受井资料不足的制约，基于井资料的 HM 地区沉积微相分析精度不能满足该区隐蔽油藏精细勘探的要求；应用地震属性技术开展沉积微相分析则存在单属性解释精度低、多属性联合解释工作量大且难以统一的问题。为此，把地层切片技术、多属性融合技术及三相联合解释技术应用到 HM 地区沉积微相研究，建立了地震相平面解释配套技术方法。实际应用表明该方法充分利用了地震资料横向密集连续的特性，能够对地质体进行精细成像，对于以寻找单一砂体为目标的隐蔽油气藏勘探，尤其是在缺乏钻井的浅湖-半深湖地区，具有明显的优势。

Due to the lack of well data,the accuracy of sedimentary microfacies analysis based on well data could not meet the requirement of subtle reservoir exploration. In the analysis of sedimentary microfacies by using seismic attribute technique,there were also problems of low accuracy in single attribute interpretation and disunity in laborious multi attrib-utes interpretation. In order to solve these problems,the techniques of strata seismic slice extraction,seismic attributes fu-sion and three - phase interpretation were applied in HM area and the corresponding method of seismic plane sedimentary interpretation was established. The actual applications show that this method takes full advantage of high horizontal resolu-tion of seismic data,can carry out precise imaging of geological body,and has obvious advantages in the exploration of sub-tle reservoir for single sand - body,especially in the deep - water area with few wells.
