Title: Optimization and countermeasures for PetroChina exploration and development informationization systems——Dagang oilfield as example
Abstract: The management system of dada of exploration and production technology(A1system for short)and management system of production data of oil-gas-water wells(or simplyA2for short)are the service system of exploration and development and dada management.In accordance with comprehensive planning of information technology,PetroChina built this to cover the oilfield regularly,uniformly,safely and efficiently.Since this system is in line with the generally international standard of integrated data model,we can use it to realize the integration of exploration and development,form regular working process gradually and improve the scientific nature of the business planning and decisionmaking.Since the application systems,introduced and developed these years,are based on the longitudinal development professionally and are dependent on each other,we can not operate them on the systems of A1and A2directly so that the application efficiency of system is affected.Therefore,based on the system architecture of information structure of exploration and development at present,this article knows that the main restricting factors are the insufficient coverage of EPDM data model,the low degree and poor pertinence of comprehensive applicative layer and the huge work during data transmission and synchronization.So,taking the geophysical entity for example,it uses the technology of heterogeneous database integration and accomplish the construction of logic center master database layer after the model expansion of center master database.Then,key technology and blockdiagram of applicative system integration and interface development are done after the analysis of that basis.As shown in practice,new deployment scheme can meet the increasing scientific research and production requirements,enrich the application components of service bus further and improve the overall scientific research level and production efficiency of Dagang oilfield.
