Abstract

Способ и устройство Юмачикова эксплуатации самоочищающейся скважины, включающий очистку от механических примесей части (А) пластовой жидкости в самоочищающемся фильтре, установленном между протектором электродвигателя и входным модулем центробежного насоса, подачу центробежным насосом очищенной части (А) пластовой жидкости в струйный насос, установленный над центробежным насосом, отбор струйным насосом части (Б) пластовой жидкости проходящей мимо центробежного насоса и содержащей механические примеси, подъем смеси части (А) и части (Б) пластовой жидкости по насосно-компрессорным трубам на устье, самоочищающийся фильтр снабжен фильтр-элементами выполненными в виде усеченных конусов, полым корпусом с фланцами, шлицевым валом, отличающийся тем, что объем очищаемой части (А) пластовой жидкости, перекачиваемой центробежным насосом, равен 70% дебита скважины, объем неочищаемой части (Б) пластовой жидкости равен 30% дебита, при этом часть (Б) дообогащается механическими примесями, смываемыми потоком пластовой жидкости с фронтальных поверхностей фильтр-элементов и поступающими через боковые отверстия, выполненные на кожухе самоочищающегося фильтра, в затрубное пространство между устройством и обсадной колонной, по затрубному пространству часть (Б) поднимаясь в сторону устья поступает в струйный насос, фильтр - элементы самоочищающегося фильтра в количестве не менее двух штук последовательно и коаксиально расположены на полом корпусе между фланцами, перекрывая кольцевой зазор между корпусом и кожухом самоочищающегося фильтра, при этом кожух также коаксиально установлен относительно корпуса, размер ячеи на Method and device of Yumachikov’s operation of a self-cleaning well, including cleaning of mechanical impurities of part (A) of the formation fluid in a self-cleaning filter installed between the motor protector and the input module of the centrifugal pump, supplying the cleaned part (A) of the formation fluid to the jet pump installed above the centrifugal pump pump, selection by a jet pump of part (B) of formation fluid passing by a centrifugal pump and containing mechanical impurities, raising the mixture of part (A) and part ( ) reservoir fluid through the tubing at the mouth, the self-cleaning filter is equipped with filter elements made in the form of truncated cones, a hollow body with flanges, a spline shaft, characterized in that the volume of the cleaned part (A) of the reservoir fluid pumped by a centrifugal pump is 70 % well flow rate, the volume of the uncleaned part (B) of the formation fluid is 30% of the flow rate, while part (B) is enriched with mechanical impurities washed away by the flow of formation fluid from the front surfaces of the filter elements and the incoming through the side openings made on the casing of the self-cleaning filter, into the annulus between the device and the casing, part (B) ascends to the mouth towards the mouth through the annulus, and the filter - the elements of the self-cleaning filter in an amount of at least two pieces are sequentially and coaxially arranged on the hollow housing between the flanges, overlapping the annular gap between the housing and the casing of the self-cleaning filter, while the housing is also coaxially mounted relative to the housing, the mesh size is
