摘要
确定潜山地层应力方向是潜山储层评价的一个重要方面,地应力方向的准确分析能更好的判断裂缝的有效性,有助于揭示油气分布规律,预测油气富集区。本文介绍了利用测井的声、电成像、交叉偶极子等方法,可以方便准确地确定区块地层应力方向,利用成像资料确定的裂缝展布特征与区域地应力的关系,判断裂缝的有效性及压裂效果。
Determining the direction of formation stress is important to evaluation of reservoirs in Qianshang. Accurate analysis of the stress direction can help to judge fracture validity,to reveal hydrocarbon distribution law and to predict hydrocarbon enriching section .The paper introduces a method to determine the direction of formation stress accurately with acoustic, electrical imaging logging and crossed dipoles logging data. The relationship between fracture distribution characteristics and regional stress can be used to judge fracture validity and fracturing effect.
