摘　　要：地震作为含油气盆地油气勘探的主要手段,在油气勘探中发挥了极其重要的作用。根据地震投资、工作量与地震勘探成果的大小、可靠程度和经济价值之间的关系,建立了地震预探效益评价指标体系。应用该指标体系可直接对具体油气区的地震预探效益进行相对评价。在此基础上,依据概率理论和盈亏平衡原理,建立了地震预探效益评价指标定量化方法和评级标准。并以新疆油田2001年—2010年三维地震预探为例进行了具体应用。结果表明该指标体系设计合理,定量方法与油田生产经营结合紧密,具有较强的实用性和客观性。Seismic exploration plays a very important role in oil and gas field exploration. Based on the relationship among seismic investment,work load and seismic exploration achievements,and reliability and economic value,an index system for seismic pre- prospect benefit evaluation is established for the first time.Relative evaluation for a specific petroliferous region can be performed with the index system. Then a quantified method and rating standard of the index system are established based on the probability and break even theories and has been applied in 3D seismic pre- prospect in Xinjiang oilfield. The result shows that the index system is reasonable and the quantified method is objective and applicable.
