地质导向钻井技术能够根据钻井、随钻测井等各项参数，实时判断是否钻遇油层以及油层位置，能够主动调整钻头前进方向，被认为是21世纪最有发展前景的钻井新技术。文中提出了地质导向钻井系统中地面决策系统的总体构思及主要功能，并利用 Visual C++ 6.0加以实现，该决策系统实现了实时钻井数据的管理与应用，主要功能包括查询统计、报表生成、实时曲线图、井眼轨迹等，良好的交互性为现场勘探人员进行决策提供了较好的技术支持，可进一步推广应用。

Geosteering while drilling technology could be used for real-time judgement of whether drilling reservoir or not and judgement of its position, for active regulation of drilling orientation, in accordance with drilling parameter, logging while drilling（LWD） parameter, and other parameters. It has been generally acknowledged as a new drilling technology with the most promising future in 21st Century. In this paper, the general idea and major functions of the ground decision-making system of the geosteering while drilling system are put forward, and Visual C++ 6.0 could be used to fulfill the management and application of real-time drilling data. The ground decision-making system could be used to make inquiry, record data, draw real-time curve, and generate hole trajectory. It provides favorable technological support for explorers on the site to make decisions for its good interactivity, and it could be popularized and applied further.
