摘要 

四川盆地西北部雷口坡组勘探潜力大,随着勘探的深入,多口钻井在雷口坡组雷三3亚段油气显示活跃,测井解释储层较为发育,含气性好。针对雷口坡组含气有利区分布不清的问题,首先结合川西北地区地震地质情况和钻测井资料,通过经验模态分解技术高分辨率处理,在保持低频信号的同时抬升高频能量,有效拓宽了地震数据的频宽,为双相介质油气检测技术提供了资料基础。基于单井目的层位置处的频谱分析与标定,发现目的层含气时频谱表现为低频能量相对增强,高频能量相对减弱的特征,优选敏感频率范围,利用基于双相介质理论的油气检测技术对研究区开展储层含气性检测,油气检测结果与实钻井和地质规律匹配较好,证实了该技术在研究区应用的可靠性,为川西北部雷口坡组扩大勘探领域提供了指导方向。

Abstract

The Leikoupo Formation in northwest Sichuan Basin has great potential in exploration,quite a few wells demonstrate active oil and gas showings during drilling,and good gas-bearing property and reservoir development are interpreted from well logging.Aiming at tackling the unclear distribution of favorable gas-bearing zones of Leikoupo Formation and based on the combination of seismic geological conditions and well logging data,the authors conducted Empirical Mode Decomposition processing to compensate high-frequency energy while preserving the low-frequency energy,which laid the data basis for subsequent bi-media hydrocarbon detection technique.Then amplitude spectrums at different well locations were compared and analyzed,the low-frequency energy enhancement and high-frequency energy attenuation were found where reservoir contained gas.With the optimized frequency range,hydrocarbon detection based on two-phase media theory was implemented on the seismic data of the study area.The results of hydrocarbon detection are well consistent with the data from drilling wells and the geological law,which confirms the validity of proposed techniques and provides the directions for expanding oil and gas exploration range and area of Leikoupo Formation in northwest Sichuan Basin.
