CONSTITUTION:A drill bit 2 is operated for a drilling process with muddy water supplied to the inside of a drilling well, thereby forming an oil or gas well. When the drilling well encounters a mud escape part 5 and muddy water pressure drops, chemicals are filled into the mud escape part 5, composed of 10 to 99 weight parts of a hydrophilic urethane polymer and 1 to 99 weight parts of a water soluble solvent hard to dissolve in a mineral oil having no active hydrogen. According to the aforesaid system, the mud escape part 5 can be closed.
