The Design And Implementation Of National Geological Drilling Information Collecting System

As a kind of important original geological data,drilling information has many features such as multi-sourced,heterogeneous,and numerous.This data often is stored in the form of charts and texts.However,due to its relatively different storage patterns,preservation conditions and management levels,a series of problems have been caused,including the inconsistency of collected input formats,large space consumption,and the difficulty of resource sharing.Furthermore,it also causes trouble and inconvenience to the people who are occupied in related design and decision-making.Therefore,it is particularly significant to establish a high-efficiency and accurate geological drilling information collecting system for taking recording projects,recording formats,and retrieving items as research objects with geological drilling dataBy designing a reasonable and efficient data table structure,this paper unifies and standardizes the input items and formats of geological drilling information.Besides,it also enacts an input standard which basically solves the problem of different data standards.And on the basis of a unified and standardized database,the paper introduces the design and implementation of eight function modules including data input,data query and statistics,data summarization,data import and export,data reporting,system maintenance,data report printing and system help.As for data entry and data import,the system will check the integrity of the input data using regular expression and offer detailed tips when there is wrong information.During data reporting and data summarization,the system will establish a strict data filter and data inspection mechanism to ensure the integrity of the data,so as to achieve data sharing and exchange.With the functions of report printing and data import and export,the system is able to manage bulk data,which provide efficient and convenient services for the input and management of massive drilling information.In addition,by using HTML and CSS technologies,this paper designs and develops a dynamic engine for managing drilling property.This engine can dynamically generate an information input interface based on the changes in the drilling property table,which not only saves development costs but also enables efficient input of complex and numerous drilling property information.The research and development of this system contribute to the optimization of management mode of geological drilling information in the Ministry of Land and Resources.Additionally,it improved the utilization efficiency of geological drilling information and the convenience of resource sharing at all levels of geological exploration units.Since the establishment of the project,the system has been extended to all levels of the country's geological prospecting units.According to statistics from relevant departments of the Ministry of Land and Resources,as of the end of 2017,more than 900,000 pieces of drilling data and nearly 100 million pieces of picture materials in the size of 100MB have been input.Such a large number of standardized drilling information has provided strong data support for China's"prospecting breakthrough strategy".
