摘要
在简要介绍钻孔资料数据库设计、数据库结构、管理模式及入库工作流程的基础上，详细阐述了钻孔资料的综合管理和数据的分析应用，主要包括钻孔数据的统计分析、信息查询和信息提取技术方法等，基于该方法开展了岩石-地球化学分类统计、目标层砂体厚度、砂体埋深、泥岩厚度和砂地比等统计计算工作，利用统计计算得到的结果可编制层间氧化带前锋线及砂体的空间展布等图件。
On the basis of brief introduction to the design, structure, management model and the process of data verification and correction of drill hole data＇s database, synthetic management and analytic application, which mainly include such methods as statistical analysis, information inquirement and information extraction of drill hole data and so on, have been elaborated in detail. Using these methods, the authors have carried out classification statistics of petro-geochemistry, thickness of target layers＇ sand bodies, burial depth of sand bodies, thickness of mudstones and the ratio of sand bodies＇ thickness to target layers＇ thickness and so on. With the calculated results, the authors have edited the maps showing the spatial distribution of the interlayer oxidation front line and those of sand bodies.
