摘要
利用时差法阐明井下超声波流量计的工作原理,对超声流量计由于系统、介质、油管内径、注水井、声路长、声路角的影响产生的误差进行分析,对水井测试具有一定的指导意义。
The working principle of downhole ultrasonic flowmeter is expounded by time difference method,and the error caused by systematic error,media,internal diameter of tubing,water injection well,long traveling distance and direction of sound is analyzed. It is the guidance for water well test.
