Abstract


Crude oil industry moisture content is an important test parameters . The parameters were measured for oil extraction , such as dehydration and gathering of great significance . Since two-phase or multiphase flow flow characteristics than the one-way flow not only much more complex , and there is a phase interfacial effect and the relative velocity , resulting in online testing more difficult. Accurate measurement of the moisture content of crude oil is constantly exploring international study. Microwave technology has good real-time , good reliability, high precision , anti-interference ability , and ease of operation uses no radiation damage , etc., easy to implement without loss , real-time , on-line rapid measurement , application prospect. So choose the microwave transmission method to online measurement of crude oil water content . Based on the principle of microwave transmission , designed for the measuring range of 0 to 100% water -line measurement of water content of crude experimental apparatus . The main research work is as follows : 1. Analysis and comparison of methods currently used line detection principle and the advantages and disadvantages of microwave transmission method elaborated principles and characteristics . (2) analysis of the dielectric constant and dielectric constant factors , to establish a microwave transmissive gas-water multiphase flow Physical and mathematical models and formulas derived moisture . 3 Analysis of the multi -sensor information fusion technology , the use of improved BP neural network , the establishment of influencing factors and microwave multi-parameter measurements moisture neural network prediction model . 4 Design a system based on microwave transmission method of gas-water -line moisture measurement of multiphase flow experimental apparatus . Include: microwave detection devices , microwave measurement pipe section , the new gravity water separator, static mixing phase , signal acquisition system, power cycle devices and accessories.
