摘要：

塔河油田位于塔里木盆地北部沙雅隆起阿克库勒凸起,它的主体是奥陶系碳酸盐岩大型不整合-岩溶缝洞圈闭油藏,其上叠加成带分布的石炭系、三叠系低幅度背斜圈闭、岩性圈闭及复合型圈闭,由断裂、不整合连通形成次生油藏,纵向上具有"复式"成藏组合特征。塔河油田处于古克拉通盆地斜坡部位,在巨大生烃坳陷的边缘,丰富的油源是形成大油田的物质基础;长期发育的大型鼻状凸起控制油气运移、聚集与成藏,多期不整合是油气侧向运移的有效通道;断裂、裂缝及岩溶作用,形成了孔、洞、缝网络状储集体;良好的储盖组合是大油田形成的重要条件;长期生烃、多期次构造运动、多期次油气充注造就了现今复杂的油气聚集景观。

Abstract:

The Tahe oilfiled is located at the Arkekula salient of the Shaya uplift in the northern Tarim Basin.Its main body is the large scale unconformity-fractured-vuggy reservoir in the Ordovician carbonate.It is superposed by the Carboniferous and Triassic low amplitude anticlinal,lithologic and composite traps,which form secondary reservoirs through connection by faults and unconformities,and show vertically the characteristics of composite play.The Tahe oilfield occurs at the slope of paleo-craton basin and on the edge of large hydrocarbon kitchen. The rich resource rock is the material bases for the formation of large oilfield;the large nose shaped salient with long-term development controls hydrocarbon migration and accumulation;the multi-stage unconformities are effective pathways for lateral hydrocarbon migration;the faulting,fracturing and karstification form the network reservoir consisting of pore,fracture,rug;the favorable reservoir-seal assemblages are important conditions for forming large oilfield.The present complicated hydrocarbon accumulations are caused by long term hydrocarbon generation,multi-stage tectonic movements and multi-phase hydrocarbon charging.

Key words: hydrocarbon accumulation condition, enrichment rule, carbonate rock, Tahe oilfield
