Methods And Technologies Research On Data Governance Of Data Application In Oil And Gas Field Exploration And Exploration

Oil and gas field completed internet and IOT by two decades of oil and gas data construction,which provides the assurance for data digitalization and sharing,especially the finding of data center through entering all of paper documents,reports and images which were accumulated a decade or even a hundred years into oil and gas companies.But,there are data island and fragmentization due to diversified construction which consist of different issues,different suppliers,different technologies and methods,this is a long process in oil and gas company on data construction.Data governance is proposed these years as an engineering for solving the data island,which asked the engineers to use DT mindset for rebuilding the data which produced from IT way of thinking and to activate the data in for visiting more faster.For the practical data governance,oil and gas fields must be carried out the engineering of data governance by one retouch alteration for the existing data problems.Data governance is the research object in thesis which makes investigation about principle thinking,concept,connotation and denotation,as well as various of ideas.Both theory methods and key technologies were focused in oil and gas field data governance,good results were achieved with applying all of the disquisitive methods and technologies.The main contents in thesis as follows:1)The concept of data governance,the achievements of previous studies,philosophies and methods was described,the basic architecture was built for data governance in oil and gas field,the basic model was given,the methods were highlighted the whole research.2)Three key technologies of data driven were referred on the theory of data governance,which composed of work-flow modeling technology,data scrubbing and correlation search technology,it provide the theory and technical supporting for data governance software program by investigation and study of these technologies.3)One set of data governance tools was designed out in this thesis,which applied the visualization flow programming technology,the specialists assembled the relative nodes for compiling the work flow of data governance and application without programming which running in the local machine as well as accessing to cloud for automatic running,the latter one executes an order by touching.4)The common application contexts which composed of semi-structured historical data accessed,self-help data analysis and data applied were selected by applying the proposed theory,modeling and method in oil and gas data governance,which is proved the feasibility of data governance methods and high efficiency of software,this provides reference for similar data management work in the future.Three highlights are obtained in this thesis as below:1)The data governance model is proposed for exploration,development,production in oil and gas field.From pose and philosophy to basic approach,the basic system is constructed,the data governance model is given,and the basic road-map is sketched.2)One set of system software which used for data governance was designed with features of zero program,processize,node operation,scenario,visualization.Based on the research of data governance key technologies for oil and gas fields,the software system conduct the data,make the business process and complete the data acquisition,organization,integration,extraction,as well as formal expression by nodes combination according to the context demands.This software comply the principle of zero code,the user only arrange and combine various function nodes without complex program,the integration and application for large number of data from more resources in the difference structures can be carried out.3)The new model of oilfield data governance is explored.The research of software in thesis was applied data governance in oil and gas field,such as data compilation and storage in Changqing Oilfield Company,data governance in CNPC Greatwall Drilling Company and specific data governance engineering in Daqing Oilfield Company,all of these practicals produced the new model.In brief,data governance is a critical puzzle on data application and big data technology in oil and gas companies who asked the data to play the major rule and drive the value,so the implement of the overall and exhaustive data governance engineering is required.
