摘　　要：缝洞发育程度是古潜山储层油气产量高低关键因素之一。现有的古潜山储层裂缝的随钻快速识别技术存在一定的局限性。笔者通过古潜山裂缝段发育的录井资料特点,通过利用综合分析现场钻遇潜山裂缝气测曲线形态、工程参数衍生参数功比值,并结合烃相态新录井技术中是否钻遇潜山裂缝HSG吸收率谱图变化特征,建立了基于录井资料在随钻过程中古潜山裂缝快速识别标准,该方法在西江凹陷的随钻解释工作中得到应用,且钻后电成像测井作业中验证了方法的准确性,取得了良好的效果,为勘探作业提质增效提供技术支撑,具有一定的推广应用价值。The development degree of fractures and caverns is one of the key factors for oil and gas production in buried hill reservoirs.The existing rapid identification technology of fractures while drilling in the buried hill reservoir has certain limitations.Based on the characteristics of logging data of fracture section development in buried hill,by comprehensively analyzing the shape of gas measurement curve and parameter work ratio derived from engineering parameters of in-situ drilling into buried hill fractures,and combined with the change characteristics of HSG absorption spectrum of whether drilling into buried hill fractures in the new hydrocarbon phase logging technology,the author established a rapid identification standard for middle buried hill fractures during drilling based on logging data.The method has been applied in the interpretation while drilling in Xijiang Sag and the accuracy of the method has been verified in the post-drilling electrical imaging logging operations,and good results have been obtained.It provides technical support for improving the quality and efficiency of exploration operations,and has certain popularization and application value.
