摘要： 位于酒西盆地西部的青西油田由若干个深层裂缝性油气藏组成,裂缝是油气的主要储集空间,又是油气的主要渗流通道,主力油层段位于裂缝发育段内,油田内裂缝发育区为高产井区。目前已运用多种方法研究裂缝,诸如全直径岩心X-CT扫描、核磁共振分析、成像测井裂缝解释识别、三维地震相干数据体处理以及地震属性提取分析等手段,从裂缝静态特征描述、井筒周围裂缝评价、裂缝分布预测等方面研究裂缝,并确定裂缝发育层段及裂缝发育区分布。

Abstract: Qingxi oilfield, located in western Jiuxi basin of Gansu province, is composed of a number of deep fractured hydrocarbon reservoirs. Fractures are not only the primary petroleum-storage spaces,but also major percolation flow channel in this area. The major oil zone is situated in well-developed fractural zones which are generally high production areas in the oilfield. About these fractures,lots of techniques have been applied currently to study such as full diameter core's X-CT scanning,NMR analysis,fractural interpretation/identification by image log,3D seismic phase-interference data processing and seismic attribute extraction analysis,etc. These techniques can be used to study fractures by fractural static characterization fractural evaluation around wellbore and fractural distribution prediction, and to determine fracture developed zones and their distributions.

Key words: Jiuxi basin, Qingxi oilfield, reservoir, fracture, image log, fractural zone
