【摘要】 为进一步了解松南梨树断陷火石岭组火山岩储层的地震响应特征,指导火山岩体的地震资料解译及成藏期次的识别,以实际地震资料为基础,结合钻井信息及地质认识,构建了火山岩地质模型,利用非平稳随机介质模拟技术对火山岩地震响应进行了正演模拟。通过正演模拟计算,得到并分析了由浅至深各反射层系及沉积相带的地震反射特征,从而为明确本地区火山岩响应规律,进一步检验地震地质解译模型建造的准确性,加深对本区火山岩成藏规律的认识提供依据。更多还原

【Abstract】 In order to understand the seismic response characteristics of Huoshiling Formation volcanic reservoir in Lishu fault,guide the interpretation of seismic data and identify the reservoir period,the authors build the volcanic model combing with the drilling information and geological recognition,and do forward modeling to volcanic seismic response using non - stationary random medium modeling.Through forward modeling calculation,the authors analyze the seismic response characteristics of each layers and sedimentary facies zone from shallow to deep, which provides the evidence for clearing the volcanic reponse regularity,testing the veracity of geological and seismic interpretation model and deeping the knowledge of reservoir-forming rule of volcanic rocks in studied area.更多还原
