Abstract：Several approximate elastic wave equations in which reflection and conversionare weaker than in accurate ones are first discussed in the paper. They include three elastic wave equations involving weak conversion and weak reflection, and one elastic wave equation having no conversion. Weak reflection and weak conversion make the elastic wave equations be applicable to the elastic-wave reverse time recursion image problem where interbed reverberation must be suppressed thoroughly. A trial example of elastic wave image proves this research result useful.
