FIELD: oil and gas industry. ^ SUBSTANCE: invention relates to oil-producing industry, particularly to systems of calculation and preparation of oil. Method of oil calculation in oil extraction system includes oil collection from several suppliers (from several directions), preparation of oil, measurement of the amount and quality of crude oil. Before discharge of crude oil there are selected one or several directions from all arrival directions of oil to the oil preparation unit. In each of directions it is measured amount of crude oil, arrived in a flow. Flow is transferred into turbulent and divided for two flows - major and minor flows. In minor flow it is measured amount of selected crude oil, it is directed to the small-powered oil preparation unit, it is measured quality and amount of stock-tank oil at output of small-powered oil preparation unit. Then stock-tank oil in minor flow is mixed to major flow of the same direction. ^ EFFECT: increasing of measurement accuracy of amount of arriving oil while cost reduction of instrumentation technology and equipment. ^ 2 dwg |
