bottom of the supporting sliding shoe 11, two of which are arranged at one side of the bottom of the supporting sliding shoe 11, and the remaining two first rollers 13 are arranged at the other side of the bottom of the supporting sliding shoe 11.

[0036] The guide slide shoe 12 is disposed on the support slide shoe 11, and the guide slide shoe 12 is welded or bolted to the support slide shoe 11. A first slide shoe avoidance groove is disposed at the bottom of the guide slide shoe 12, and the first slide shoe avoidance groove is used to allow the driving rod 222 to pass through the bottom of the guide slide shoe 12 and the support slide shoe 11, and the width of the first slide shoe avoidance groove is greater than the thickness of the driving rod 222, ensuring that the driving rod 222 can freely pass through the first slide shoe avoidance groove.

[0037] The conveying pipe support plate 121 is arranged on the guide sliding shoe 12, specifically, the conveying pipe support plate 121 is arranged at the bottom of the guide sliding shoe 12, and the conveying pipe support plate 121 is used to receive and accommodate the pipe column coupling to prevent the pipe column thread from being damaged when the pipe column moves forward and backward. The conveying pipe support plate 121 is arranged along the length direction of the cloud beam 6, and the conveying pipe support plate 121 is provided with a second sliding shoe avoidance groove 122 along its own length direction, and the position of the second sliding shoe avoidance groove 122 corresponds to the position of the first sliding shoe avoidance groove. Specifically, two conveying pipe support plates 121 are arranged, and the two conveying pipe support plates 121 are arranged at intervals along the width direction of the cloud beam 6, and the second sliding shoe avoidance groove 122 is formed between the two conveying pipe support plates 121, and the center line of the second sliding shoe avoidance groove 122 is the same straight line as the center line of the first sliding shoe avoidance groove.

[0038] The first driving component is arranged inside the cloud beam 6 and connected to the supporting sliding shoe 11 . The first driving component is used to drive the supporting sliding shoe 11 to move along the length direction of the cloud beam 6 .

[0039] In a preferred embodiment of the present invention, a guide slope is provided at one end of the delivery pipe support plate 121 away from the support shoe 11, and the guide slope is located on the side where the two delivery pipe support plates 121 are close to each other, so that a triangular gap is formed between the two delivery pipe support plates 121, and the width of the triangular gap gradually decreases in the direction close to the support shoe 11. The two guide slopes can guide the pipe column, so that the pipe column can easily enter the upper part of the two delivery pipe support plates 121.

[0040] In one embodiment of the present invention, Figure 2 As shown, two groups of first drive assemblies are provided, and the two groups of first drive assemblies are arranged at intervals along the width direction of the cloud beam 6. The first drive assembly includes a chain 16 and a sprocket transmission device 15. The chain 16 is rotatably arranged inside the cloud beam 6, and the chain 16 is connected to the support slide shoe 11. Specifically, the chain 16 has two connecting ends, and fixed side plates 14 are arranged on both sides of the support slide shoe 11. The fixed side plates 14 are connected to the support slide shoe 11 by bolts. The two connecting ends of the chain 16 are connected to the same fixed side plate 14 after passing through the sprocket transmission device 15. The sprocket transmission device 15 is arranged inside the cloud beam 6, and the sprocket transmission device 15 is engaged with the chain 16. The sprocket transmission device 15 is used to drive the chain 16 to reciprocate to drive the support slide shoe 11 to move along the length direction of the cloud beam 6. When the sprocket transmission device 15 drives the chain 16 to reciprocate, the chain 16 drives the support slide shoe 11 to reciprocate along the length direction of the cloud beam 6.

[0041] It should be noted that the specific structure of the first driving assembly is not limited to the combination of the chain 16 and the sprocket transmission device 15, and may also be a cylinder, an electric push rod or other linear driving mechanisms.

[0042] In one embodiment of the present invention, Figure 4 As shown, the drilling tool transfer device also includes a rod delivery mechanism 2, which includes a linear drive assembly 23, a rod delivery track 211 and a rod delivery trolley 22.

The cross section of the delivery rod track 211 is U-shaped or C-shaped, and the delivery rod trolley 22 is clamped between the two delivery rod tracks 211.

[0043] In a specific embodiment of the present invention, the linear drive component 23 is a rod-sending cylinder, which is arranged along the length direction of the cloud beam 6. The telescopic rod of the rod-sending cylinder is hinged to the trolley body 221, and the cylinder body of the rod-sending cylinder is hinged to the cloud beam 6.

[0045] A limit plate 2211 is provided on the upper part of the trolley body 221. The limit plate 2211 is vertically provided, and the limit plate 2211 is welded or bolted to the trolley body 221. One end of the tension spring 224 is connected to the trolley body 221. Preferably, two tension springs 224 are provided, and the two tension springs 224 are located on both sides of the limit plate 2211, and one end of the tension spring 224 is hooked and connected to the trolley body 221. By providing two tension springs 224, the force of the driving rod 222 can be balanced, thereby enhancing the stability of the driving rod 222.

[0053] The present invention further provides a drilling tool transfer method, which is based on the drilling tool transfer device described in any one of the above embodiments, and the drilling tool transfer method comprises: Step S100, control the inner stop rod mechanism 3 to be in an extended state, and roll the first pipe column into the limiting groove from the side opposite to the inner stop rod mechanism 3, and limit the pipe column by the inner stop rod mechanism 3 so that the first pipe column is in the center of the limiting groove; then roll in multiple pipe columns in sequence, so that the multiple pipe columns stay in a row on one side wall of the limiting groove; Step S200, controlling the outer stop rod mechanism 4 to rise, and controlling the sliding shoe mechanism 1 to move toward the trolley body 221, so that the supporting sliding shoe 11 abuts against the pipe column; Step S300, when the cloud beam 6 rises to a predetermined position, the sliding shoe mechanism 1 is controlled to move to a standby position of the trolley body 221; Step S400, controlling the trolley body 221 to move away from the standby position so that the driving rod 222 is in an upright state, and pushing the pipe string in the center of the limiting groove to the wellhead through the driving rod 222; Step S500, when the elevator is stuck on the coupling of the pipe string, the trolley body 221 is controlled to move to the standby position so that the driving rod 222 is in a retracted state; Step S600, repeat the above steps in sequence until the pipe column in the limiting groove is pushed out.

[0054] By repeating the above steps, the second and third pipe strings in the limit groove can be pushed. The above steps are the process of drilling up, and the drilling process is the reverse process of drilling up. The difference is that the rod feeding mechanism 2 does not need to participate. After the first pipe string is placed in the center of the limit groove, the second and third pipe strings are respectively drawn into the cloud beam 6 along both sides of the first pipe string. After the cloud beam 6 falls to the horizontal, the push rod 51 rises, and the three pipe strings are pushed to the base at the same time, and the drilling operation is completed.
