摘要
与常规的剖面解释和传统的平面划相不同,平面岩相解释法是利用三维地震资料横向密集连续性好的特点,将地震属性信息与储层层序和地质过程相结合,运用地层切片技术、多属性融合成像技术、平面岩相自动追踪解释技术,结合地震资料、测井资料和钻井资料相,最终在平面上再现地下地层的岩相图像。在松辽盆地南部QD工区河流相储层研究中的应用结果表明,该方法具有解释精度高、速度快、微相解释和构造细节清楚等特点,在岩性油气藏勘探开发中具有广阔的应用前景。
Being different from the conventional section interpretation and the usual drawing facies,the plane lithofacies interpretation make the full use of the characters of 3D seismic data which are intensive and continuous in horizontal,combine the seismic attributes,information with the sequences of reservoir and geological process,and compared with the seismic data,the log and drilling data to image the subsurface formation rock facies by the stratal slicing,the plane facies automatic tracing interpretation,multi-attributes blending imaging technology.The result from QD area in the Songliao Basin shows that the method has a lot of good characteristics,such as high precision and fast speed, the micro-facies interpretation and structural details are clear.
