摘要
通过对裂缝的识别和裂缝参数的定量计算,建立起应用成像测井资料进行储层评价的成像测井模式并对地应力进行了分析。研究区最大水平地应力方向为北西-南东向,与张开的走向一致。后期水平应力对高角度裂缝有改造作用。当高角度缝的走向与最大水平主应力的方向一致时,后期水平应力对裂缝有保持作用;反之,具有破坏和闭合作用。
The interpretation mode is established and ground stress is analysed through identification of the fractures and quantitative calculation of the fracture parameters.The biggest horizontal ground stress is northwest-southeast direction,which corresponds with the ringent trend.The anaphase horizontal stress has reconstruction effect on the high angle fractures.When the trend of high angle fractures has the same direction with the biggest horizontal principal stress, the anaphase horizontal stress will preserve the primary fracture. Otherwise, fractures will be destroyed and closed.
