摘　　要：塔里木盆地塔中北坡目标井区志留系柯坪塔格组是典型的超深层致密砂岩薄储层,其埋深大、储层物性差.如何去识别这种超深埋致密砂岩储层"甜点"是本区储层预测的难点.针对这一难题,对该工区的测井曲线进行了分析,找出敏感曲线,并将波形指示反演这一高分辨率反演方法应用于该工区,详细开展了剖面和平面上致密砂岩"甜点"预测研究.结果表明,波形指示反演的砂体预测结果同时提高了纵向和横向分辨率,与已知钻井结果吻合较好,同时也符合工区的沉积规律,证明了波形指示反演应用于超深层致密砂岩薄互层储层预测的有效性.The target well area in northern slope of middle Tarim Basin is a typical tight thin super deep reservoir. The buried depth of the well area is very large,the physical characteristics of reservoir is poor. The difficulty in such reservoirs is identification of ＂Sweet Spot＂. According to this problem,we analyzed the logging curve and picked the sensitivity ones. Then seismic motion inversion is applied on this area. It turned out that seismic motion inversion can improve the vertical and lateral resolution. The results are coincides with the logging data,and it also consistent with the sedimentary regularity of this area,which proves the effectiveness of seismic motion inversion in identification of tight thin super deep reservoirs.
