川东北地区含硫气井钻井事故数据库系统

为了有效存储和合理利用川东北地区已钻井的事故数据，提高钻井事故数据管理的效率，设计开发了钻井事故数据库系统。以Microsoft Access为关系数据库管理工具，Visual Basic为用户访问端的开发工具，利用SQL实现数据统计分析功能。现场试验证明：利用该数据库系统可方便快捷地对钻井事故进行采集、存储、查询、统计与分析，为钻井事故原因分析、风险评估以及事故预防提供数据支持。以川东北地区钻井事故为对象开发的钻井事故数据库系统，加快了钻井事故科学化、数字化管理的进程，是钻井信息化的重要补充。

The database system for drilling accidents of high sour gas wells in northeast Sichuan basin

In order to keep and make good use of the data of drilling accidents occurred in northeast Sichuan basin and improve the efficiency of management on the drilling accidents data, a database system for drilling accidents was designed and developed.  The Microsoft Access was used as the relevant database management tool, the software was developed by Visual Basic programming language, using SQL to achieve the function of statistical analysis for the accidents data. The field tests show that the parameters featuring drilling accidents can be readily collected, stored, accessed and analyzed by using the Database System of Drilling Accidents (DSDA). The DSDA can be used for cause identification and failure analysis, risk assessment and accident prevention. The database system for drilling accidents in the northeastern Sichuan basin incidents has sped up the scientific and digital management of drilling accidents. It is an important supplement for drilling informatization.
