在总结以前地质及开采资料的基础上 ,研究了变质岩裂缝性储层中电阻率测井、声波测井、自然伽马测井、自然电位测井、井径等的响应规律和在致密层段测井响应随深度增加的变化规律 ,提出了采用消除致密层的测井响应随深度增加而有规律变化的背景值的多条测井曲线组合划分裂缝带的新方法。实例表明 ,应用这种新方法划分变质岩裂缝性储层效果好
Based on the previous geological and mining data, the response laws of resistivity logging, sonic logging, gamma ray logging, natural potential well logging, well diameter and so on in fractured reservoirs of metamorphic rocks are studied. A new method to divide the fracture zone by combining multiple well logs with varying depth of well log responses with increasing depth is proposed. The example shows that the application of this new method is effective in dividing the fractured reservoirs of metamorphic rocks
