摘　　要：针对四川盆地须家河组的测试选层这一关键问题,总结了主要油气层段测试选层的测录井判识方法,即录井中具有"钻时加快、全烃上升、泥浆粘度上升、井温下降、密度下降、漏失泥浆"等裂缝型气藏录井特征;测井资料具有"声波时差升高、电阻降低、密度降低、井温降低、全波测井能量衰减、成像测井裂缝发育"等关键特征。通过在生产实践中推广运用,验证了该方法的可靠性,在裂缝型气藏勘探开发领域具有一定的推广意义。In allusion to the key problem of testing-selection zones in Xujiagou Formation,log identifying methods used for testing and selecting zones in major reservoirs including the main characteristics of drilling time acceleration,full hydrocarbon raising,mud viscosity increase,well temperature and density decrease,mud loss in voggy reservoir logging data were summed up,it had the characters of time difference of acoustic logging increase,resistivity and density decrease,well temperature reduction,energy of full waveform acoustic logging weakening,fracture growth in imaging logging.The method is introduced in production,it demonstrates that the method is reliable and validate,it is significance to be introduced in fractured and vuggy gas reservoir exploration and development.
