双U型管式高温高压流体密度传感器
Double U Tube-type Hi-temp & Hi-pressure Liquid Density Sensor
摘要
Abstract
Introduced is a new downhole double U vibration tubes liquid density sensor. The sensor consists of double U type tubes and electromagnetic exciting device. The two U type tubes form a single way flow channel by tube assembled on the base. The electromagnetic exciting device generates power to excite and maintain the resonance of the U type tube. The U tube is manufactured with low TEC,high pressure-resistant, and corrosion-resistant alloy material to meet the requirement of sensor application environment. High temperature material is used in the electromagnetic coil and magnetic core of exciting device. Test results show that the sensor performance meets the design requirements and can be used in downhole fluid density measurement. Now the sensor has already been used in exploration well in Bohai oilfield.关键词
