Research of Visualization Intelligent Decision Support System for Drilling Risk Control

There were many lacks in traditional risk control systems,for example,the systems were mostly based on static information from ground,thereby difficult to accurately distinguish the actual situation "down hole" in real time,they could only solve a sole factor risk control problem,and moreover,their information was not intuitively revealed and could not be shared. So this paper proposes a Visualization Intelligent Decision Support System for Drilling Risk Control. A risk visualization analysis GIS system and intelligent decision-making models of risk control are built by use of WebGIS,case-based reasoning and network communication techniques. And an information-sharing and visualization decision-making support platform is provided for multi-domain experts and technicians in different locations to make cooperative decisions. The platform, which makes full use of all types of information as well as a variety of existing risk control methods,techniques,cases,multi-domain experts' experience and knowledge,can intuitively reveal the well location and distribution regularity of various types of potential risk in exploration area. In addition,it can achieve decision-making control of all risks in drilling engineering. This can improve risk decision-making and control in terms of science, accuracy and real-time. Details are provided about the architecture'design and key techniques of the system in this paper, including the building of intelligent decision-making models, asynchronous communication between the client and server,visualization of risk analysis, speedy loading and display of the map, and so forth.
