Aiming at problem that in oil well perforation pressure test

acceleration effect of piezoresistive sensor affects precision of test under hydrostatic pressure condition

a correction method is developed for the piezoresistive sensor at pressure environment.This method improves experimental apparatus

simulates static hydraulic act on sensitive surface of sensor

uses pendulum hammer as acceleration shock excitation source to get relationship of piezoresistive sensor and acceleration response

and thus obtain mathematical model for sensitivity of acceleration effect to correct perforation pressure value in measurement.
