塔河油田三叠系阿四段河道砂岩岩性圈闭是2010年塔河油田增储上产的重要目标,前期三叠系主要以寻找构造型圈闭为主要目的,随着勘探开发的深入及构造圈闭的日益匮乏,寻找岩性圈闭及油气藏迫在眉睫。针对油气显示良好的阿四段储层,综合运用全三维地震解释、属性综合分析、频谱分析、波阻抗反演技术等多种地震解释技术,对阿四段河道砂体进行识别与描述,指导了开发井位的部署与实施,为塔河油田的增储上产作出了积极贡献;同时,为寻找岩性圈闭积累了宝贵经验。

The lithologic traps of T2a4 are important for production in the Tahe Oil Field.During theearly stage,structural traps were focused on in the Triassic formation.As explorations expanded,It haSbecome more and more difficult to find structural traps.So,it is necessary to look for lithologic trapsand reservoirs.Technological methods such as 3D seismic interpretation,comprehensive analysis ofproperties,spectrum analysis and impedance inversion have been used in the T2a4 reservoirs.The than-nel sandbody of TZa has been distinguished and described,which may guide the deployment and imple-mentation of development wells.The studies contribute to the production increasing in the Tahe OilField and provide valuable experience for litholo}ic traps searching.
