地震反射法的目的就是要把地下数百米到数千米深处的地层的形态(产状)和性质(岩性)通过地震资料反映出来。要想把地层的产状、岩性和含油气性搞清楚,就必须把反射波的振幅信息、相位信息和速度信息全面地提取出来并分别和综合编制出各种地震地质图象。这些图象的正确性取决于上述地震信息提取的精度。但是由于实际介质的复杂性,全面地、正确地提取上述各种信息是很困难的。不过在一定的近拟程度上从地震资料中提取的各种信息还是有价值的,而且随着理论与实践的进展,这种近拟程度也
The purpose of the seismic reflection method is to reflect the formation (appearance) and the nature (lithology) of the formation hundreds of meters to thousands of meters below the earth by seismic data. In order to understand the formation, lithology and oil-gas formation of the strata, it is necessary to fully extract the amplitude, phase and velocity information of the reflected waves and to separately and comprehensively prepare various seismic geological images. The correctness of these images depends on the accuracy of the above seismic information extraction. However, due to the complexity of the actual media, it is very difficult to comprehensively and correctly extract the above various information. However, at a certain degree of near-degree from the seismic data extracted a variety of information is still valuable, but with the progress of theory and practice, this degree of near-zero
