Simultaneously, the two symmetrically arranged inclined ladders form a two-way passageway, achieving personnel separation and avoiding congestion, while also providing a two-way escape route in emergency situations, significantly improving emergency escape efficiency and reducing congestion risks.

Description

Technical Field

[0001] This utility model relates to the field of oil and gas extraction equipment technology, and in particular to a new type of well workover drilling platform base that facilitates personnel access. Background Technology

[0002] In the oil and gas extraction industry, well workover operations are a core component for ensuring normal production of oil and gas wells and handling downhole faults. As a key infrastructure that supports workover equipment and provides a platform for personnel, the structural design of the workover rig base directly affects operational efficiency, personnel safety, and on-site space utilization. Currently, traditional workover rig bases in the industry have gradually revealed many technical pain points in practical applications due to issues such as the mismatch between deck height and personnel access needs, and the simplistic design of the support system. Therefore, a new type of workover rig base that facilitates personnel access is an innovative infrastructure designed for well workover operations in the oil and gas extraction industry, addressing the pain points of traditional rig bases such as inconvenience for personnel access, insufficient support stability, and low space utilization.

[0003] However, existing new well workover rig bases that facilitate personnel access have the following drawbacks: (1) The traditional well repair drilling platform base long inclined ladder needs to extend from the ground to the edge of the original deck at a height of 7m. Its horizontal projection will occupy the length of the deck of nearly 9m, which may make it difficult to place the pipes according to the classification and zoning principle. They can only be piled up around the inclined ladder, which is prone to problems such as pipe collision and corrosion. At the same time, when personnel move pipes and operate equipment on the deck, they need to go around the long inclined ladder, thereby increasing the ineffective walking distance. Especially in emergency situations, the long inclined ladder may become a traffic obstacle and delay the speed of emergency response. (2) Traditional well workover drilling platform bases mostly adopt a simplified support mode of bottom foundation, main column and upper deck. The support points are concentrated on 4-6 main columns, lacking auxiliary support points and local reinforcement support. This may result in extremely poor risk resistance of the support system. When a main column fails due to cracking of the welding joint or bending of the column, the remaining support points need to bear additional loads, which may trigger a domino effect, resulting in the upper deck tilting or even the entire structure collapsing.

[0004] Therefore, this utility model provides a new type of well workover drilling platform base that facilitates personnel getting on and off. Utility Model Content

[0005] (a) Technical problems to be solved The problem solved by the utility model is to provide a new type of well workover drilling platform base that is more practical and facilitates personnel to go up and down. It solves the problems mentioned in the background art, such as the inclined ladder extending from the ground to the edge of the original deck at a height of 7m, which may make it difficult to place pipes according to the principle of classification and zoning, and the lack of auxiliary support points and local reinforcement support of the base may lead to extremely poor risk resistance of the support system.

[0006] (II) Technical Solution To achieve the above objectives, this utility model is implemented through the following technical solution: a novel well workover drilling platform base that facilitates personnel access, comprising an initial deck, wherein a graded transfer assembly is provided at the top of the initial deck, and multiple support assemblies are provided at the bottom of the initial deck; The graded transfer assembly includes a support base fixedly connected to the top of the initial deck. Multiple support rods are fixedly connected to the surface of the support base. The top ends of the support rods are connected to a transition deck. The top ends of the multiple support rods are fixedly connected to the four corners of the bottom of the transition deck. Two symmetrically arranged inclined ladders are installed on the surface of the initial deck. Both inclined ladders extend to both sides of the transition deck. Two symmetrically arranged inclined ladders are provided on both sides of the initial deck. Both inclined ladders extend to the ground. The multiple support assembly includes support columns fixedly connected to the four corners of the bottom of the initial deck. The bottom of each support column is fixedly connected to a support plate. Two support diagonal rods are fixedly connected to both sides of the bottom of the initial deck. One end of each of the two support diagonal rods is connected to a support base. A reinforcing rod is connected between the two support diagonal rods.

[0007] Optionally, the top of the initial deck is fixedly connected with multiple auxiliary connecting rods, one end of which extends to and connects to the surface of the support rod, thereby strengthening the connection stiffness between the initial deck and the transition deck, dispersing the load transmitted by the transition deck and the inclined ladder, and preventing the support rod from deforming due to excessive local stress.

[0008] Optionally, handrails are fixedly connected to both sides of the two inclined ladders. The handrails are inclined to ensure the safety of people going up and down the inclined ladders, and to provide a grip for people to climb, preventing them from falling due to physical exhaustion or accidental shaking.

[0009] Optionally, multiple triangular support ribs are connected between the support column and the support plate. The triangular support ribs are arranged in a triangular shape to reinforce the connection node between the support column and the support plate. The geometric stability of the triangle is used to evenly distribute the vertical load of the support column onto the support plate, avoiding the load from being concentrated in a local area at the column base, and at the same time enhancing the shear resistance of the node.

[0010] Optionally, two reinforcing rods are connected between two adjacent support columns, and a supporting vertical rod is connected between the two reinforcing rods to improve the lateral stiffness between the support columns, resist the lateral impact of horizontal loads on the base, and prevent the support columns from tilting due to horizontal forces.

[0011] Optionally, the surfaces of the two inclined ladders are provided with treads, and the surfaces of the treads are provided with anti-slip textures to increase the friction of the inclined ladder treads and effectively prevent people from slipping when going up or down the inclined ladders.

[0012] (III) Beneficial Effects This utility model provides a novel well workover drilling platform base that facilitates personnel access, and has the following beneficial effects: 1. This new type of well-workover drilling platform base, which facilitates personnel access, breaks down the original 7-meter single climb into two short-distance climbs via a transition deck, greatly reducing personnel physical exertion. Especially when carrying tools or frequently climbing up and down, it effectively reduces fatigue and improves work efficiency. It can also serve as a temporary tool storage area and personnel transfer platform, avoiding the compression of the drilling platform deck's pipe and tool placement area and equipment operation area by traditional long inclined ladders. This optimizes the layout of the on-site work space, making the placement of pipes and tools more organized and the work flow smoother. At the same time, the two symmetrically arranged inclined ladders form a two-way passage, which not only separates personnel and avoids congestion, but also provides a two-way escape route in emergency situations, greatly improving emergency escape efficiency and reducing the risk of congestion.

[0013] 2. This new type of well-workover drilling platform base, which facilitates personnel access, increases the contact area with the ground through the combination of support columns and support plates. This evenly distributes the vertical loads of the initial deck and upper equipment to the ground foundation, preventing ground collapse due to excessive local pressure and ensuring the vertical stability of the base. Furthermore, the triangular stable structure formed by the support diagonal bars, reinforcing bars, and support base greatly enhances the base's resistance to horizontal forces. It can effectively resist the lateral impact of horizontal loads such as strong winds and equipment vibrations on the base, preventing the initial deck from shifting or overturning. The vertical and horizontal three-dimensional support network constructed by the reinforcing bars and support vertical bars between adjacent support columns further improves the overall rigidity and stability of the base.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figures 1 to 4 This utility model provides a technical solution: a novel well workover drilling platform base that facilitates personnel getting on and off, including an initial deck 1, a graded transfer assembly 2 on the top of the initial deck 1, and a multi-support assembly 3 on the bottom of the initial deck 1. The graded transfer assembly 2 includes a support base 201 fixedly connected to the top of the initial deck 1. The support base 201 provides a stable installation reference for the support rods 202 and distributes the load transmitted by the transition deck 203 and the inclined ladder 204. Multiple support rods 202 are fixedly connected to the surface of the support base 201. The top ends of the support rods 202 are all connected to the transition deck 203. The top ends of the multiple support rods 202 are fixedly connected to the four corners of the bottom of the transition deck 203. The support rods 202 are distributed in multiple positions at the four corners of the bottom of the transition deck 203, bearing the load of the transition deck 203. The vertical load of 3 is transferred to the support 201 to ensure the structural rigidity of the transition deck 203. Two symmetrically arranged inclined ladders 204 are installed on the surface of the initial deck 1. Both inclined ladders 204 extend to both sides of the transition deck 203. Two symmetrically arranged inclined ladders 204 are set on both sides of the initial deck 1. Both inclined ladders 204 extend to the ground. The inclined ladders 204 adopt a symmetrical dual-path design to achieve personnel separation and avoid crowding. The short ladder design improves climbing safety and can also serve as a two-way escape route in emergency situations. The multi-support assembly 3 includes support columns 301 fixedly connected to the four corners of the bottom of the initial deck 1. The support columns 301 bear the vertical transmission of all loads of the initial deck 1 and the upper part, providing stable vertical support for the initial deck 1 and preventing the initial deck 1 from settling or tilting due to excessive load. The bottom end of the support column 301 is fixedly connected to a support plate 302. Two support diagonal rods 303 are fixedly connected to both sides of the bottom of the initial deck 1. The support diagonal rods 303 utilize the principle of triangular stability to enhance the resistance of the bottom of the initial deck 1 to horizontal forces and resist the lateral impact of horizontal loads such as strong winds and equipment vibrations on the base. One end of the two support diagonal rods 303 is connected to a support base 304. A reinforcing rod 305 is connected between the two support diagonal rods 303. The reinforcing rod 305 provides lateral reinforcement to the support diagonal rod 303 system, preventing the support diagonal rods 303 from deforming due to horizontal forces and improving the overall rigidity of the support diagonal rod 303 system. Multiple auxiliary connecting rods 4 are fixedly connected to the top of the initial deck 1. One end of the auxiliary connecting rod 4 extends to the surface of the support rod 202 and is connected thereto, which strengthens the connection stiffness between the initial deck 1 and the transition deck 203, disperses the load transmitted by the transition deck 203 and the inclined ladder 204, and prevents the support rod 202 from deforming due to excessive local stress. Both sides of the two inclined ladders 204 are fixedly connected with handrails 5. The handrails 5 are set at an angle to ensure the safety of people going up and down the inclined ladders 204, and to provide a grip for people to climb and prevent them from falling due to physical exhaustion or accidental swaying. Multiple triangular support ribs 6 are connected between the support column 301 and the support plate 302. The triangular support ribs 6 are arranged in a triangle to reinforce the connection node between the support column 301 and the support plate 302. The geometric stability of the triangle is used to evenly distribute the vertical load of the support column 301 to the support plate 302, avoid the load from being concentrated in a local area at the column foot, and enhance the shear resistance of the node. Two reinforcing rods 7 are connected between two adjacent support columns 301, and a supporting vertical rod is connected between the two reinforcing rods 7 to improve the lateral stiffness between the support columns 301, resist the lateral impact of horizontal load on the base, and prevent the support columns 301 from tilting due to horizontal force. The surfaces of the two inclined ladders 204 are equipped with treads, and the surfaces of the treads are provided with anti-slip textures to increase the friction of the treads of the inclined ladders 204 and effectively prevent people from slipping when going up or down the inclined ladders 204.

[0018] In this invention, the working steps of the device are as follows: First step: First, the support base 201 is fixedly connected to the top of the initial deck 1 to provide a stable installation benchmark for the subsequent structure. Then, multiple support rods 202 are fixed on the surface of the support base 201, and the top ends of the support rods 202 are connected to the four corners of the bottom of the transition deck 203 to complete the suspended support installation of the transition deck 203. This effectively solves the problem that traditional well workover drilling platform bases do not have a transition deck 203 and personnel need to climb long inclined ladders 204 in one go. Subsequently, two symmetrical inclined ladders 204 are installed on the surface of the initial deck 1 and extended to both sides of the transition deck 203. At the same time, two symmetrical inclined ladders 204 are set on both sides of the initial deck 1 and extended to the ground, forming a segmented passageway from the ground to the initial deck 1 and the transition deck 203. The second step involves connecting the support columns 301 to the four corners of the bottom of the initial deck 1, and then connecting the support plate 302 to the support column 301, thus constructing the core vertical support system of the initial deck 1. Next, two support diagonal rods 303 are fixed on each side of the bottom of the initial deck 1, and one end of the two support diagonal rods 303 is connected to the support base 304. A reinforcing rod 305 is connected between the two support diagonal rods 303. Through the coordinated action of multiple structures, a three-dimensional support and reinforcement system is formed. Utilizing the principle of triangular stability, the horizontal force resistance of the bottom of the initial deck 1 is enhanced, effectively resisting the lateral impact of horizontal loads such as strong winds and equipment vibrations on the base, and preventing the initial deck 1 from shifting or overturning.
