A well testing way to shorten closed time effectively
Keywords:
Convolution pressure build up, Liquid build upAbstract
Influenced by effect of bore hole afterflow,a long closes time is needed for pressure build up test in low permeability reservoir. Using testing technology of annulus fluid level to build up and pressure at well bottom to build up synchronously and its correspond interpreting method can shorten the tested time over 30 percentages.
