摘　　要：为了构建物探效果后评价体系、优化油气勘探开发决策、优选地震物探投资项目、促进技术发展、拓展应用效益,以塔里木盆地ST探区物探项目效果为研究对象,分析了14个项目全生命周期包含的技术效果、应用效果、经济效果3类主要评价指标,指出了纵向5级的评价指标体系设计路线和计算方法。研究结果表明:①SN41N等3个项目效果优、为Ⅰ类,AD等9个项目效果中、为Ⅱ类,仅2个项目效果差、为Ⅲ类;②经复验,评价结果符合研究区实际。结论认为:①研究区需要持续提升地震资料采集和处理的技术水平,深化油气成藏地质条件研究,提升钻井储层保护技术,加快物探成果的应用;②该方法可以找出物探项目之间的共性、差异及原因,可以为技术发展提供支撑,有助于提高物探项目的管理效率和勘探效益;③该方法体现了物探项目的全过程产出效果及物探贡献价值,具有可量化、实用性强等特点,具有一定的科学性、合理性和可操作性。Taken fourteen geophysical prospecting projects in ST block as examples,three appraisal indexes including technical,application and economic effect were discussed for these projects during their full lifecycle in an effort to create the post evaluation system of prospecting effect,optimize exploration and development strategies,select the project access to investment,increase technical process and expand application profits.In addition,both route plan and computing work-flow were proposed for the appraisal index system with five levels in the transverse direction.Results show that(i)among these fourteen projects,three ones like SN41N are regarded as the type I project due to excellent effect,nine ones such as AD with moderate effect as the type II,and the rest two projects with poor effect as the type III;and(ii)the re-inspection also demonstrates the appraisal results in line with practice in the study area.In conclusion,it is essential to continuously upgrade technological level in acquisition and interpretation of seismic data,to deepen the research on geological condi-tions to form reservoirs,to improve reservoir-protection skills,and to speed up the popularization of prospecting achieve-ments.Figuring out the similarity and difference and their origin,our methodology may support technical advancement and is conducive to enhancing both management efficiency and exploration benefits for the projects.With quantifiable and at-tainable natures and strong practicality,the scientific and rational methodology gives expression to output efficiency and contributory value in projects'total process.
