摘要

地震勘探技术应用可以分为以二维地震研究构造为主的地震勘探初级阶段、以地震地层学为主的地震勘探中级阶段、以三维地震油藏静态描述为主的地震勘探高级阶段、以地震储层研究为主的开发地震初级阶段和以四维地震进行油藏监测为主的开发地震高级阶段。针对 5个不同阶段的地质条件和地质任务 ,选择使用合理的地震勘探技术是有效提高勘探开发效益的重要途径。焉耆盆地的勘探开发体现了以地震勘探为主的思路 ,在勘探开发过程中重视了针对不同勘探开发阶段和不同的地质目标选择合理的地震技术 ,因此 ,在早期勘探开发中取得了很好的经济效益。
Application of seismic exploration technique can be divided into primary exploration phase mainly being study of structure by 2-D seismic prospecting,middle exploration phase mainly being seismic stratigraphy,high exploration phase mainly being static description of reservoir by 3-D seismic exploration,primary development seismic phase mainly being seismic reservoir study and high development seismic phase mainly being reservoir monitoring by 4-D seismic exploration.Aimed at the five different phases,selective use of reasonable seismic exploration technique is important way to effectively improve exploration and development benefit.The exploration and development in Yanqi basin reflect the train of thought mainly by using seismic exploration technique and pays attention to select reasonable seismic technology at differentexploration and development phase and aimed at different geologic targets in their exploration and development process, which gained good economic benefits in their early exploration and development.
