摘要
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 。
On the basis of summing up the geological and production data obtained before, response rules of resistivity log, acoustic log, natural gamma ray log, spontaneous potential log and caliper log in fractured reservoirs of metamorphic rock and the rules of logging response changing with depth increase in tight section are studied.A new method is proposed for identifying fractured zones by using multi-logging plot combination of removing the logging response increasing with depth and regular changing of background value in the tight section . Examples show that good result is obtained for identifying fractured reservoirs in the metamorphic rock with the new method.
