中文摘要：

地层厚度作为重要的地质参数,是正确解释地下地层及构造特征的基础.目前常用的地层厚度计算方法,存在受地层倾角的约束,误差大,操作难度大等问题.依据地层校正原理,提出了一种操作简便、可靠性强的井震结合地层真厚度计算方法.该方法可以直接利用钻井资料或者地震资料计算地层真厚度,也可将两种资料获得的地层真厚度结合,获得地层厚度数据准确,且横向变化趋势清晰的地层真厚度图.经过南堡凹陷奥陶系地层的实际应用表明,该方法具有重要的实际应用价值.

英文摘要：

Formation thickness is an important parameter, It is the basic work for explaining buried formation and construction correctly. The calculating methods in common use are constrained by the dig of formation and hard to calculate, and the deviation is obvious for un-horizontal formation. By analyzing the current calculation method for formation thickness, this paper put forward an easy operation method for true formation thickness calculating based on well logging-seismic combination. The map of formation true thickness that obtained with this method not only has accurate thickness value, but also has clear lateral trend. After practical application of the Ordovician in the Nanpu Sag show that the method has important practical value.
