Problems solved by technology

[0003] At present, existing jack-up drilling platforms can be divided into notch-type platforms and cantilever-type platforms. The notch-type platform has a notch at the stern of the main hull, and the drill floor and derrick are located above the notch. The drill pipe goes down through the notch to reach the bottom of the sea for operation. This type of platform has a large comprehensive drilling load, but the number of piles inserted per drilling is small and the efficiency is low.

Abstract

The invention provides a notch cantilever self-elevating drilling platform, which includes a main hull, a cantilever beam, a drilling mechanism and a sliding mechanism. The end of the stern of the main hull is notched. The cantilever beam is supported on the main hull and covers the notch, and can move between the initial position and the beyond position along the longitudinal direction of the main hull. In the initial position, the cantilever beam is located on the main hull as a whole, and drilling can be carried out inside the hull For operation, when in the over position, the cantilever beam at least partially exceeds the main hull, protrudes from the stern of the main hull, and can carry out drilling operations outside the hull. The drilling mechanism is arranged on the cantilever beam. The sliding mechanism includes a driving part, a first connecting part and a second connecting part. The first connecting part is arranged on the main hull, and the second connecting part is arranged on the cantilever beam. The first connecting part is engaged with the second connecting part, and the motor can drive the second connecting part. The first connecting part moves, thereby driving the second connecting part and the cantilever beam to move together.

Description

technical field [0001] The invention relates to a drilling platform, in particular to a slotted self-elevating drilling platform with a cantilever beam. Background technique [0002] Jack-up drilling platform is a kind of mobile offshore drilling equipment, which generally has no self-propelled capability. It has the advantages of strong positioning ability, good mobility, and flexible operation. It is widely used in the field of offshore oil and gas exploration and development. [0003] At present, existing jack-up drilling platforms can be divided into notch-type platforms and cantilever-type platforms. The notch-type platform has a notch at the stern of the main hull, and the drill floor and derrick are located above the notch. The drill pipe goes down through the notch to reach the bottom of the sea for operation. This kind of platform has a large comprehensive load for drilling, but the number of piles inserted each time is small and the efficiency is low. The cantilev...
