The invention discloses a derrick lifting holding pole for an oil well and a lifting method. The derrick lifting holding pole comprises a main holding pole body, small holding pole bodies and lifting systems. The main holding pole body is divided into three sections including an upper section body, a middle section body and a lower section body. The lower ends of the small holding pole bodies are hinged to a rotary disk, and the rotary disk is installed on the upper section body. A top rotating base is installed above the rotary disk and at the top end of the upper section body. Each lifting system comprises a driving device and a lifting steel wire rope, wherein according to the driving device, the lifting steel wire rope is wound around a lifting ground pulley, a pulley on the middle section body, a pulley on the lower section body, a pulley on the top rotating base and pulleys on the small holding pole bodies in sequence and then is fixedly connected to a holding pole pulley frame at the top ends of the small holding pole bodies. The holding pole is an inner suspension holding pole, heavy things are lifted through a built derrick in derrick construction, and efficiency is high. All the pulleys are arranged on the pole bodies, and therefore the pulleys are lifted while the holding pole is lifted. The derrick lifting holding pole is suitable for construction of various derricks, and materials and the design cost can be saved.
