| Abstract: | At formation pressure coefficient over 1 0, conventional water base drilling fluid can be applied for underbalanced drilling so as to tackle fluid leakage problem and cause less damage to reservoir. Technical parameters and application results are discussed by taking Well T401,Tarim Basin as an example. |
