Detailed implementation manners

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0031] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0032] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] The following combines Figures 1 to 10 , to describe the embodiments of the present invention.

[0034] As Figure 1 and Figure 2As shown, according to an embodiment of the invention, an offshore drilling operation platform is provided, including: a platform frame, with a plurality of accommodation spaces arranged in sequence in the same direction, and a drilling station 4 and a propulsion system 7 station reserved on the platform frame; a template 9, laid on the top of the steel structure frame; pontoons 2, arranged in the accommodation spaces and fixedly connected to the platform frame, with an annular space and a counterweight space arranged inside the pontoons 2, and the annular space surrounding the outside of the counterweight space; a buoyancy adjustment assembly, arranged in the annular space; a counterweight device 102, arranged in the counterweight space. A drilling rig 5 is arranged at the drilling station 4; a propulsion system 7 is arranged at the propulsion system 7 station.

[0035] The platform frame is welded from high-strength steel, with extremely high strength and stability, and can withstand various forces generated during the drilling operation. The pontoons 2 are fixedly installed in the accommodation spaces of the platform frame through high-strength connectors, forming an organic whole with the platform frame. The annular space surrounds the outside of the counterweight space, enabling the pontoons 2 to provide buoyancy while also being able to adjust the balance and stability of the platform through the internal counterweight device 102 and the buoyancy adjustment assembly. The configuration device is arranged inside the annular space. When the annular space is damaged such as by water ingress, the safety of the configuration space can still be ensured, thereby increasing the overall safety of the platform.

[0036] The buoyancy adjustment assembly can adjust the buoyancy of the platform in real time according to the actual operation requirements of the platform and the changes in the water area environment. When the platform needs to increase or decrease buoyancy, the control system activates the buoyancy adjustment assembly, which can effectively respond to the changes in buoyancy requirements of the platform at different operation stages and in different water area environments, ensuring that the platform is always in the best buoyancy state and improving the operation efficiency and safety of the platform.

[0037] During the drilling operation of the platform, due to factors such as the operation of the drilling rig 5 and the telescoping of the drill pipe, the center of gravity of the platform will change. At this time, the counterweight device 102 can automatically adjust the position of the counterweight blocks according to the change in the center of gravity, so that the center of gravity of the platform returns to the best balance position again, ensuring that the platform always remains stable during the drilling process. In addition, when the platform is moving or encountering complex water area environments such as wind and waves, the counterweight device 102 can also improve the anti-overturning ability of the platform and enhance the stability of the platform by adjusting the position of the counterweight blocks, guaranteeing the smooth progress of the drilling operation.

[0038] The propulsion system 7 provides power for the movement and positioning of the platform on the water, enabling the platform to move flexibly to the designated position according to the needs of the drilling operation and maintaining a stable position during the operation.

[0039] The entire offshore drilling operation platform realizes functions such as stable floating, flexible movement, precise drilling, and safe operation through the organic combination of various parts such as the platform frame, pontoons 2, buoyancy adjustment components, counterweight devices 102, drilling rigs 5, and propulsion systems 7. This offshore drilling operation platform has broad application prospects in the fields of resource exploration, geological surveys, and engineering drilling in waters such as the ocean, lakes, and rivers, and can provide efficient, safe, and reliable equipment support for offshore drilling operations.

[0040] Specifically, as Figure 7 , Figure 8 and Figure 9 shown, the platform frame includes: a steel structure frame, including transverse steel bars 11, top-layer longitudinal steel bars, and bottom-layer longitudinal steel bars. A plurality of transverse steel bars 11 are connected to form a rectangular frame structure 1. Spacers 12 are provided on the transverse steel bars 11 at the top and bottom layers. The spacers 12 are sleeved outside the transverse steel bars 11. Along the length direction of the transverse steel bars 11, a plurality of spacers 12 are evenly distributed. The top-layer longitudinal steel bars and the bottom-layer longitudinal steel bars are respectively connected to the spacers 12 at corresponding positions, and accommodation spaces are separated.

[0041] The spacers 12 not only serve as connecting components between the transverse steel bars 11 and the longitudinal steel bars but also play a role in separating the internal space of the platform. By reasonably arranging the spacers 12, the platform frame is separated into multiple accommodation spaces. The transverse steel bars 11 are welded to the spacers 12; the top-layer longitudinal steel bars 6 of the platform are arranged at the top of the platform through the top-layer spacers 12, reserving drilling positions; the bottom-layer longitudinal steel bars 8 of the platform are arranged at the bottom of the platform through the spacers 12, reserving drilling positions.

[0042] The pontoons 2 are placed between the top and bottom layers of the platform through the gap between two top-layer longitudinal steel bars 6 of the platform.

[0043] As Figure 1 , Figure 4 and Figure 10 shown, it also includes guardrails 3, and the guardrails 3 are fixedly connected around the platform by bolts.

[0044] Furthermore, the buoyancy adjustment component includes: a buoyancy detection module adapted to detect the buoyancy of the pontoons 2; a water pump provided in the annular space; and a control module communicatively connected to the buoyancy detection module and the water pump respectively. The control module controls the water pump to drain or intake water according to the buoyancy data detected by the buoyancy detection module.

[0045] The buoyancy detection module is a pressure sensor that can convert the change in buoyancy into an electrical signal and transmit the data to the control module. Through the real-time monitoring of the buoyancy detection module, the platform operator can always understand the current buoyancy state of the platform. The water pump is connected to the water body outside the float 2 through a pipeline and can perform drainage or water intake operations according to the instructions of the control module. By means of the drainage or water intake operation of the water pump, the water volume in the annular space can be changed, thereby realizing the dynamic adjustment of the buoyancy of the float 2. For example, when the platform needs to reduce the buoyancy, the water pump pumps the external water body into the annular space; when the platform needs to increase the buoyancy, the water pump discharges the water in the annular space, so that the buoyancy of the float 2 reaches a new balance state with the weight of the platform. The control module is connected to the buoyancy detection module and the water pump respectively through communication lines, can receive the buoyancy data transmitted by the buoyancy detection module in real time, and precisely control the water pump according to the preset control algorithm. The control module can quickly calculate the magnitude of the buoyancy that needs to be adjusted based on the real-time buoyancy data provided by the buoyancy detection module, combined with the operation requirements and safety thresholds of the platform, and send corresponding instructions to the water pump to control the drainage or water intake operation of the water pump. For example, when the buoyancy detection module detects that the platform buoyancy is higher than the set safety threshold, the control module will immediately start the water pump to pump the external water body into the annular space to reduce the buoyancy of the float 2 until the buoyancy returns to the safe range; conversely, when the buoyancy is too small, the control module will control the water pump to drain water to increase the buoyancy of the float 2. In addition, the control module also has a fault diagnosis and alarm function, can monitor the working status of the water pump and the buoyancy detection module in real time, and once an abnormal situation is found, immediately issue an alarm and take corresponding protection measures to ensure the safe operation of the buoyancy adjustment system.

[0046] Through the collaborative work of the buoyancy detection module, the water pump and the control module, the buoyancy adjustment component can achieve precise and dynamic adjustment of the buoyancy of the float 2, which not only improves the adaptability and stability of the offshore drilling operation platform in complex water environments, but also greatly reduces the working intensity of the platform operator, and improves the operation efficiency and safety.

[0047] Furthermore, the buoyancy adjustment component further includes a liquid level sensor. The liquid level sensor is communicatively connected to the control module, and the control module controls the water pump to drain water or intake water according to the liquid level information detected by the liquid level sensor. The collaborative work of the liquid level sensor and the control module not only optimizes the buoyancy adjustment process, but also reduces the working intensity of the operator. In addition, the liquid level sensor and the control module can also be used in combination to judge whether the float 2 is damaged. For example, if the float 2 is damaged and water enters, the liquid level sensor detects the water level. When the water level exceeds the preset value, it indicates that danger is about to occur. At this time, the water pump can be started to drain water, thereby reducing the danger.

[0048] Further, as Figure 3As shown, the buoyancy adjustment assembly further includes an inflation and deflation module. The inflation and deflation module is disposed in the annular space and is communicatively connected to the control module. The control module controls the inflation or deflation of the inflation and deflation module according to the buoyancy data detected by the buoyancy detection module.

[0049] The inflation and deflation module can change the buoyancy state of the buoy 2 more quickly. The speed of gas filling and discharging is much higher than the suction speed of liquid. Therefore, in the case of rapid buoyancy adjustment, such as when the platform encounters sudden wind and waves or needs to quickly adjust its attitude, the inflation and deflation module can respond quickly to ensure the stability and safety of the platform. The coordinated work of the inflation and deflation module and the control module not only optimizes the buoyancy adjustment process but also reduces the energy consumption and maintenance cost of the platform.

[0050] Among them, as Figure 3 shown, the buoy 2 includes: an inner cylinder 22, which forms a counterweight space; an outer cylinder 21, which is sleeved inside the inner cylinder 22 and is connected to the inner cylinder 22 by connecting ribs 23, and an annular space is formed between the outer cylinder 21 and the inner cylinder 22.

[0051] The inner cylinder 22 and the outer cylinder 21 are concentrically arranged. The inner cylinder 22 can provide a counterweight space for installing the counterweight device 102. The shape of the inner cylinder 22 is usually cylindrical. The outer cylinder 21 is sleeved outside the inner cylinder 22 and is connected to the inner cylinder 22 by connecting ribs 23. An annular space can be formed between the outer cylinder 21 and the inner cylinder 22, which can increase the structural strength and protection of the inner cylinder 22. The connecting ribs 23 not only provide the structural connection between the inner and outer cylinders 21 but also enhance the overall strength and stability of the buoy 2.

[0052] Furthermore, as Figure 3 shown, the inflation and deflation module includes: an airbag 101, which is provided with a through hole for the connecting rib 23 to pass through, and the airbag 101 is attached to the inner wall of the outer cylinder 21; an air pump, which is communicatively connected to the control module. The airbag 101 is made of a high-strength and corrosion-resistant flexible material, which can withstand gas pressure while adapting to the shape of the annular space. The airbag 101 is provided with a through hole, and the size and position of the through hole are exactly matched with the connecting rib 23, allowing the connecting rib 23 to pass through the airbag 101, thus not affecting the structural connection between the inner cylinder 22 and the outer cylinder 21, ensuring the overall strength of the buoy 2 and providing enough installation space for the airbag 101. The close combination of the airbag 101 and the outer cylinder 21 and the efficient control of the air pump make the buoyancy adjustment process more flexible and efficient. The air pump inflates or deflates according to the instructions of the control module. When the buoyancy detection module detects that the buoyancy of the buoy 2 is lower than the set value, the control module will instruct the air pump to inflate the airbag 101 to increase the buoyancy of the buoy 2; conversely, when the buoyancy is too high, the control module will instruct the air pump to discharge the gas from the airbag 101 to reduce the buoyancy of the buoy 2.

[0053] Furthermore, the counterweight device 102 includes: a driving motor; a lead screw mechanism connected to the driving end of the driving motor; a guide rail extending in the longitudinal direction of the floating drum 2; a slider slidably connected to the guide rail, and the slider is connected to the nut of the lead screw mechanism; wherein, when the floating drum 2 tilts, the driving motor drives the slider to move along the guide rail. The counterweight device 102 ensures the platform to maintain a stable posture in a complex water environment by precisely controlling the position of the counterweight block. Especially when the floating drum 2 tilts, it can quickly adjust the center of gravity and restore the platform to a horizontal state. When the floating drum 2 tilts, an inclination sensor is installed on the platform frame, and the control module will calculate the position of the center of gravity that needs to be adjusted according to the inclination angle detected by the inclination sensor, and instruct the driving motor to start. The driving motor converts the rotational motion into a linear motion through the lead screw mechanism, pushes the slider to move along the guide rail, thereby changing the position of the counterweight block, adjusting the center of gravity of the platform, and restoring the platform to a horizontal state.

[0054] Further, as Figure 5 shown, the propulsion system 7 includes: a stainless steel connecting rod 72; a handle 71 provided at one end of the stainless steel connecting rod 72; a thruster provided at the other end of the stainless steel connecting rod 72; a positioning and adjusting device 73 including an adjusting box 734, and the adjusting box 734 is provided with a hanging ear 733; wherein, the adjusting box 734 is hung on the platform frame through the hanging ear 733, and is connected to the adjusting box 734 through an adjusting bolt 732 passing through the hanging ear 733.

[0055] The handle 71 integrates a control circuit and sensors, and can convert the instructions of the operator, such as direction and speed, into electrical signals and transmit them to the control system of the thruster 74. Therefore, the operator controls the direction and speed of the thruster 74 through the handle 71. The control system of the thruster 74 adjusts the rotational speed and direction of the propeller according to the received signals, thereby realizing the movement and positioning of the platform. The thruster 74 generates thrust through the rotation of the propeller and pushes the platform to move on the water surface. The operator can flexibly adjust the direction and speed of the thruster 74 through the handle 71 to realize the forward movement, backward movement, turning and positioning of the platform.

[0056] Among them, the adjusting bolt 732 passes through the gasket 731 and the hanging ear 733 in sequence and then enters the adjusting box 734. The combination of the hanging ear 733 and the adjusting bolt 732 enables the adjusting box 734 to adjust its position, so that the thruster 74 can be adjusted in multiple directions, ensuring that the thruster 74 can work at the best angle and position, and enabling the propulsion system 7 to adapt to different platform structures and operation requirements.

[0057] The handle 71 is also provided with a display for displaying parameter data, such as the magnitude of buoyancy, etc.

[0058] Furthermore, a sliding block is sleeved on the stainless - steel connecting rod 72. The sliding block is slidably connected to the inner wall of the adjusting box 734 in the axial direction of the stainless - steel connecting rod 72. On one side of the sliding block facing the adjusting bolt 732, there is a T - shaped groove. The screw rod of the adjusting bolt 732 has a tapered end, and the tapered end is in interference fit with the T - shaped groove.

[0059] The sliding block can be made of high - strength engineering plastic or aluminum alloy material, with good wear resistance and lightweight characteristics. The sliding block is internally provided with a through - hole matching the diameter of the stainless - steel connecting rod 72 to ensure that the sliding block can slide smoothly on the stainless - steel connecting rod 72. The inner wall of the adjusting box 734 is provided with a slide rail or a guiding groove, which matches the outer surface of the sliding block to ensure that the sliding block can slide smoothly in the axial direction of the stainless - steel connecting rod 72.

[0060] When it is necessary to adjust the angle or position of the thruster 74, the operator loosens the adjusting bolt 732 to separate the tapered end from the T - shaped groove. At this time, the sliding block can slide freely in the axial direction of the stainless - steel connecting rod 72, and the operator can move the sliding block to a suitable position according to the need. After the adjustment is completed, the operator tightens the adjusting bolt 732, and the tapered end gradually enters the T - shaped groove. Due to the design of the tapered end, a certain pressure will be generated during the process of tightening the bolt, making the tapered end form an interference fit with the T - shaped groove. This interference fit not only ensures the firm fixation of the sliding block on the stainless - steel connecting rod 72 but also can withstand various forces generated during the operation of the thruster 74.

[0061] The preparation method of the platform of the present invention is as follows:

[0062] S1, determine the number of required pontoons

[0063] According to the environment where the platform is to be built, determine the self - weight of the platform, external loads, and buoyancy received, and consider the corresponding safety factor in combination with the specifications.

[0064] The self - weight of the platform mainly includes the weight of pontoons, steel bars (steel pipes), wooden boards, guardrails, and the platform propulsion system; the external loads are mainly the weight of drilling rigs, drill pipes, mud circulation systems, tools, and personnel; the buoyancy is mainly provided by pontoons.

[0065] According to the safety regulations for water area exploration in the "Safety Standard for Geotechnical Engineering Investigation" (GB50585 - 2019), the safety factor of the total load capacity should be greater than 5; when exploring in non - navigable rivers, lakes, reservoirs, etc. with a flow velocity less than 1.0 m / s and a wave height less than 0.1 m, the safety factor of the total load capacity of the raft - type exploration platform to be built should be greater than 3.

[0066] Combined with different water areas, select the corresponding safety factor K.

[0067] The calculation formula for the safety factor K is K = F 浮 / G荷载 , where F_buoyancy is the upward buoyancy force of the buoy on the water; G_load is the sum of the self-weight of the platform and the external load.

[0068] Calculate the number of buoys N required to meet the load, N = KG_load / (ρ 水 gV), where ρ 水 is the density of water; g is the acceleration due to gravity; V is the volume of the buoy.

[0069] Considering the stability of the platform, if the calculated number of buoys is odd, the number of buoys needs to be increased to make it an even number.

[0070] S2, Determine the platform size

[0071] According to the calculated number of buoys 2, combined with the size of the buoy 2 and the layout position of the drilling rig 5, determine the spacing of the transverse steel bars, the length of the longitudinal steel bars 6 on the top layer of the platform, and the length of the longitudinal steel bars 8 on the bottom layer of the platform.

[0072] S3, Lay the longitudinal steel bars 8 on the bottom layer of the platform. Pass the steel bars with the calculated size through the sleeves on the transverse supports and lay out the bottom of the platform according to the layout principle. Increase the friction at both ends of the steel bars to prevent them from slipping out.

[0073] S4, Place the buoy 2 between two adjacent longitudinal steel bars 8 on the bottom layer of the platform according to the layout principle.

[0074] S5, Lay the longitudinal steel bars 6 on the top layer of the platform. Pass the steel bars with the calculated size through the sleeves on the transverse supports and lay out the top of the platform according to the layout principle. Increase the friction at both ends of the steel bars to prevent them from slipping out.

[0075] S6, The platform propulsion system should be far away from the guardrail entrance and exit. In addition, a remote control operation device can be added to the propulsion system to increase the safety of waterborne driving.

[0076] S7, Lay the wooden board 9 on top of the longitudinal steel bars 6 on the platform top layer, reserve the drilling positions, and at the same time the wooden board should be flat.

[0077] S8, Install the guardrail 3 around the platform and connect it to the wooden board 9 through the guardrail fixing bolts 10.

[0078] S9, Select a suitable position to launch the platform into the water, and at the same time drive the drilling rig 5 onto the platform.

[0079] S10, Use the propulsion system 7 to drive the platform to the predetermined drilling position.

[0080] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners.

[0081] For those of ordinary skill in the art, based on the above description, other different forms of changes or alterations can be made. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or alterations derived therefrom still fall within the protection scope of the present invention.
