陕北延长组天然裂缝特征的综合辨识

Intrinsic Fracture Identification of Yanchang Formation in Northern Shaanxi

通过野外露头观察、储层岩芯的室内观测、油井压裂数据和生产动态数据的分析以及测井曲线的解释等四种方法对陕北地区延长组低渗透砂岩油藏储层中的天然裂缝发育特征进行了综合辨识,使用这四种方法对该区域裂缝进行全面识别更加简易可行。

Through four methods, observation of the field exposure, indoor survey of reservoir core, analysis of oil well fracturing data and production dynamic data and interpretation of well log, synthetically identified natural frac- ture of low permeability sandstone reservoir of Yanchang formation in Northern Shaanxi. The four methods to com- prehensive recognize fracture is more simple and feasible in this area.
