Simulator function

The simulator provides training for different posts such as driller, driller assistant, drilling crew technician, drilling crew leader, drilling supervisor, etc. The simulation training can enable trainee to master the skills of soft/ hard shut-in, and conventional/unconventional well killing.

The simulator adopts mathematical models to simulate various working condition and parameters in petroleum engineering drilling operation, such as pressure, torque, ROP, flow rate, etc. and can reflect the relations between these parameters, which realizes the same effect as in real drilling operation.

The simulator enables user to set various drilling parameters, such as drilling string assembly, well structure, formation parameters, device parameters, etc. which makes the training more flexible and targeted. The software program adopts non-sequence structure, which can simulate various rig operation, and closer to reality. Virtual reality technology makes up a vivid perceptual environment, and 3D animation is synchronic with the real operation.

F&Q

  • What is a petroleum simulator?

A simulator is a device that simulates an environment for the purpose of training or research. A petroleum simulator is a set of devices that simulates the well site environment, the real operation devices, the operation method, parameter display way, etc. with which trainees can be access to a virtual well site environment, where they can get familiar with the relative devices, how to operate the devices, what phenomenon there will be if there is a problem, what’s happening underground, etc.

  • Why is your simulator better than other simulators I’ve used in the past?
