The invention discloses a self-installation oil production platform. The oil production platform is a self-elevating-type platform and a crude oil tank is arranged in a platform body. A pipeline trestle is arranged on the stern portion of a main deck, a flare boom and a flare liquid separation tank are arranged on a starboard on the stern portion of the main deck, the bow portion of the main deck is provided with an emergency generator room, an emergency distribution room, a machine repair room, a hydraulic station, nitrogen generating equipment and a tool room, oil gas processing equipment and an oil conveying arm are arranged on the stern portion of a second-layer deck and the midship portion of the second-layer deck is provided with a hot oil boiler room, a transformer room, an oil production distribution room, a main distribution room, a main generator room and a natural gas generator room. The characteristics that an offshore drilling platform is movable and pile legs are in place are used in the self-installation oil production platform, the self-installation oil production platform integrates the functions of a fixed platform and the FPSO function, has the functions such as oil gas processing, crude oil storage and exportation, sewage treatment and life support, can be used repeatedly, greatly reduces the investment cost of oilfield development, and provides a technical support for marginal field development.
