摘　　要：塔河油田三叠系阿克库勒组四段河道砂体具有埋藏超深、砂体薄、河道窄的特点,在沉积微相研究指导下,形成了一套正演模拟技术定标志、地震多属性识别技术定边界、地层切片技术定期次和拟声波测井约束波阻抗反演技术定厚度的河道砂体识别描述技术。并在此基础上,针对河道砂体油藏分段成藏、隔夹层分布广泛等地质特征,形成了一套导眼评价与台阶状水平井开发相结合的高效井位部署技术,降低了各河道段油藏评价的风险,提高了河道砂体油藏的储量动用程度,在应用中取得了较好效果,对类似岩性油藏开发具有一定借鉴意义。The channel sand body in the 4th member of Triassic Akekule formation in Tahe oil field is characterized by ultra deep burial,thin sand body and narrow river channel.With the guidance of the study on sedimentary microfacies,a set of channel sand body identifica-tion and description technologies have been established,which uses forward modeling technology to determine marker,seismic multi-attri-bute identification technology to determine boundary,stratigraphic slicing technology to determine period and pseudo-sonic well-log-con-strained impedance inversion technology to determine thickness.Based on which,a set of efficient well placement technologies combining pilot evaluation and step-like horizontal well development has been formed regarding segment reservoir accumulation of channel sand body with wide distribution of interlayer and barrier,which can reduce the risk in reservoir evaluation and improve reserves producing degree of channel sand body reservoir.Good application effects have been gained and the technologies can be the references for similar lithological reservoir development.
