文摘

Ilk et al.’s deconvolution algorithm using B-splines for well testing is improved. Deconvolution computation process is kept in the level of integral. A technique of piecewise analytical integration is adopted. The success of the deconvolution computation can be guaranteed. The deconvolution computation speed is largely enhanced.
