摘要： 塔河油田近年在岩性油气藏勘探中取得了重大的突破,发现并落实了阿克亚苏2号上油组复合圈闭、塔河南中油组河道砂体岩性圈闭等,在其上部署的AT2、YT2等井都喜获工业油气流,展示了三叠系岩性油气藏领域的良好勘探前景。在层序地层学和沉积微相研究的基础上,采用层序地层学方法、岩性体的岩石物理特征与模型正演技术、地震属性提取与综合分析、波形分析技术、全三维可视化地震解释、基于模式的地震反演技术、砂岩厚度预测技术和油气检测技术对塔河油田三叠系岩性圈闭进行了识别和评价。

Abstract: The great breakthrough has been made in Tahe oilfield in recent years for Triassic lithologic reservoir exploration. The complex trap of upper oil measure in Akeyasu-2 well and the lithologic trap of channel sand body of middle oil measure in southern Tahe oilfield were found, on which Well AT2 and Well YT2, etc. were drilled and commercial oil-gas flows were gained, revealing a good prospect for Triassic lithologic reservoir exploration. This paper presents the identification and evaluation of the Triassic lithologic traps in Tahe oilfield based on the combination technologies such as sequence stratigraphy, sedimentary microfacies study, petrophysical properties, forward modeling, seismic attribute, waveform analysis, 3D visual seismic interpretation, seismic inversion, sand thickness prediction and oil-gas detection, etc.

Key words: Tahe oilfield, Triassic, lithologic trap, identification, evaluation
