潜山油藏一般具有地质结构复杂多变、储集层横向非均质性严重等特点，在计算地质储量时很难求准、求精储集层厚度。作者针对埕北古100潜山古生代地层垂向保留少、横向变化大、井间又难于对比的情况，通过综合分析建立地质模型，制作高精度的合成地震记录，准确标定潜山储集层，利用地震资料横向密集和连续的优势，应用测井约束波阻抗反演技术，比较好地求取了储量计算范围内的潜山储集层厚度，为储量计算打下了基础。

A buried hill oil reservoir is usually characterized by the complex geological structure and strong horizontal heterogeneity of a reservoir. Thus, it is difficult to obtain the accurate thickness of a reservoir. Palaeozoic formations barely exist in CBG100 buried hill and have great changes horizontally and are difficult to compare that of between the cross-boreholes. Based on the established geological model, this paper precisely calibrates the reservoir of the buried hill by making accurate synthetic seismogram. Because the seismic data are close and continuous horizontally, the accurate reservoir thickness of the buried hill is obtained by using the logging-restricted wave impedance inversion method. It offers reliable parameters for the reserve estimate.
