Development Of Intelligent Data Interface Of The Equipment In Drilling Well Site

At present, information sources in drilling sites are complex and various. The formats in different data systems are not standard and unified. This weakness makes the drilling information lack extensibility and opening capability, so the information can't be used in the other data systems. The data system in the drilling sites becomes"isolated island". In order to realize the drilling information sharing, especially for the needs of the digital construction of the oilfield, an intelligent data interface of the drilling sites is designed. Main works are as follows:According to the feature of the drilling data, the data formats of the different data sources in the drilling sites are analyzed. A method is determined to realize the intelligent data interface of the drilling well site. And the scheme to design the interface is proposed.In JAVA platform, the module design of the intelligent data interface is achieved by the XML middleware. The connection between JAVA program and the table of the well sites is completed using JDBC. The highly effective data inquiry is completed using index, with high efficiency of data transformation and data migration. More, the mapping between the database and the XML documents is established. At last, the interface realized data transformation and data migration between different data sources in well sites.Based on the intelligent data interface, a standard data fusion flat is designed and developed. The range of the interface is extended. The transparent access to the database is realized. The flat can meet the needs of the drilling well sites.The real time data treatment and conversion is achieved by the method of time transformation. To a certain extent, it meets the needs of the application in the drilling site. The results of the simulation shows that this intelligent data interface can realize the compatibility of the different data sources in the well sites. To some extent, the interface accomplishes resource sharing and comprehensive application of the drilling information.
