Application of soft sensor based on SVM on estimation of water cut of crude oil

In this paper, the working principle of sensor based on conductance which is suitable for the high water cut instance is expounded, and estimated performance of the simply empirical formula method by simulation is researched. The reason for inac- curacy of the original estimate method is analyzed, and the idea for improving the estimate accuracy by soft-sensing technique is proposed. Soft sensor model on water cut of crude oil based on SVM is established. The result of simulation research proves that soft-sensing technique is effective in improving estimate accuracy of water cut of crude oil.
