Piezometric technique with capillary tubing is a kind of technique which transfers downhole pressure onto surface by taking nitrogen as the pressure transfer medium, tests the pressure, and then based on it reckons the pressure at the piezometric depth.

毛细管测压技术是以氮气作压力传递介质，将井下压力传递到地面，在地面完成压力的测试，再将所测压力推算至井下测压深度处压力的一种测压技术。

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。
