摘要
中国石油勘探开发应用系统是基于各专业纵向发展、相互独立开发的,在统一、规范的勘探开发信息化系统上难以直接运行,系统应用效率低.基于勘探开发信息化系统架构中存在EPDM数据模型覆盖面不够、综合应用层共享程度低、针对性差、数据传输与同步工作量大等问题,分析系统架构制约因素,提出优化方案和关键技术:利用异构数据库集成技术,以中心主数据库模型扩展为基础,搭建逻辑中心主数据库层,分析并制定应用系统集成及接口开发技术和框图.大港油田现场应用表明:系统架构优化方案丰富了服务总线的应用组件,能够满足油田科研信息化生产需求.
The management system of dada of exploration and production technology("A1"system for short)and management system of production data of oil-gas-water wells(or simply"A2"for 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.
