The invention relates to a combined type movable living module of a multifunctional self-elevating supporting platform for an ocean oil field, which is characterized in that longitudinal sliding beams of the platform are provided with a base; the base is provided with layered parallelly-arranged box bodies with same volume; one ends of each layer of box bodies positioned at two outer sides of the arranged box bodies are provided with escape windows and staircases communicated from top to bottom, and the other ends of the same are provided with washrooms and shower rooms; one ends of the bottommost layer of box bodies positioned at the two outer sides of the arranged box bodies are provided with doors for entering the box bodies; the middles of the box bodies arranged between the outer side box bodies are provided with passages communicated from left to right, and both ends of the box bodies arranged between the outer side box bodies are provided with living rooms with windows. The combined type movable living module is in a splicing structure of the layered parallelly-arranged box bodies with the same volume, thereby being convenient for the lifting operation of the movable living module, that is to say, uses can use a self crane of the platform to carry out lifting without using large-sized floating crane equipment, thereby saving the operation time and also reducing the operation cost of the platform; and besides, the invention also has comfort and safe accommodation and attractive appearance.
