摘要

针对石油井下射孔压力测试中

承受静液压力的状态下压阻式压力传感器的加速度效应影响了测试精度

提出了在加压环境下进行传感器的加速度效应修正的方法。该方法改进了试验装置

模拟产生静液压力作用于传感器敏感面上

利用摆锤锤击作为加速度冲击的激励源

获得了压阻传感器与加速度的响应关系

从而求得加速度效应灵敏度数学模型来修正实测中的射孔压力值。

Abstract

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.
