Abstract
Theoretical and practical basis of oil optical properties was described in the paper. Results of numerous laboratory experiments of density, viscosity, optical density D and coefficient of light absorption Cla of oil probe were analyzed in various oil and gas provinces in the Russian Federation. The brief description of an oil sample photocolorimetry researches procedure was reported. The statistical data processing was conducted that consist in estimation of a mean-square deviation, variance of the deviation and variation coefficient of oil coefficient of light absorption. It fixed up correlative dependency between density and coefficient of light absorption, also between viscosity and coefficient of light absorption.
It showed up description, international and Russian oil ranging, where oil is permeated with a hyperviscosity and an average density. The oil typification in character of density and mean-square deviation of Cla approximation was conducted, 3oil classes were selected with sufficiently high value approximation validity – light (with density ρ 920kg/m 3 ). In character of viscosity and mean-square deviation of Cla approximation 3oil classes were selected with sufficiently high value approximation validity – low-viscosity (with viscosity 1 30mPa·s).
Came up with the decision to improve of oil optical researches and optical method control of oil field development. The mobile device hook up of automated optical properties measurement and processing of oil on the well mouth was established by oil density, viscosity and coefficient of light absorption that let enhance precision and reliability of optical method field-geological control of oil field development and get reliable field-geological information in real-time.
