【摘要】 由于塔河油田灰岩裂缝性储层非均质性强、横向连通性差,需要对其进行有效的酸化压裂改造以获得具有经济价值的油气产能.近几年来,多极子阵列声波测井仪(主要DSI和XMAC)已投入塔河油田测井现场服务,这些新的声波测井资料经合适的软件处理后可获的极为丰富的地层信息.本文讨论了我们编制的多极子阵列声波测井资料处理软件及其在塔河油田酸压设计施工中的应用.通过多极子阵列声波测井资料处理得到的岩石力学特性分析,确定了地层应力的大小和方向,计算出酸化压裂所需的压力以及压裂后压裂缝的高度.计算结果在实际施工中得到了很好验证.更多还原

【Abstract】 Multipole array sonic logging tools have widely been employed in Chinese oilfields in recent years.We developed a software package for rock mechanical analysis with multipole array sonic logs.This advanced data processing method and software have been applied to Tahe oilfield in Northern West China to provide guidance to acid hydraulic fracturing design and evaluation.In this paper,we present the field examples of such data processing and applications to demonstrate the validity and advantages of our method and software package.更多还原
