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;
For the abundant of noise in testing oil well depth with sound wave, it is difficult to locate the reflected sound wave.在用声波测试油井油液面深时,反射声波受到大量杂波干扰,给接箍波和液面波的定位带来了极大的困难。
During developing well depth measurement system for mud logging unit, it directly affects the accuracy of well depth measurement whether winch sensor signal processing is rational or not.井深测量是综合录井最为重要的参数之一,在录井仪井深测量系统研制过程中,绞车传感器信号处理是否合理,将直接影响井深测量的精度。
