When size of choke line is not variable, the first and second circulation rate increases with well depth increasing.
对于某一特定尺寸的节流管线，第一循环周及第二循环周的最大流量随着水深的增加而增加；
A leaking choke line has added delay to tests designed to make sure the well can tolerate the pressures engendered by a firm seal on the top.
一条阻塞线的泄漏导致测试延期，该测试旨在保障油井可以承受顶部严密封死的压力。
Additional flow rate (AFR) method can overcome this problem beautifully by inject a kind of light and thin fluid into choke line to drop its pressure loss.
附加流速法通过向节流管线内注入轻质的附加流体降低了节流管线的压降，可以很好的解决上述的压井难题。
