Abstract
Description
technical field
[0001] The invention relates to the technical field of oilfield automation equipment, in particular to an online continuous detection method and system for the water content of wellhead output fluid. Background technique
[0002] In the production process of oil wells, the water content of the oil well output fluid is an important indicator. At present, the main method is manual sampling and testing, which takes up a lot of time and labor for the on-site workers. In addition, due to the low sampling frequency, the output fluid cannot be accurately characterized. Water cut: At present, there are experimental products that can automatically measure water cut at the wellhead of oil wells, but the products in use need to be calibrated according to the production conditions before they can be applied, and online measurement is a transient, nonlinear, multi-parameter complex process , the flow pattern is complex and changeable, the interaction between phases is str...
