The rapid development of social economy in our country, the industry in innovation and development of the growing demand for oil, promote people to constantly increase the intensity of oilfield development, and oilfield development time prolonged, and the application of water injection production in the process of development, cause of formation pore pressure is more and more complex, as the new adjustment well drilling work more difficult. Therefore, the research on dynamic prediction methods of reservoir pore pressure in development Wells is intensified, which can predict reservoir pore pressure in development Wells in a short time, and the pore pressure can be predicted more accurately through the comparative analysis of predicted and measured pressure, providing strong support and guarantee for the design and construction of drilling engineering.
