圈闭预探勘探开发一体化评价方法与应用

The integrated model of assessing traps and its application in the stage of pre-exploration

目的为圈闭预探决策提供科学、直观、数字化结果,以降低油气勘探的风险。方法地质风险分析方法、经济评价方法。结果油气勘探开发是一动态的过程,以决策为目的的评价工作也应该是动态的,应从勘探开发一体化的角度来进行;以商业勘探行为决策为目的的评价应包括地质评价和经济评价两方面;根据圈闭预探阶段的特点建立了圈闭预探阶段的勘探—开发一体化评价模型,结合实例对评价流程做了详细的介绍。结论地质评价是整个油气勘探评价工作的基础,而经济评价得到的反映勘探目标价值或勘探项目未来收益能力的经济评价指标对勘探决策才真正具有指导意义。

Aim To provide reasonable, numerical outcomes to reduce the exploring risks. Methods Geological risk analysis and economic evaluation. Results Because the exploring and developing processes are dynamic, the assessment processes should use the integrated approach including geologic analysis and economic evaluation to assess traps. An integrated model of assessing traps in the stage of pre-exploration is founded and the steps and data needed in the assessment process is introduced. Conclusion The assessments in the stage of pre-exploring prospects should not only think much of geologic analysis, but also emphasis on economic evaluation. Although the geologic analysis is the basis of the assessments, the outcomes of the economic evaluation is the virtual benefits to the exploration decision.
