VSP技术与常规地震观测方法相比,可减少噪声影响,提高纵向分辨率等诸多优势.通过VSP成像,结合地面三雏地震资料和岩性资料,进行精细地震属性分析,准确标定目的层,确定岩层之间的接触关系,建立准确的地质模型,进而对地层的非均质性进行研究.该文以松辽盆地南部南山湾地区为例,利用VSP资料,重新标定葡萄花油层的薄砂体,精细解释油层底界,在多种地震属性分析的基础上进行储层预测,绘制出沉积相图,对该区提出了有利勘探目标.

Compared with general seismic techniques,VSP can remove noise effect more effectively and improve vertical resolution.Combining 3D seismic profile and core,the key layers are calibrated,their relations can be made definitely,and fine seismic attributes analyses is processed.A more accurate geological model is set up and the reservoir heterogeneous can be made clearly by using VSP image.Taking Nanshanwan area for example,the thin sand of Putaohua oil layer can be recalibrated using VSP time-depth table,and its bottom can be interpreted accurately.The reservoir is predicted by several attributes analyses,and sedimentary facial map is established to put forward favorable exploration targets.
