摘要

为了准确确定地层超覆线、明确砂体地震相特征及识别描述薄储层,提出了利用地震正演模拟技术,以测井、地震、地质统计为基础,建立正演模型,分析了用地层夹角定量外推法准确确定地层超覆线、建立多模型确定砂体地震相特征及对波形进行分类确定薄储层展布特征的实际结果,认为应用该方法可解决油藏勘探的难题,降低勘探风险,取得良好的勘探效果。
In order to ascertain stratigraphic overlap line,define seismic facies features of sandbody and describe thin reservoir,the forward model is built up by using seismic forward modeling based on log,seismic and geological statistics was presented,the results of the stratigraphic overlap line actually ascertained by stratigraphic dip quantitative extrapolated method,seismic facies features of sandbody defined by multi-model and spread distribution features of the thin reservoir by waveshape classification was analyzed,it is thought that the method can be used to solve the problems in reservoir exploration,reduce the exploration risk and get a good result.
