摘要(Abstract)：

随着地震勘探工作的逐步深入 ,资料解释过程中常规合成地震记录与实际地震剖面难以匹配的问题更加突出。针对这一问题研制出的变频法合成地震记录 ,提高了两者的匹配程度 ,可以更加精细地区分地震反射层位 ,更好地分析岩性变化对地震数据的影响 ,明确地震反射波形变化的地质含义 ,以达到储层预测的最佳效果。该方法实用性强、算法合理、方便快捷 ,可以根据需要随时更改模型 ,为解释人员进行地震资料的地层解释提供了一个环境良好的实用工具 ,有助于研究岩性圈闭油气藏
With the further development of seismic exploration the problem that the conventional composite seismic record is difficult to match with the actual seismic profile during seismic data interpretation becomes more serious. In order to resolve this problem frequency converting method is studied to composite seismic record and it improves the matching ability. This method more accurately distinguishes the seismic reflection horizon, analyzes the effect of lithologic change on the seismic data and clearly defines the geologic significance of seismic inflection wave shape change to get the best results of reservoir prediction. This method is convenient and quick to use. The model can be changed constantly according to your need. It is a good tool for interpretation workers to carry out stratigraphic interpretation of the seismic data. It is useful to research lithologic trap hydrocarbon reservoir.
