【摘要】 对反射地震偏移成像问题进行了分析、对比与探讨 ,并对各种偏移方法如叠后时间偏移、叠后深度偏移、叠前时间偏移、叠前深度偏移和它们之间在地质效果上的异同进行了讨论。认为 ,在当前的地面观测记录的质量条件下 ,叠后时间偏移和叠后深度偏移 ,叠前时间偏移和叠前深度偏移 ,都有各自的优势和不足。因此 ,它们都有应用价值 ,不是互相排斥 ,而是互相补充。今后的方向是发展和完善高分辨率和高保真度的偏移成像方法。在这方面还有许多问题要解决。更多还原

【Abstract】 This paper discusses issues concerning reflection seismic migration imaging A comparison on geological effects between different migration methods such as post stack time migration,post stack depth migration,pre stack time migration,and pre stack depth migration is given The author believes that given the current surface recording conditions,post stack time migration and post stack depth migration,or pre stack time migration and pre stack depth migration all have advantages and disadvantages Therefore they are complementary,not exclusive,having their own application values The trend is to develop and perfect high resolution and high fidelity migration imaging methods In this respect there are a lot of problems to be solved更多还原
