从浮球在井筒液体中的受力情况出发,通过分析浮球在油、套管中的运动状态,导出了计算浮球上升(或下沉)速度,球和流体的运送时间及浮球运移的方程;探讨了浮球从井口输送到射孔段的输送条件,得出了浮球坐封到炮眼上及保持浮球稳定坐封于炮眼上的条件及其相关公式。计算结果表明,该方法可用于指导现场浮球暂堵酸化的设计与施工。
Based on the force situation of the floating ball in the wellbore fluid, by analyzing the movement state of the floating ball in the oil and the casing, the calculation of the rising (or sinking) speed of the floating ball, the delivery time of the ball and the fluid, The transfer equation of the float from the well head to the perforation section was discussed. The conditions for setting the floating ball to the blasthole and keeping the floating ball steady on the blasthole were obtained, and the related formulas were obtained. The calculation results show that this method can be used to guide the design and construction of temporary floatation acidification in the field.
