塔中顺南地区奥陶系缝洞型储层地震响应特征正演模拟分析
|
摘要
针对塔中顺南地区奥陶系碳酸盐岩储层埋藏深度大、发育规模小、非均质性强、反射类型多样和储层地震响应特征不清等问题,在精细分析三维地震资料的基础上,结合该区钻井、测井及地质综合解释等资料,建立了不同类型缝洞储层的地震地质模型,通过改变储层结构形态、发育规模及缝洞发育位置等因素来模拟分析目标储层的地震响应特征变化,在此基础上总结并建立了研究区域缝洞型储层的地震识别模式,为顺南地区奥陶系缝洞型储层的有效预测提供了参考依据。
The carbonate reservoir of the Ordovician in Shunnan area of central Tarim Basin,usually has a larger burying depth,small scale,high heterogeneity and multiple types of reflection,of which the seismic response characteristics are unclear.On the base of fine analysis of 3Dseismic data,combined with the actual drilling,logging and geological data,the geological models for different types of fracture-cavity reservoir are established.By changing the reservoir's morphology,development scale,spatial development location and other factors,the change of seismic responses characteristics of target reservoir are simulated and studied.And based on that,seismic recognition pattern of fracture-cavity reservoir in this area is concluded and built,which provides a reference for the prediction of fracture-cavity Ordovician reservoir in Shunnan area.
