在钻孔射流抽水工作中，正确选择工作泵和射流元件，直接关系到抽水效果的好坏。因为在射流抽水系统中，不论地面工作部分，还是井下工作部分，都与射流元件的形态紧密联系着，只要选择并调整好射流元件，便能达到抽水的预期效果。然而，用优选法反复调试井下的射流元件，以选取最佳形态，仍是费工耗时的工作。如何用计算方法在室内确定数据，在地面一次调好射流元件，这是射流抽水工作中的一个重要问题。
In drilling jet pumping work, the correct choice of working pump and jet components, directly related to the pumping effect is good or bad. Because jet pumping system, regardless of the ground part of the work, or downhole work, are closely linked with the shape of the jet components, as long as the selection and adjust the jet components, you can achieve the expected pumping effect. However, it is still a time-consuming and labor-intensive task to repeatedly test downhole jet components by the optimization method to select the best shape. How to use the calculation method to determine the data indoors and adjust the jet components on the ground at one time is an important issue in the jet pumping work.
