中文摘要：

针对地质导向钻井过程的特殊性与复杂性，提出基于计算机支持的协同工作理论与虚拟现实技术相结合，构建一个支持多用户协同决策的虚拟可视化环境，该环境可将不同地点的钻井技术人员、专家通过网络组织在一起进行协同工作，从而使钻井工程作业达到高效、优质、安全、低成本的目标。详细描述了共享虚拟环境的体系结构及主要技术实现。

英文摘要：

Aiming at the particularity and complexity during geo-steering drilling processes, a multi-user cooperative work virtual environment constructed by the theory of CSCW and the technology of virtual reality is put forward. It can organize cooperative work in the network from drilling technicians and experts in different places, so that making the drilling tasks to reach the goal of high efficiency, good quality, safety and low costs. The system architecture and the realization of multi-user shared environments oriented geo-steering drilling are in detail described in this paper.
