摘要
本文利用地层倾角测井裂缝识别DCA资料,采用多井统计方法,解释了两种不同岩性(安山岩和碳酸盐岩)裂缝性储层的裂缝分布规律。本文提供的实例表明应用地层倾角测井DCA资料可解释清楚油气藏中裂缝在纵、横向上的分布规律,能可靠地反映地层裂缝分布方位,找出高产区域。
This paper presents a study of fracture distribution with DCA curves on fracture identification logs recorded by dipmeter tools, by using multiple-well statistical method. The fracture distribution is analyzed in the formations of two kinds of lithologies (andesite and carbonatite). Practical example shows that the vertical and horizontal distribution of fractures can be studied from DCA curves in gasoil bearing reservoirs. So fracture distribution orientation will be revealed and high productivity area can be determined.
