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.
