Well gravel fill sand during the operation, accurate measurement of the amount of sand injection is difficult, the low degree of automation, to carry out the Note sand gravel fill based on acoustic sensor measurement technology research. The article describes a method of gravel fill Note sand, Note sand sand wall collision signal characteristics; non-contact ultrasonic sensor measurement Note the amount of sand, and note the amount of sand based on DSP technology signal acquisition and signal processing systems, real-time monitoring of the injection fluid volume and note the amount of sand gravel fill process. Trials to test the feasibility of the measurement method, the system is easy to operate, high degree of automation, t accuracy reaches a certain height.
