Description

Изобретение относитс  к способам очистки от нефти песка, извлекаемого при добыче нефти в процессе эксплуатации скважин .The invention relates to methods for refining oil from sand that is extracted during oil production during well operation.

Цель изобретени  - повышение чистоты продукта.The purpose of the invention is to increase the purity of the product.

Пример. Пластовый песок, содержащий 0,08 мас.% нефти, промывают в течение 30 мин 0,5%-ным раствором НЕ, массовое соотношение песка и водного раствора 1:2.Example. Formation sand containing 0.08% by weight of oil is washed for 30 minutes with a 0.5% solution of HE, the mass ratio of sand and aqueous solution is 1: 2.

Результаты опытов представлены в таблице .The results of the experiments are presented in the table.

По известному способу получают продукт с минимальным содержанием нефти, равным 0,003 мас.%. Эффективность очистки 96,4%.By a known method, a product is obtained with a minimum oil content of 0.003% by weight. Purification efficiency of 96.4%.

Таким образом, предлагаемый способ позвол ет увеличить эффективность очистки песка от нефти.Thus, the proposed method allows to increase the efficiency of cleaning sand from oil.
