The experimental result shows high-temperature heat pipe fin has the better characteristic and is not restricted by sonic limit, entrainment limit and capillarylimit during the operation process.
Because of these characteristics, the pressure measurement system with capillary tubing can be used without depth limit and can measure the downhole pressure continuously without time limit.
由于这些特点,毛细管测压系统在使用时无深度限制,可以不受时间限制连续地测取井下压力。
