摘　　要：塔河油田三叠系阿四段河道砂体具有埋藏深(>4 000m)、砂岩厚度薄(<10m)、横向变化快、地震识别难度大的特点。在小层对比的基础上,在沉积微相的约束下,综合应用多属性优选、时间切片、分频混色、三维可视化等技术描述砂体展布特征,形成了一套针对塔河油田三叠系阿四段超深层、薄砂层、窄河道砂体的"四定"储层识别与描述技术组合。Channel sand body for 4th member of Triassic Akekule Formation in Tahe Oilfield is character- ized by deep burial （〉 4 000 m）, thin sandstone （〈10 m）, and quick lateral changes, which make it diffi- cult to identify the characteristics of the seismic. Based on a small layer of contrast, under the constraints of sedimentary microfacies, this study integrated multi-attribute preferred application, time slicing, fre- quency mixing, 3D visualization techniques to describe sand body distribution characteristics, and has es- tablished a set of reservoir identification and description technology for super-deep, thin sand, narrow channel sand bodies for 4th member of Triassic Akekule Formation in Tahe Oilfield.
