The microwave transmission method has been selected to measure the moisture content of crude oil based on a lot of water holdup measurement literatures at home and abroad and the comparison of advantages and disadvantages which the different measure methods have.

In this paper, the line measurement of moisture content of crude oil is selected by the microwave transmission method.

Study of ultimate temperature in low temperature transportation of water cut oil;

Firstly, the article study the character of pipeline transporting about heavy water cut oil.

On a loop conduit experimental installation,the pressure drop of watercut crude oil(WCCO) of Daqing 1st oil production factory with flow improver(FI) DODE added flown through a perforated tube 62 mm in diameter and 900 mm long,a pumping unit tube valve(TV) 55 mm in diameter,and a pumping unit pillar fill valve(PFV) 30 mm in diameter succesively is measured at 45℃.

Biodemulsifier HRB-4 is selected for dehydrating watery crude oils of Chunliang, Shengli, from 7 biological reagents of HRB series.

In order to improve measurement accuracy and widen measurement range for water content in crude oil, a computation method based on the electrical measurement of multiple modes was proposed in this paper.

This paper measured some parameters that affect the measurement of the water content of crude oil at wellhead metering device using the multi-sensor technology and processed these parameters using the K-means clustering,then the prediction models for water content in crude oil based on the methods of BP neural network and CPN networks are presented.

In conventional demulsifier used in the field,dewatering in crude oil is slow,water content of crude oil and oil content in sewage a.

It is hard to measure the water content of crude oil precisely because the dielectric constant of crude oil varies greatly when displacing agent and emulsion breaker are injected.
