The development of computer and network techniques afford the technical foundation of construction design and the management information of construction procedure for geological drilling. On the basis of analyzing the information flow and information system requirements in geological drilling, this paper proposed the general frame and technical plans of construction management information system of geological drilling mainly by the information interactive platform of drilling techniques, design system of drilling construction and the management information system of drilling construction procedure, including 8 function modules of contract management, design management, borehole management, apparatus management, materials management, statistical statement, leader's attention and record management. By the implementation of this system, the technical level of geological drilling design, construction and management can be significantly improved with good application prospect.
