3.
Based on what had been done previously in the aspect of pressure losses across perforation and gravel pack, the paper presents a new formula to calculate the pressure losses across perforation and gravel pack,and calculates the skin factor through the introduced popular equation of radial flow.
在以往对砾石充填井压降分析的基础上,给出了一种以普通径向流方程为基础计算井筒附近收敛流动和射孔-砾石充填段的压降,再根据完善井与非完善井压降之间的关系,求出表皮系数的方法。
补充资料：砾石填充液
分子式：
CAS号：
性质：砾石填充作业中，用来携带砾石或砂粒并将其运送到井下预定位置的液体。这种液体要求具有一定的黏度，不含有可能伤害地层及砾石层渗透率的物质，能较快降解，使砾石柱在井下能保持最佳的填充密度和过滤能力。
