Abstract:In the construction of some information system for oil&gas exploration and production, it's likely to result in irregularity of reported data types, disunity of data accuracy, inconsistency of data statistics and dissatisfaction of interrelated data items to business rules. This is mainly due to the coverage of exploration, development and engineering business, the large quantity of reported data items and data, as well as the variety of reported ways. In order to solve these problems, we summarize six verification methods including data item, column, row, cross multi-table, historical data, Singular Value, and also their combined verification methods. We also design some verification policy on cross-business and cross-time comparison and Singular value analysis, which is in accord with petroleum exploration and production industry. On this basis, we further develop encapsulated technology of configuration and maintenance. It promotes the implementation efficiency of verification method.
