摘要
通过对研究区 FMI成像测井和 XMAC,DSI测井等资料的综合研究 ,并结合该区的油气地质、地球物理资料 ,对下奥陶统缝洞型碳酸盐岩古岩溶储层的剖面结构及展布特征进行了较为深入地分析结果表明 ,研究区古岩溶储层主要分布于下奥陶统顶部不整合面之下约 2 5 0 m的范围内 ,储层垂向发育具有明显分带性 ,岩溶剖面的纵向分带与该区多期次岩溶旋回作用密切相关。古岩溶储层的发育与分布受多种因素控制。
Based on FMI (Fullbore Formation Microimage),XMAC,DSI etc.data,combined with petroleum geology as well as geophysical data,the karst controlled reservoir of fissure cave type in the lower Ordovician strata of Tahe oil field was studied.Some characteristics of the paleokarst reservoir in profile were described in the paper.Paleokarst reservoir was well developed and distributed at 250 m below the unconformity in lower Ordovician,and characterized by vertical karst zonation,which was related to multiphase karst cycles.Controlling factors of Paleokarst reservoir development were discussed in the paper.
