Abstract

This invention provides a drilling management system based on a digital well site, comprising a connected dynamic simulation unit and a well control management unit. The dynamic simulation unit includes a collision avoidance analysis module, a drill string strength verification module, a well pressure loss module, a cementing parameter calculation module, and a wellbore simulation module. The collision avoidance analysis module calculates the inter-well distance and collision avoidance coefficient in real time. The drill string strength verification module confirms the axial load and tensile strength of the drill string at different well depths. The well pressure loss module acquires displacement, density, predicted well depth, and drill string data to confirm drilling hydraulic pressure loss. The cementing parameter calculation module calculates the overall elongation of the casing before cementing, as well as the elongation and displacement of the drill string assembly. The wellbore simulation module confirms the real-time displacement and position of the drill string in the wellbore, and calculates ECD, friction, and jamming prevention parameters in real time. The well control management unit includes a stationing module, a well control module, and a tripping / running analysis and evaluation module. This invention improves the work efficiency of drilling personnel.
