摘要
与常规地震方法相比,井间地震提高了地震资料的垂直与水平分辨率。根据井间地震的特点总结了井间地震资料解释的方法特点,介绍了井间地震资料解释在油气田勘探开发中的应用和发展。实际资料解释表明,利用井间地震资料发现了常规地震所不能发现和确定的小构造,精确描述了常规地震无法分辨的储层及其横向变化特点,并且描述了单砂体的空间分布。结果表明,井间地震资料实现了对地层、构造及储层等地质目标的精细描述。
Compared to conventional seismic,crosswell seismic is of higher vertical and horizontal resolutions.This paper summa- rized different crosswell seismic data interpretation techniques, and introduced briefly the applications and evolution of cross- well seismic in oil exploration & development.Practice showed that crosswell seismic data can outline minor structures that conventional seismic cannot reveal,can be used to determine reservoirs and their distributions that conventional seismic can- not distinguished,and to describe the spatial distribution of single sand bodies.We can achieve fine descriptions of geologic objects such as formations,structures,and reservoirs with cr- osswell seismic data.
