Description

TECHNICAL FIELD

[0001] The present application relates to a land used oil drilling platform, in particular to a mobile base structure of an oil drilling platform which can be set up and moved. BACKGROUND

[0002] Oil is a fluid mineral buried deep in the ground. Initially, people call the oil-like liquid mineral produced in nature oil, call the combustible gas natural gas, and call the solid combustible oil-like mineral asphalt. With the in-depth study of these minerals, it is realized that they are all hydrocarbon compounds in composition and are related in origin, so they are collectively called oil. The role of oil in the national economy Oil is an important energy source. Compared with coal, it has the advantages of high energy density (the combustion heat of equal weight of oil is 50% higher than that of standard coal), convenient transportation and storage, and less air pollution after combustion. Fuel oil refined from oil is the main fuel for transportation tools, power station boilers, metallurgical industry and various kilns in building material industry. Liquefied gas and pipeline gas made of oil are high-quality fuels for urban residents. Aircraft, tanks, warships, rockets and other spacecraft also consume a large amount of oil fuel. Therefore, many countries have listed oil as a strategic material.

[0003] In the existing oil exploration and exploitation, whether on land or in the ocean, it is necessary to realize it through a drilling platform, and the drilling platform used on land is generally based on a wellbore, a base plate is built on the surrounding base frame to form a base platform, and a fence, power equipment, monitoring equipment, oil exploration or exploitation equipment and other auxiliary related facilities are arranged on the base platform;

[0004] Because various equipment needs to be carried, the drilling platform itself will inevitably be high and large in size, and a large number of hoisting equipment and various auxiliary machinery need to be used when building. If there is a certain number of wellbores in an area, drilling platforms need to be built at each wellbore, and it can be imagined that the engineering quantity is very large, and a large amount of manpower is needed to realize the above engineering quantity. More importantly, the traditional structure of the drilling platform is a fixed platform after being built, and once the wellbore at the platform does not need to be explored or exploited, it needs to be removed. In the exploration and exploitation of a single wellbore, the platform needs to be built and removed on site, which is large in engineering quantity and long in time, and the number of various equipment and human resources needed will inevitably be large. At the same time, a large amount of construction and removal work is easy to cause safety accidents. How to design a drilling platform that can be quickly expanded and transported to reduce the construction equipment during installation and removal is one of the problems that practitioners in the field need to solve.

[0020] By the above scheme, the present application has at least the following advantages:

[0021] Compared with the prior art design of the land oil drilling platform, the technical scheme disclosed by the present application respectively provides a drilling platform base member and a base moving member;

[0022] Firstly, the drilling platform base member itself can realize two states of standing and lying down. When the drilling platform base member is in the standing state, the connecting piece, keel frame, winch frame, rotary table beam, operation table and stand pipe head table and the like structures thereof can be used to install and set the power equipment, monitoring equipment and other auxiliary related facilities required for oil exploration or exploitation. After the wellhead corresponding to the drilling platform base member completes the work task, only the facilities installed on the drilling platform base member need to be removed, and then the drilling platform base member can be changed to the lying down state. The technical scheme of the present application directly designs the drilling platform base member as a modular structure which can quickly change the use posture, so as to facilitate quick use and quick removal. Unlike the prior art, the drilling platform does not need to be disassembled into multiple scattered parts, and needs to be gradually installed and disassembled as a whole when needed. This greatly saves the construction time and improves the work efficiency.

[0023] Further, the base moving member can be used to cooperate with the transfer and movement of the drilling platform base member. In actual use, tracks can be laid at multiple wellheads of an oil field, and the base moving member can be transferred and moved between the multiple wellheads by using the tracks. When the drilling platform base member needs to be transferred, it only needs to be adjusted to the lying down state, and then can be reliably fixed on the base moving member in cooperation with the base moving member. At this time, the base moving member can be used to transfer and move the drilling platform base member between the multiple wellheads. When needed, the drilling platform base member is separated from the base moving member and adjusted to the appropriate working position in the lying down state, and then the posture of the drilling platform base member is changed to the standing state, so as to explore or exploit the required wellhead.

[0024] In summary, the technical scheme of the present application can realize the quick setting and removal of the drilling platform base member under the condition of ensuring the normal work of exploration or exploitation, and transfer the drilling platform base member between multiple wellheads by the base moving member, so as to greatly improve the exploration or exploitation efficiency of the whole oil field, reduce the engineering quantity, shorten the erection and removal time of the platform, and greatly reduce the required number of various equipment and human resources. After a large amount of construction and removal work is reduced, the probability of accidents can also be greatly reduced.

[0041] The base moving member 2 includes a vehicle body 12 and an upper frame 13, and the upper frame 13 is detachably and fixedly arranged at the rear end of the vehicle body 12, and the drilling platform base member 1 in the laid-down state can reach above the vehicle body 12 through the upper frame 13 and be fixed, and the drilling platform base member 1 in the laid-down state can be moved through the base moving member 2.

[0042] The upper frame 13 can play a transition role, and the height of the vehicle body 12 is higher than that of the base 3 on the ground, so that the upper frame 13 can help the drilling platform base member 1 to reach the vehicle body 12 or slide down from the vehicle body 12, so as to facilitate the cooperation of the drilling platform base member 1 and the base moving member 2 and also play a role of protecting the drilling platform base member 1.

[0043] Preferably, each base 3 includes a base transverse plate 14 and base side plates 15 on both sides of the base transverse plate 14, and a ramp block 16 and a towing protection block 17 are detachably and fixedly arranged at the front and rear ends of each base 3 through bolts, the ramp block 16 can cooperate with the upper frame 13 to facilitate the drilling platform base member 1 in the laid-down state to reach the vehicle body 12 through the upper frame 13, and the towing protection block 17 can protect the rear end of the base 3.

[0044] The whole drilling platform base member 1 is supported and fixed by the two bases 3, but the heights of the base 3 and the vehicle body 12 are not consistent, so that the front end of the base 3 can be lifted (i.e. the front end of the whole drilling platform base member 1 is lifted) through the cooperation of the ramp block 16 and the upper frame 13 (inclined surface and inclined surface), and the upper frame 13 reaches the vehicle body 12 through the inclined surface, and when the front end of the base 3 is lifted, the rear end can be in contact with the ground through the towing protection block 17, and the circular arc structure of the towing protection block 17 can also facilitate the towing movement.

[0046] The wedge block 18 has an inclined surface capable of cooperating with the upper frame 13, facilitating the position adjustment and protection of the base 3 when the drilling platform base member 1 reaches the vehicle body 12 from the ground or returns to the ground from the vehicle body 12, and the contact block 20 also has the same protection effect;

[0047] When the drilling platform base member 1 reaches the vehicle body 12 or returns to the ground, the protection purpose is completed, and then the uphill block 16 and the drag protection block 17 can be immediately disassembled, facilitating subsequent operation.

[0049] The winch device 22 can apply force to pull the drilling platform base member 1 on the ground, the winding flexible member (steel wire rope, chain, etc.) of the winch device 22 can be wound and fixed on the force rod 25 and the limiting rod 26 to play a connecting role, so that the winch device 22 can apply force to pull or protect when the drilling platform base member 1 reaches the vehicle body 12 or returns to the ground;

[0050] When the drilling platform base member 1 needs to reach the ground and cooperate with the corresponding wellhead, the winch device can also be arranged at the wellhead, and the two sets of winch devices jointly act to help the drilling platform base member 1 leave the vehicle body 12 and reach the wellhead position.

[0051] Preferably, the upper frame 13 comprises two oppositely arranged ramp plates 27, and a plurality of rolling shafts 28 are uniformly arranged between the two ramp plates 27 from low to high and are matched with the drilling platform base member 1. Each rolling shaft 28 is arranged between the two ramp plates 27, and the plurality of uniformly arranged rolling shafts 28 form a sliding matching surface matched with the drilling platform base member 1 in the laid-down state. The rolling shaft 28 at the end of the upper frame 13 towards the vehicle body 12 is higher than the rolling shaft 28 at the end of the upper frame 13 towards the drilling platform base member 1, that is, the sliding matching surface is inclined. Each ramp plate 27 is detachably fixed at the rear end of the vehicle body 12 by bolts.

[0052] Through the sliding matching surface, the upper frame 13 can help the drilling platform base member 1 to reach the vehicle body 12 or return to the ground. The plurality of rolling shafts 28 can reduce the resistance during passing, which is conducive to the smooth passing of the base 3 and can also reduce the wear of the base 3 itself. The upper frame 13 itself can be removed from the vehicle body 12, so that when the vehicle body 12 needs to run on the track after use, it can be quickly removed.

[0053] Preferably, an operating platform 29 is arranged above the vehicle body 12, and two sets of oppositely arranged pressure limiting tables 31 are arranged on the vehicle body 12 by shock-absorbing devices 30.

[0054] The operating platform 29 is relatively a whole planar structure, and the operating personnel can perform reinforcing or disassembling work on the operating platform 29, such as the installation and disassembly process of the ramp block 16 and the towing protection block 17 and the connection process of the winding flexible member (steel wire rope, chain, etc.) and the force rod 25 and the limiting rod 26 of the winch device 22. Further, the two bases 3 of the drilling platform base member 1 can be supported by the two sets of pressure limiting tables 31 respectively, and the two sets of pressure limiting tables 31 can limit the base 3, ensuring that the whole drilling platform base member 1 is reliably fixed on the vehicle body 12. Since the pressure limiting tables 31 and the vehicle body 12 have shock-absorbing devices 30 therebetween, the pressure limiting tables 31 can also buffer and protect the vehicle body 12 and the drilling platform base member 1 respectively;

[0055] Further, if the drilling platform base member 1 is more convenient to move forward and backward on the pressure limiting platform 31, a roller structure can be added to the pressure limiting platform 31, so that the resistance of the drilling platform base member 1 when moving is greatly reduced, and the fixing of the drilling platform base member 1 on the vehicle body 12 can be realized through the winch device 22, and at the same time, a detachable locking member can be added to the pressure limiting platform 31 through bolts and the like, which can better ensure that the drilling platform base member 1 is fixed on the vehicle body 12.

[0056] The two sides of the vehicle body 12 are provided with position adjusting members 32 cooperating with the base 3 at the operation platform 29, and the position adjusting members 32 can adjust the posture of the drilling platform base member 1 to reach or leave the vehicle body 12 by lifting or pressing the base 3.

[0057] When the drilling platform base member 1 reaches the vehicle body 12, due to the action of the upper frame 13, the front end of the drilling platform base member 1 is inevitably raised and has a certain distance from the operation platform 29, at this time, the position adjusting member 32 can press down the front end of the drilling platform base member 1, help the front end of the two bases 3 of the drilling platform base member 1 to fully contact the pressure limiting platform 31, and reduce the impact force brought by the contact, and protect the drilling platform base member 1 and the vehicle body 12;

[0058] When the drilling platform base member 1 leaves the vehicle body 12, the front end of the drilling platform base member 1 can be lifted by the position adjusting member 32, helping the rear end of the two bases 3 to fully contact the sliding surface while reducing the impact force brought by the contact, and protecting the drilling platform base member 1 and the upper frame 13.

[0059] Preferably, the width of the pressure limiting platform 31 is greater than the width of the base 3, and the pressure limiting platform 31 has a guide edge 33 on both sides.

[0060] Through the guide edge 33, the pressure limiting platform 31 can limit the two bases 3, so that the drilling platform base member 1 can move within a certain range;

[0061] In actual use, in order for the base 3 to be more convenient to reach the pressure limiting platform 31, a slope can be formed on the side of the pressure limiting platform 31 facing the upper frame 13.

[0062] Preferably, the position adjusting member 32 includes a sliding block one 34, a lifting cylinder 35 and a contact block 36, the sliding block one 34 is slidably arranged on the side of the vehicle body 12 through a screw block member, the lifting cylinder 35 is fixedly arranged on the sliding block one 34, and the contact block 36 is fixedly arranged on the driving end of the lifting cylinder 35. The position adjusting member 32 realizes lifting or pressing contact with the base 3 through the contact block 36.

[0063] The slider 34 can drive the lifting cylinder 35 to move forward and backward at the side of the vehicle body 12, so as to ensure that the lifting cylinder 35 reaches the required working position, and the lifting cylinder 35 can drive the contact block 36 to ascend or descend, so that the position adjusting member 32 can press the upper end surface of the base 3 or lift the lower end surface of the base 3 through the contact block 36, thereby helping the drilling platform base member 1 to adjust to a suitable posture, and facilitating the movement of the drilling platform base member 1.

[0064] In actual use, the screw rod and slider member can also be replaced by a hydraulic or pneumatic transmission mode, and the lifting cylinder 35 can also be replaced by a hydraulic transmission mode.

[0065] Preferably, the vehicle body 12 has a stepped surface 37 at the front end, and the winch device 22 is fixedly arranged on the stepped surface 37, that is, the height of the winch device 22 is higher than that of the operation platform 29.

[0066] When the winch device 22 is located at a relatively high position, the drilling platform base member 1 can be more conveniently dragged, and the movement posture of the drilling platform base member 1 can be better adjusted in cooperation with the position adjusting member 32, thereby facilitating operation and protection.

[0067] Preferably, the rear end of the vehicle body 12 has a mounting table 42, the upper vehicle frame 13 is detachably fixedly arranged on the mounting table 42 through bolts, the mounting table 42 is rotatably provided with an adjusting roller 43 at the upper end, and the top end of the adjusting roller 43 is respectively higher than the operation platform 29 and the roller 28 at the end of the upper vehicle frame 13 towards the vehicle body 12.

[0068] The adjusting roller 43 can serve as a fulcrum for the drilling platform base member 1, so as to facilitate adjustment of the posture of the drilling platform base member 1 when the drilling platform base member 1 approaches or leaves the vehicle body 12. Since the top end of the adjusting roller 43 is respectively higher than the operation platform 29 and the roller 28 at the end of the upper vehicle frame 13 towards the vehicle body 12, when the base 3 of the drilling platform base member 1 reaches the adjusting roller 43, only a small part of the lower end of the base 3 will be in contact with the adjusting roller 43. At this time, the posture of the drilling platform base member 1 can be adjusted through the position adjusting member 32, thereby reducing the difficulty of adjustment.
