METHOD FOR SAMPLING OIL AND OIL PRODUCTS FILMS FROM WATER SURFACE AND DEVICE FOR IMPLEMENTATION THEREOF Russian patent published in 2016 - IPC G01N1/10 

FIELD: oil and gas industry; measurement technology.

SUBSTANCE: invention relates to analytical research of films from oil and oil products and can be used for determining composition of oil and oil products in natural water reservoirs. Device is made in the form of hollow cylinder 1 with plug 6 from inert material and tip 4, in which there is precision valve 3. Sampler has a developed inner surface with inner section diameter and height ratio of 1:3-1:10. On the outer surface of the sampler there are marks 2 for measuring volume of the collected sample. Before sampling the sampler is annealed at temperature of 500-1,000 °C for 5-20 minutes. Then it is cooled to ambient temperature and lowered into the analyzed medium. Fixed sample volume is sampled. Then water phase is drained slowly with speed of water surface movement inside the sampler of 10-300 mm/min and the film is deposited on the inner surface of the specific area of the sampler, is analyzed for content of organic substance.

EFFECT: higher accuracy of analysis, possibility of performing quantitative analysis of organic substances in the taken sample, as well as possibility of sampling in field conditions.
