基于GIS的勘探钻孔信息管理自动化研究

Automatic Management of Geological Information from Exploration Drilling Based on GIS

勘探钻孔中各岩层的岩性和物性等地质信息的自动化管理与勘探钻孔柱状图的自动成图一直是勘探部门期待解决的课题.作者根据石油勘探生产和科研要求建立了勘探钻孔地质信息数据库,并基于GIS思想提出了一种自动分段绘制勘探钻孔柱状图的算法,解决了勘探钻孔平面分布的二维空间信息和属性信息的双向查询以及钻孔中各岩层的三维空间信息和属性信息的双向查询,为勘探钻孔信息管理的自动化提供了一种新的思路和方法.

The main problem which expect to solve for exploration department is to manage automatically geological information from exploration drill hole and draw automatically drill columns. The author sets up drill geological information database according to oil-gas exploration and scientific research request, describes the structure and function of drill database in detail. In the meantime, the paper provides a kind of algorithm which draws automatically exploration drill columns based on GIS, and resolves the problem of bidirectional query of drill hole or terrane between spatial information and feature information. The research of project also is a kind of new idea and method in managing automatization of the exploration drill information.
