| 摘 要： | 关于井涌余量,前人论述较多,但有些概念尚不一致,因而影响其计算及正确运用。本文根据井控实际情况,提出了压井井涌余量的定义,并把它与临界泥浆增量、井口许用套压、裸眼地层破裂压力统一起来,从而系统地给出了关井、司钻法压井、工程师法压井、超重泥浆法压井等各种情况下的井涌余量计算公式和方法,便于现场工程师使用。

| Abstract: | This paper has presented a new definition of kick tolerance and unified it with the critical pit gain, allowable pressure of BOP and fracture pressure of bore hole, and thus given the calculation methods and formulas of kick tolerance under conditions of using shut-in wethod etc. systematically. The new definition and its calculation methods are very convenient for drilling engineers to use in the field. |

| Keywords: | Bottom hole pressure Well control Kick tolerance Estimation of fracture pressure of formation |
