DEFINITION METHOD OF WATER CONTENT AND SUMMARY CONTENT OF METAL-CONTAINING MICROELEMENTS IN OIL OR OIL-PRODUCTS Russian patent published in 2010 - IPC G01N27/06 

FIELD: oil-and-gas production.

SUBSTANCE: definition method of water content in oil and oil-products in flow of pipeline includes measurement of complex electric conductance of oil and oil-products at two frequencies: at frequency f₁ and at working frequency f₂ (f₁<f₂) then it is implemented temperature correction of measurable parametres, it is defined ratio of η complex quantities of electric conductances at two different frequencies, it is defined mass fraction metal-containing microparticles δ and by value of ratio η it is implemented identification process, and by value of ratio it is implemented elaboration of type of oil and oil-product, and sum content of water in oil or in oil-product is calculated by gauge model, corresponding to particular type of oil or oil-product.

EFFECT: increasing of determination accuracy of water in oil and oil-products and ability of receiving of stationary gauge model by types of oil by deposit or mix oils.
