Abstract:

Petroleum Assessment System(PASYS) is a large-scale application software developed and used in the third oil and gas resource assessment of the PetroChina Company Limited.The PASYS provided the uniform critirion,methodology and assessment flow.Based on the management of database and graph database,this system focuses on petroleum resource assessment by integrating three sub-systems for basin evaluations,play(block) evaluations,economic evaluations with other modules.The integrative evaluation and modeling of basin,play or block can be made by this system.These sub-systems are relatively independent and can also be combined as an integrative system.The system was developed by using the OOB software language C++ Builder,Visual C++,and the database platforms of SQL Server and Microsoft Access were used in the system.This system is advanced in the assessment methods,convenient in operation,and successively run with Chinese interfaces and Client/Server mode.In the third petroleum resource assessment implemented by the PetroChina Company Limited,the scale-area database,parameter database,result database and graphic database for oil and gas resource assessment were established.The satisfactory results have been obtained in the third assessment,and the software and data can be applied to future daily and dynamic petroleum resource research.

Key words: oil and gas resource assessment, software, database, graphic database, applied effectiveness

摘要：

油气资源评价系统(PASYS)是在中国石油天然气股份有限公司第三次油气资源评价中统一开发和使用的大型应用软件系统,它为本次资源评价提供了统一的评价标准、方法体系和评价流程.整个系统以油气资源评价为中心,在功能强大的数据库和图形库平台基础上,将盆地评价、区带(区块)评价、经济评价3大应用子系统及若干辅助功能模块(如图形矢量化、图形编辑、地质符号编辑)有机地集成在统一的平台下,可以对盆地级、区带级、区块级等地质目标进行综合评价、模拟计算和资源评价.各应用子系统既保持相对的独立性,彼此间又具有有机的联系,形成了完整的资源评价体系.在计算机技术上,本系统采用最新的面向对象的C++Builder和Visual C++语言进行研制开发,数据总库采用SQL Server数据库平台,本地库采用Access平台.整个系统具有方法先进、功能实用、操作简便、交互性强、软件集成度高、全中文界面和支持客户/服务器工作模式等特点,在中国石油天然气股份有限公司的第三次资源评价中取得了令人满意的应用效果,同时首次建立了油气资源评价的刻度区库、基础库、成果库和图形库,为今后油气资源的日常、动态评价提供了软件和数据支持.
