Design And Implementation Of Drilling Well History Data Management System

With the rapid development of oilfield digitization,the oilfield industry has a higher pursuit of data quality.In order to adapt to the rapid development of the oilfield industry,the oilfield system also needs to be continuously updated.Due to the insufficient ability and level of the staff,in addition,there are many problems such as diverse historical data,inconsistent version numbers,and differences in databases of different versions.This leads to data loss and omissions during the update process of the oilfield system,which reduces the standardization of data and is not conducive to data management.This thesis is based on the business needs of an oilfield company,committed to the research on the well history data governance system of the oil field,discuss the implementation method of data governance in the oil field,and designed and implemented a drilling well history data management system,which will improve the data of the oilfield company.The quality of management has certain guiding significance.The main content of the thesis research is:(1)This thesis mainly explains and summarizes theoretical knowledge including DAMA data management knowledge system,DGI data governance framework and IBM data governance maturity model.Then it analyzes the current status of oilfield data and the existing problems.(2)From the perspective of data governance,this thesis analyzes the needs of the oilfield system from six aspects: data sources,well history data,governance rules,data governance,role permissions and business logic.On the basis of demand analysis,the overall design of the system is carried out,design of modules including data governance,rule making and database.(3)This thesis uses C# programming language,.NET framework and Web front-end technology to implement a drilling well history data management system.And through the coordinated operation between the various modules,the data management needs of the entire system are met,and the purpose of drilling well history data management is realized.In short,data governance has become the key to data applications in current oilfield companies.The rule-making module in the system of this thesis can quickly process the data accordingly.The data governance module can perform standard governance on data according to the rules formulated,thereby greatly improving the standardization and quality of data.This research has certain reference value in oilfield data governance.
