Abstract
Measurement of Water Content of Crude Oil Using Quartz Crystal Microbalance
Highlights
A quartz crystal microbalance (QCM) is a mass balance of quartz crystal resonator (QCR) under converse piezoelectric effect, which was first developed in the early 1960s
The theoretical density of the well-configured glycerol solution was calculated using the volume water content formula, the viscosity η of each solution was measured with a rotary viscometer (NDJ-1), and the theoretical frequency shift Δft was calculated using Eq [12]
This paper presents a systematic method to accurately measure the water content of crude oil by using the liquid phase detection technology of a QCM in oil exploitation
Summary
A quartz crystal microbalance (QCM) is a mass balance of quartz crystal resonator (QCR) under converse piezoelectric effect, which was first developed in the early 1960s. In the past few decades, the QCM has been widely used in various sensor research applications, from initial thin-film thickness detection[1,2] to electrochemistry,(3,4) biomedicine,(5,6) materials science,(7,8) environmental monitoring,(9,10) and many other fields. QCM detection technology has been used in the petrochemical industry. The water content of crude oil is an important technical indicator in oil exploitation. Its accurate measurement plays an important role in improving the production efficiency and predicting the development life of oil wells, and in the secondary high-efficiency exploitation of old wells.
