基于超声波的泥浆密度测试技术研究
摘要
泥浆密度测试在石油勘探开发过程中占有极其重要的地位
但目前的测试方法往往是离线的
存在速度慢、不够方便等缺点.针对油田井下泥浆密度测量
研究了超声波信号的衰减特性.通过实验
建立了泥浆密度与超声波回波信号幅值间的关系
并给出其在1.0 g/mL至1.9 g/mL范围内的拟合曲线
通过实验样本验证了其可行性.
Abstract
Mud density testing has an extremely important position in the process of the oil exploration.The paper elaborates the attenuation technology of ultrasonic signal used in the mud density testing.The relationship between mud density and the amplitude of ultrasonic echo signal is set up and verified by experiment
and the fitting curve from 1.0g/mL to 1.9g/mL is given in the paper.
