摘　　要：王集油田西区储层薄，分布不稳定，确定该区储层展布是实现勘探突破的关键因素之一．根据该区地质特点及资料，在岩电关系分析的基础上，通过波阻抗反演确定了该区核三段Ⅳ～Ⅶ油组砂体分布；采用地震波频率吸收处理技术，提高了纵向分辨率，确定了单砂层的展布规律．储层预测结果应用于该区滚动勘探取得了良好效果，新增150×10^4t石油控制储量．The western area of Wangji Oilfield is characterized by thin reservoirs,and the distribution of the reservoirs is instable.It is a key to the successful exploration of the area to determine the distribution of the reservoirs.Based on the analyses of the geologic feature and seismic data and litho-electric correlation,the sand-body distribution of H_3 Ⅳ～Ⅶ oil series in this area is predicted by wave impedance inversion.The vertical resolution of the prediction result is greatly improved by means of seismic wave absorption technique,and therefore the distribution of single thin layers is determined.The reservoir prediction result is applied to the rolling prospecting of this area,which makes petroleum probable reserves increase by about 1.5 million tons.
