摘要
探讨孔内压力计算公式，定义了孔内压力降低系数。计算出给定条件下不同孔深的压力、压降系数、泡沫泥浆密度，并作出曲线图，求出降压系数极大值及其适应孔深。
Bore-hole pressure calculation formula is discussed,bore -hole pressure drop factor is defined Press-sure,pressure drop factor and foam mud density are calculated at different depths in the given condition;a curve is drawn ;maximum pressure drop facto applicable depth are determinded.
