Purpose: Drilling process is a complex process, the factors that affect the rate of drilling are complex. In order to optimize drilling parameters and real-time control, a dynamic model of drilling speed was proposed. Methods: The factors influencing the rate of penetration were analyzed, and the rate of penetration was established by systematic identification. Results: The drilling rate model of Chaheji area in Huabei Oilfield was established by this method, and satisfactory results were obtained. Conclusion: The dynamic drilling speed model can describe the drilling process more accurately and scientifically, and has broad application prospect in drilling parameter optimization and closed-loop control of drilling process.
