摘　　要：塔里木盆地某重点地区奥陶系碳酸盐岩发育断控储集体,明确储层反射特征及储集体结构是开展储集体识别及评价的基础。针对该区断控缝洞型油气藏的地质特点和面临的勘探难点,通过正演模拟根据钻测录等资料建立合理的地质模型,并赋予相应的物理参数来认识储集体地震响应特征是一种较为有效的方法。本次研究根据该区断控储集体实际地质特征,设计合理的断控储集体模型开展地震正演模拟,系统分析不同模型与地震响应特征、储层非均质性与地震响应特征之间的关系,为进一步厘清高产井地震特征及识别模式奠定基础。fault-controlled reservoirs are developed in Ordovician carbonate rocks in a key area of Tarim Basin basin.Reservoir identification and evaluation are based on reservoir reflection characteristics and reservoir structure.According to the geological characteristics and exploration difficulties of fracture-vuggy reservoir in this area,a reasonable geological model is established by forward modeling based on drilling and logging data,it is an effective method to assign the corresponding physical parameters to recognize the seismic response characteristics of reservoir.Based on the actual geological characteristics of the fault controlled reservoir in the area,this study designed a reasonable fault-controlled reservoir model to carry out seismic forward modeling,the relationships between different models and seismic response characteristics,reservoir heterogeneity and seismic response characteristics are systematically analyzed,which lays a foundation for further clarifying seismic characteristics and identifying patterns of high-yield wells.
