| 摘要 | A method of treating production fluid in a wellbore includes deploying a capillary string into the wellbore. The capillary string has a plurality of injection valves. The method further includes pumping treatment fluid through the capillary string and into the wellbore. The injection valves have a cumulative set pressure greater than or equal to a hydrostatic pressure of the treatment fluid. | ||
