摘　　要：为助力古龙页岩油地质研究,加深对油井压裂改造参数及不同层段返排情况的认识,依据勘探数据,选用生产测井组合仪和超声波多普勒三相流测井仪,对一口油井在其压裂返排后期开展了三相流组合测井。获得了不同油嘴尺寸生产条件下分层产出数据,包括产出流体性质和层段油气水产量贡献率,明确了各层段产水、产油贡献率与压裂改造参数、采排制度的相关性。To help the research in Gulong shale oil geology and get better understanding of oil well fracturing parameters and flowback conditions of different intervals,the PLT and the ultrasonic Doppler three-phase flow logging tool were selected based on the exploration data,and three-phase flow combination logging was carried out in an oil well in the late stage of fracturing flowback.Layered production data,including the property of produced fluid and contribution rates of oil,gas and water production of each interval,were obtained under different oil well production conditions controlled by nozzle sizes.The correlation between water and oil production,contribution rates of each interval,the fracturing parameters and the flowback and production programme is clarified.
