Problems solved by technology

[0002] At present, most of the dragging and transportation of oil field derricks and bases are carried 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; there is also a complete tow rig , such as Figure 3, because the derrick is not lowered, the transportation height Too high, the transportation he...

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 , Image 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 derr...

Abstract

The invention relates to the field of petroleum drilling equipment and in particular relates to a novel rapid moving drilling rig derrick base structure. The novel rapid moving drilling rig derrick base structure comprises a base and a derrick, wherein a rear trailer and a trailer frame which can be detached are arranged at the rear end and front end of the base, respectively; the derrick is arranged on the base and can be kept at a vertical state or a horizontal state on the base; a jacking device through which the base and the trailer frame can lift in the vertical direction is arranged on the base and the trailer frame. The invention aims to provide a novel rapid moving drilling rig derrick base structure which is short in detachment time, large in transport height, suitable for a desert environment and high in moving efficiency.

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 addi...
