基于伪阻抗体波形聚类的贝壳灰岩储层预测方法
Coquina reservoir prediction method of seismic pseudo-impedance waveform clustering
摘要
Abstract
Carbonate reservoir plays an important role in the global oil and gas distribution,and its reserves account for a-bout 50% of total oil and gas reserves.Coquina is a kind of important carbonate reservoir,which is characterized by strong het-erogeneity,and the difference of conventional rock physical characteristics between coquina and surrounding rock is not obvi-ous.Therefore,it is difficult to predict its favorable reservoir distribution.On the basis of analyzing the characteristics of rock physics and seismic facies of coquina reservoir,this paper makes clear the difference between the coquina and its surrounding rocks.Then,seismic pseudo-impedance is calculated by predictive deconvolution to characterize the inner seismic refection, which is used to predict coquina distribution by waveform clustering method.Finally,the prediction result is discussed by the sedimentary microfacies and ancient geographical analysis.Meanwhile,the prediction is consistent with the drilling result dem-onstrating the method is reliable and effective.关键词
