Description

Virtual reality's well drilling well site simulation system

Technical Field

The invention belongs to the technical field of petroleum drilling simulation system design, and particularly relates to a drilling well site simulation system with virtual reality.

Background

With the rapid development of today's digitizing and informatization systems in the industry, more and more enterprises map actual industrial processes onto informatization systems. In the petroleum drilling industry, simulation systems are increasingly chosen by businesses due to their realistic pictures, lower cost, high safety and flexible operability. The simulation system firstly needs 3D modeling software to model objects, and in addition, most importantly, a game engine is used for constructing scenes, driving and rendering, and finally, the simulation effect is presented by combining a control system of a program script.

The game engines which are widely used at present are mainly Unity3D and Unreal Engine, the Unreal Engine is better than Unity3D in picture effect, but the use method is more complicated, the configuration requirement of a computer is far higher than Unity3D, a certain fee is paid for enterprises to want to use more functions, the Unity3D is highly expandable, a small and medium-sized enterprise and independent game developers favor a low-level configuration and an unusual picture, and the Unity platform provides a complete set of complete software solution which can be used for creating, operating and rendering any real-time interactive 2D and 3D content, and the support platform comprises a mobile phone, a tablet computer, a PC, a game host, augmented reality and virtual reality equipment.

The existing drilling simulation system has the disadvantages that the drilling equipment is of an old type, and a new version of drilling machine which is rapidly developed does not accord with the specification, and the model and the scene need to be updated; the change of the data in the information system cannot be well reflected in the model scene, the mapping between the data and the model cannot be clearly reflected, and the data is not fed back on the simulation picture in time; generally, the existing simulation system does not consider the simulation of accidents, and when an operator performs simulation operation, the correctness of an operation flow cannot be represented through the accidents, the operator is only prompted to encounter the accidents through data, and the flow in teaching or demonstration aspects is deficient; poor picture feel, various images in the real world are not simulated in the existing system, so that the picture reality is reduced, and the substitution feel of an operator is reduced; the system only simulates various operations and responds to data changes, and the system does not provide timely prompts for operators, and does not timely communicate the prompt to the operators when encountering problems, so that teaching and demonstration are not facilitated.
