Abstract

Изобретение относится к добыче нефти и может быть применено для улавливания песка при добыче нефти штанговыми скважинными глубинными насосами. Задачей изобретения является не допущение попадания песка в зазор между плунжером и цилиндром насоса и предотвращение выхода из строя штанговой подвески и насоса. Поставленная задача решается тем, что в устройстве для улавливания песка в нефтяной скважине, установленном на штанговой подвеске выше глубинного насоса, включающем ловушку для песка, наружный диаметр которой меньше внутреннего диаметра НКТ, и дифференциатор давления, находящийся выше ловушки, ловушка для песка обеспечена тремя роликами, установленными в гнездах, открытых под углом 120° на передней и задней крышках, прикрепленных с помощью штифта на ловушку.The invention relates to oil production and can be used to trap sand during oil production by sucker rod pumps. The objective of the invention is to prevent sand from entering the gap between the plunger and the pump cylinder and to prevent failure of the rod suspension and the pump. The problem is solved in that in the device for trapping sand in an oil well mounted on a rod suspension above a deep pump, including a sand trap whose outer diameter is smaller than the inner diameter of the tubing, and a pressure differentiator located above the trap, the sand trap is provided with three rollers mounted in slots open at an angle of 120 ° on the front and rear covers attached with a pin to the trap.
