双压力振动管钻井液密度在线测量装置
A Dual-Pressure Vibrating Tube Type Device for Mud Density Measurement
摘要
Abstract
Mud density control plays a very important role in preventing downhole troubles.There are many factors affecting the online measurement of mud density,such as shaking of well site,mud flowrate and air trapped the mud etc.A serial dual-pressure vibrating tube type mud density measuring device has been designed by modifying the original mud density online test device,realizing the online measurement of mud density.Laboratory and field test showed that the modified dual-pressure vibrating tube type online mud density test device has high precision and high accuracy,with measurement error controlled in less than 0.003 g/cm3.In the working range of the device,the test results are not influenced by temperature and mud flowrate.关键词
