远探测声波技术在碳酸盐岩储层改造中的应用

The Application of Remote Detection Acoustic Wave Technique to Carbonate Reservoir Reconstruction

准确的储层综合评价是储层改造的前提,常规测井可以准确描述井筒储层的发育情况,而远探测声波测井技术可以探测井旁约30m以内的储层发育情况,二者结合,可使储层描述更为精细。介绍了远探测声波测井技术在碳酸盐岩储层综合评价和储层改造设计中的应用。借助远探测声波测井技术提供的井旁储层发育层段可以更准确地确定射孔和改造层段,结合井旁储层发育的规模可以优化设计改造液用量。改造后的酸压测试解释得到的井旁储集体发育特征与远探测声波测井技术解释结论相吻合,二者资料相互印证,证实了远探测声波测井技术资料的可靠性及其在优化储层改造设计的成功应用。

Accurate reservoir evaluation is the premise of reservoir reconstruction.The conventional logging can describe accurately the developmental condition of wellbore reservoir,but the logging technique of the remote detection acoustic wave is capable to detect the developmental condition of reservoir nearly 30 meters beside a wellbore and combination of two could more accurately describe the reservoir.This paper introduces the application of remote detection acoustic wave logging technique to reservoir reconstruction in carbonate formation.The reservoir development section of the well provided by the remote detection acoustic wave logging technique can determine accurately the perforation and transformationlayer and it can design optimally the consumption of reforming liquid.The post-performance of acid pressure test indicates that the reservoir developmental characters nearby well is the same as the interpretation results of remote detection acoustic wave logging technique.The result shows that this technique is reliable and has an effective application in optimal reservoir reconstruction.
