Analysis and Application of New Acid Fracturing Technology for Carbonate Reservoir in Offshore Deep Well with High TemperatureBy Hongzhi Xu, Yubing Wang, Zhiwei Hao, Yousheng Song, Junyu Deng, Wenna Zhao
Abstract: Acid fracturing is the key production and stimulation technology for the oil-gas reservoirs. This paper developed Loss Control Acid and Divert Acid System used in the Bohai Bay Nan-pu oilfield Ordovician carbonate reservoir, which has the problems of deep reservoir burial depth, high temperature, well developed fracture and cavern and high anisotropy. This formation used to be acid fractured with gelled acid and it responded poorly. It also has a …
