A new type of fast moving drilling rig derrick base structure

A derrick and rapid technology, applied in the direction of drilling equipment, earthwork drilling, supporting devices, etc., can solve the problems of being unable to use in the desert environment, high center of gravity of the derrick, and low transportation efficiency, so as to reduce the construction amount of the well site and the transportation height The effect of low and high transfer efficiency

Problems solved by technology

[0002] At present, most of the towed and transported oilfield derricks and bases are transported separately, such as figure 1 , 2 , due to the high center of gravity of the derrick, the reliability is poor when it is moved to the trailer device before moving, and the derrick and the base must be assembled again after arriving at the well site; image 3 , because the derrick does not go down, the transportation height is too high, and the transportation height of different drilling rig types is at least greater than 40 meters; there is also a vehicle-mounted drilling rig, which is transported together with the derrick and the main module (including drawworks, diesel engine, gearbox and other equipment), such as Figure 4 , and the base must be disassembled into parts for transportation. In addition, since the vehicle-mounted drilling derricks all have guyline derricks, they cannot be used in desert environments; the transfer efficiency of these methods is too low

Embodiment 1

[0039] Such as Figure 5-14 , a new fast-moving drilling rig derrick 5 base 2 structure, which includes:

[0040] The base 2 is equipped with a detachable rear trailer 1 and a trailer frame 3 respectively at its rear end and front end;

[0041] Derrick 5, it is installed on the described base 2, and can keep vertical state or lay flat state on the described base 2, and vertical state is as Figure 5 , Figure 6 , in a flat state such as Figure 7 , 8 ,9;

[0042] A jacking device capable of vertically lifting the base 2 and the trailer frame 3 is installed on the base 2 and the trailer frame 3 .

[0043] In this embodiment, the structure of the base 2 further includes a derrick lifting cylinder 12, the derrick 5 is hinged to the base 2, and the two ends of the derrick lifting cylinder 12 are connected to the trailer frame 3 and the derrick 5 respectively. Hinged; the derrick 5 adopts a telescopic structure without a guy rope, which includes an upper section 20 of the der...

Abstract

The present invention relates to the field of petroleum drilling equipment, in particular to a new type of fast-moving drilling rig derrick base structure, which includes: on the base, and can maintain a vertical state or a flat state on the base; the base and the trailer frame are installed with a jacking device that can make the base and the trailer frame vertically lift; the purpose of the invention is to provide a disassembly Short time, low transport height, suitable for desert environment, and high transport efficiency of the new type of rapid transport drilling rig derrick base structure.

Description

technical field [0001] The invention relates to the field of oil drilling equipment, in particular to a novel fast-moving drilling rig derrick base structure. Background technique [0002] At present, most of the towed and transported oilfield derricks and bases are transported separately, such as figure 1 , 2 , due to the high center of gravity of the derrick, the reliability is poor when it is moved to the trailer device before moving, and the derrick and the base must be assembled again after arriving at the well site; image 3 , because the derrick does not go down, the transportation height is too high, and the transportation height of different drilling rig types is at least greater than 40 meters; there is also a vehicle-mounted drilling rig, which is transported together with the derrick and the main module (including drawworks, diesel engine, gearbox and other equipment), such as Figure 4 , and the base must be disassembled into parts for transportation. In addit...
