The invention relates to a lifting type supporting platform for an offshore oilfield. The platform comprises three pile legs, wherein a fixed living building and a helicopter deck are mounted at the front end of the platform; two cranes are mounted at the left and right ends of the platform; two parallel longitudinal sliding beams as well as bases and driving devices thereof are mounted at the rear end of the platform; two parallel crossbeams capable of moving along the longitudinal sliding beams are mounted on the longitudinal sliding beams; a drilling machine workbench which moves along the crossbeams is mounted on the two crossbeams; a detachable rectangular base and a living module are mounted on the longitudinal sliding beams; the living module comprises multiple layers of box bodies which are in the same size and are provided with doors and windows, so that a space over the sliding beams can be fully utilized, and the living supporting function is added; a quickly-lapped hydraulically-telescopic walking trestle with a rotary base and a hydraulic multifunctional conveying trestle are mounted at the right side end of the platform; in-place anchor machines are mounted at four corners of the platform. Thus, the functions of conveying water, electric power, telecommunication signals, fuel, steam, drilling fluid, completion fluid, cement and the like from one platform to another platform are added; moreover, the platform is in place conveniently, quickly and accurately, the using functions are expanded, the working efficiency is improved, and the oil exploitation cost is reduced.
