Abstract

The invention provides a self-lifting type drilling platform. The self-lifting type drilling platform comprises a main ship body, and a cantilever beam which is arranged on the main ship body, whereinan eccentric type derrick is fixedly connected on the cantilever beam; a drilling tool is arranged in the vertical direction in the eccentric type derrick, and is used for downwards extending into aseabed to perform drilling operation; the eccentric type derrick comprises an un-eccentric type base frame and an eccentric type eccentric frame, wherein the gravity center of the eccentric frame deviates from the geometric center of the base frame in a direction away from the main ship body; and the drilling tool deviates from the position of the geometric center of the base frame in the direction away from the main ship body, so that a drilling operation range is increased, and therefore, the drilling operation process is simplified, drilling time history and an operation period are shortened, and comprehensive operation cost is reduced.

Description

technical field [0001] The invention relates to the field of marine engineering construction, in particular to a jack-up drilling platform suitable for oil and gas exploitation operations in shallow sea areas. Background technique [0002] With the continuous development of the world's economy and technology, the actual demand of human society for land and ocean energy is still growing. Usually, mobile platforms of various structures and uses are the main equipment for exploration, development and utilization of these offshore oil and gas resources. [0003] There are various structural types of mobile platforms, and jack-up drilling platforms, jack-up oil production platforms, jack-up workover platforms and jack-up living platforms are often used in offshore waters. The drilling device of the jack-up drilling platform is set on the main hull through the cantilever beam, and the cantilever beam is extended or retracted relative to the main hull to realize the change of the d...
