摘要: 通过对已钻井的储层特征分析,以及前人对串珠状异常反射岩溶缝洞型储层的成功经验以及岩溶缝洞型储层模型正演的结果为指导,应用均方根振幅体时间切片、振幅变化率和地震时间偏移剖面三结合的方法,在研究区中发现了一批岩溶缝洞型储层。通过构造图、古地貌等方法对串珠做了初步的划分评价。

Abstract: Based on analysis of reservoir characteristics of drilled well and successful experience of stu-dying string beads anomaly reflection on karst-fracture-cavity type reservoirs in Tahe oilfield,passelkaYSt-fracture-cavity type reservoirs had been discovered in the study area.The discovery was resul-ted from the forward modeling of karst-fracture-cavity type reservoirs,combining time slice of rootmean square amplitude,change rate of amplitude and seismic time migration section.The string beadsanomaly reflection was also classified and appraised by depicting the present structure and paleogeomor-phic characteristics and so on.
