摘要: 文中推导了关井条件下天气然溢流许可不膨胀上升高度的计算式以及在许用套压下控制天然气溢流膨胀上升时应放泥浆量的计算式。

Abstract: The formulas for calculating the allowable rising height of gas kick under the shut-in well condition are derived in this article. Under adefinite casing working pressure, the volume of mud that should be released when a gas kick is allowed to expand rising up the annulus is also discussed here.
