The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The following is combined Figure 1 This invention describes a drilling system provided by an embodiment of the present invention. It should be understood that the following description is merely an illustrative embodiment of the present invention and does not constitute any particular limitation on the present invention.

[0024] An embodiment of this utility model provides a drilling rig system, such as... Figure 1 As shown, it includes: a derrick 100; a top drive structure 200 slidably connected to the derrick 100; and an electric lifting drive mechanism connected to the top drive structure 200 for driving the top drive structure 200 to move up and down along the derrick 100.

[0025] The drilling rig system provided by this utility model includes a derrick 100, a top drive structure 200, and an electric lifting drive mechanism. The top drive structure 200 is slidably connected to the derrick 100 and can move up and down along the derrick 100. The electric lifting drive mechanism is connected to the top drive structure 200 and drives the top drive structure 200 to move up and down along the derrick 100, thereby raising or lowering the drill string. With this structural arrangement, only one electric lifting drive mechanism is needed to drive the top drive structure 200 to move up or down, eliminating the need for additional counterweight structures, thus simplifying the drive mechanism's structure and saving space.

[0026] In one embodiment of the present invention, the drilling system further includes an electric rotary drive mechanism, which is connected to the top drive structure 200 and is used to drive the top drive structure 200 to rotate.

[0027] During operation, the electric rotary drive mechanism drives the top drive structure 200 to rotate, which in turn drives the drill bit to rotate for drilling operations.

[0028] In one embodiment of this utility model, the electric lifting drive mechanism includes an electric cylinder.

[0029] In another embodiment of this utility model, the electric rotary drive mechanism includes: a motor.

[0030] It should be noted that the above embodiments are merely illustrative examples of this utility model and do not constitute any limitation on this utility model. That is, the electric lifting drive mechanism includes, but is not limited to, an electric cylinder, and the electric rotary drive mechanism includes, but is not limited to, a motor.

[0031] In one embodiment of the present invention, the drilling rig system further includes: a derrick support base 300, which supports the derrick 100 by resting it on the ground.

[0032] Furthermore, in one embodiment of the present invention, the drilling rig system further includes: an operating platform base 400, which is disposed adjacent to the derrick support base 300; and an operating platform 500, which is connected to the operating platform base 400.

[0033] like Figure 1 As shown, in this embodiment, the derrick support base 300 and the operating platform base 400 are independent of each other and are arranged adjacent to each other. The derrick support base 300 supports and connects the derrick 100, and the operating platform base 400 connects the operating platform 500. Compared with the existing drilling rig system in which the derrick 100 and the operating platform 500 are set on the same support base, the derrick support base 300 has a more uniform stress distribution and can better transfer the main load of the derrick 100 to the ground.

[0034] In one embodiment of the present invention, the drilling rig system further includes an electric tilting drive mechanism, wherein the derrick 100 is rotatably connected to the derrick support base 300, and the electric tilting drive mechanism is connected to the derrick 100 for driving the derrick 100 to tilt.

[0035] For example, a hinge seat is provided on the derrick support base 300, and the derrick 100 is connected to the hinge seat on the derrick support base 300 via a hinge shaft. The derrick 100 can be tilted relative to the derrick support base 300 to be erected or lowered. An electric tilting drive mechanism is installed between the derrick 100 and the derrick support base 300. The electric tilting drive mechanism can drive the derrick 100 to tilt and erect or tilt and lower. The electric tilting drive mechanism includes, but is not limited to, an electric cylinder.

[0036] In one embodiment of the present invention, the derrick 100 includes a plurality of separate segments 110, which are sequentially spliced ​​together.

[0037] For example, the derrick 100 comprises three separate sections 110, which are sequentially spliced ​​together and fastened together with bolts or other fasteners. The bottommost section 110 is connected to a hinge seat on the derrick support base 300 via a hinge shaft. During operation, the three sections 110 are spliced ​​together to form the complete derrick 100; during transportation, the complete derrick 100 can be disassembled into the three sections 110 for easier transport. This not only increases the height of the derrick 100 but also reduces the difficulty of transporting it.

[0038] Because the derrick 100 is relatively tall, it can drill one standoff at a time, with each standoff consisting of two drill pipes joined together. Compared to existing drilling systems that drill one drill pipe at a time, this drilling system significantly improves work efficiency.

[0039] In one embodiment of this utility model, the drilling rig system further includes a pipe laying system 600, which is arranged adjacent to the operating platform 500. The pipe laying system 600 is a key subsystem of the drilling rig system, responsible for the automated or semi-automated handling, arrangement, coupling, and storage of drill pipes, casing, and other tubing strings, thereby improving drilling efficiency and reducing the risks of manual operation. During the pipe laying process, the tubing string is first supplied: the catwalk grabs the tubing string from the pipe rack and pushes it to the drilling platform. Then, wellhead coupling is performed: the robotic arm aligns the tubing string with the wellhead drill string, and the steel driller 700 completes the coupling. Subsequently, drilling extension is performed: the top drive drives the newly connected tubing string to continue drilling. Finally, uncoupling and storage are performed: during tripping, the operation is reversed, and the tubing string is disassembled and returned to the pipe rack.

[0040] In another embodiment of the present invention, the drilling system further includes an iron drill 700, which is disposed on the operating platform 500 and located between the pipe laying system 600 and the derrick 100.

[0041] The Iron Drill 700 is a key piece of equipment in drilling rig systems used to automate the connection (coupling) and disconnection (uncoupling) of drill rods / casings, replacing traditional manual tongs operations, significantly improving efficiency and reducing safety risks.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
