非零偏VSP技术在油田复杂断块开发中的应用

Application of non zero offset VSP technology to oilfields with complex faults exploitation

非零VSP是一种地面激发,井中接收的地震观测技术.其信号能量强,频带宽,波场信息丰富.能够获得"三高"的地震反射信息.针对复杂断块油田开发后期的精细描述,非零VSP是一项有效的开发地震技术手段.多年来,在三维地震资料品质较差情况下,VSP是对三维地震信息的一种补充,解决了辽河油田复杂断块开发中存在的小断层、薄砂体认识不清的许多地质问题.为油田复杂断块开发提供了一种有效的技术手段.

None zero offset VSP is a seismic observation technology, which excites on the ground and receives in the well. It has strong energy signal , wide band, and rich wave field information. It can get ＂three high＂ seismic reflection information. For fine description of the complex fault oilfield in late exploitation, non zero offset VSP is an efficient seismic technology means. For years, under poorer 3D seismic data quality, VSP is a supplement to the 3D seismic information. It solves many geophysical problems in distinguishing small faults and thin sand bodies in Liaohe oilfield. It provides an effective technological means for exploiting oilfield with complex fault.
