Abstract: In recent years，wellhead real-time sanding monitoring developed abroad is a real-time monitoring tool for oil
well sand production with high precision. Based on SandQTM sanding monitoring system and optimizations of its matching
technology，a 3D sound wave conduction finite element program is developed with the help of FEPG system，and then wall
thickness of bent pipe is simulated and optimized in sonic testing which suggests that the thickness of pipe should be between
5 mm to 10 mm. Then a finite element model for analyzing the time when near wellbore percolation reach to stabilization
is developed. Wellhead testing program is also optimized. The research shows that，in the case of loose sandstone reservoir
with high permeability，the percolation near wellbore could reach to stabilization in 24 hours after the adjustment of oil well
production system. According to the well site practices，the frequency of production system adjustment for oil well should
be 1 time per 24 hours. The system has been tested，and the result shows that it has a great applicability for oil wells with
electric submersible pump Christmas tree and regular pumping unit. It also has a high applicability and high testing accuracy
for oil wells with low-viscosity product，but it has a low applicability for oil wells with high-viscosity product whose dynamic
viscosity is more than 1 824 mPas.

Key words: real-time monitoring, sanding, sound wave testing, monitoring program, field test
