【摘要】 提出圈闭评价的技术路线 ,以二连盆地 8个圈闭的评价为应用实例 ,介绍圈闭评价系统 (TrapDEM2 .0 )的功能。TrapDEM2 .0由圈闭参数描述、圈闭评价和圈闭数据管理 3部分组成。圈闭参数描述部分包括 4个模块 (构造演化史恢复模块 ,盖层评价模块 ,断层侧向封堵模块 ,参数分布研究模块 ) ,在这些模块中采用了先进的平衡剖面技术、灰聚类评价技术、断层泥涂抹分析技术等。圈闭评价部分包括 5个模块 (地质评价 ,资料可信度评价 ,资源量或储量评价 ,经济评价 ,综合优选 ) ,在地质评价中采用了风险概率分析法、模糊数学法、加权平均法、专家系统法、人工神经网络法等技术方法 ;在资源量 (或储量 )评价中采用了蒙特卡罗法和数论法 ;在经济评价中采用了财务评价 (现金流 )和最小经济油田分析法 ;在综合优选中采用了双因素叠加分析法和多因素综合评判法。圈闭数据管理部分包括 3个模块(基础数据库管理 ,报表库管理 ,图形库管理 )。图 3表 3参 3更多还原

【Abstract】 The authors advance the technical route for the evaluation of traps and introduce the functions of the software of Trap Evaluation System (TrapDEM2.0), taking the evaluation of eight traps in Erlian basin as application examples.The software package of Trap Evaluation System (TrapDEM2.0) consists of three models: trap parameter description, trap evaluation and trap database management. The first model consists of four modules: restoration of structural evolution of trap, seal assessment, fault seal prediction, and parameter distribution, in which some of the advanced techniques such as balanced section, gray method and smear coefficient analysis of fault are used. The second model consists of five modules: geology evaluation, data reliability assessment, resource/reserve calculation, economical assessment, and comprehensive selection. The techniques such as risk analysis, fuzzy theory, weighted mean, expert system, artificial neural networks are utilized in its second module, Monte Carlo and number theory are used in the third module, financial evaluation (cash flow) and minimum economical oil field analysis are adopted in the fourth module and double factor superposition analysis in the last module. The third model is composed of three modules: basic data management, report management and graphic management.更多还原
