摘要
油气预测技术是地震资料处理和解释领域的热点之一。本文通过对共反射点叠加法和线性褶积模型的原理和存在问题的分析指出，基于水平叠加（偏移）资料的现行各种油气预测技术只对地表和地下情况简单的地区的油气预测有参考价值，而对地表和地下情况复杂的地区的油气预测还难以胜任。要想提高油气预测技术的可靠性，扩大其应用范围，必须提高叠前各处理环节的精度、采用餐前信息进行反演、研究新的地震记录理论模型和进一步了解油气藏的地震波反射机制。
Hydrocarbon prediction technique is one of people's interests in seismic dataprocessing and interpretation. Having analysed the principles and problems of CDPstacking and linear convolution model,I deem that existing hydrocarbon predictiontechniques based on horizontal stacked (migrated) data are only applicable to hydrocarbon prediction in the area where surface and subsurface conditions are simple,butfails to achieve hydrocarbon prediction in complicated area. In order to improve the reliability and applicability of hydrocarbon prediction techniques,people must do accurate data processings before stacking,make inversion by using prestacked informations,research into new theoretical model of seismic records,and thoroughly ascertain the reflection mechanism of seismic waves from hydrocarbon reservoir.
