【摘要】 在压井过程中,要求井底压力能够保持不变,并使井眼系统的压力保持平衡关系。为此本文详细推导了工程师法压井的立管总压力、环空压力和地面套压变化规律的计算,使工程师法压井进一步完善,现场应用更方便。更多还原

【Abstract】 In kill operation, it is required to keep the downhole pressure stable and the well bore pressure balanced. For this reason, the author derives in detail the formula for calculating, the changes of total stand pipe pressure, annular space pressure and easing pressure in kill operation by "engineer method", making it further perfect and convenient to apply at the well site.更多还原
