井震多因素综合确定的解释方法与应用效果
The interpretation method and application effect determined by multiple seismic and logging factors
【摘要】 鄂尔多斯盆地因巨厚的黄土覆盖造成地震资料信噪比低,解释难度大。文章以该盆地盐定地区延长组中下部为例,利用钻井岩-电分析结果,对地震资料进行精细确定、解释及质量控制,提高了层序地层划分图、沉积相图、砂岩厚度图和构造图等的质量,这项成果在盐定地区勘探中取得了良好的效果。
【Abstract】 The interpretation is difficult because of the low signal-to-noise caused by the thick loess deposited in Ordos Basin.The authors choose the mid-lower part of Yanchang Formation in Yanding area to demarcate and interpret seismic data accurately and control its quality with using lithology interpretation and electrical analysis of drilling.This process improves the quality and precision of the sequence stratigraphic division map,sedimentary facies map,sandstone thickness map,structural map and so on.The good results have been achieved in the risk exploration in Yanding area.
