Oil-Field Drilling Virtual Simulation System
油田钻井虚拟仿真系统

Based on computer simulation technology,parametric oil-field drilling virtual simulation system is created.The motion of virtual equipments is controlled by parameters to simulate the drilling processes realistically.The development framework of virtual simulation system based on numerical simulation technology and visual simulation technology is proposed.The mathematical models of hoisting system and rotating system are analyzed and formed to control the motion of virtual equipments.Furthermore,real-time deformable simulation of a rope passing through several pulleys is achieved.Finally,to realize the interaction of the system,initializing of the system parameters,displaying and controlling of the drilling process parameters in real-time are achieved.
