The invention relates to a method for using foam to repeat using the foam non-balance drill well, which comprises: directly guide the foam at the well open into the sealed cycle system, to eliminate contained rock bits; then using foam pressurizing system to pressurize it to make the pressure reach needed value; then enter it into inlet tube beam, to use it repeated and reduce the cost. And the invention can solve the pollution problem that discharging foam. In addition, said foam sealed cycle system comprises: foam bits removing system, foam pressurizing system, and foam detecting system. The invention has the advantages that: (1) it can avoid foam break process to overcome the defects of physical and/or chemical method that affect foam quality and need foam again; (2), it has simple process and easy operation.
