Abstract

Изобретение относится к области нефтяной и газовой промышленности и может быть использовано при текущем и капитальном ремонтах нефтяных и газовых скважин с аномально низкими пластовыми давлениями (АНПД), в том числе наклонных и горизонтальных, для фрезерования портов гидроразрыва пластов (ГРП) и многостадийных портов ГРП (МСГРП), и удаления песчаных и шламовых отложений посредством устройства, спускаемого в составе колонны бурильных или насосно-компрессорных труб (НКТ). Устройство для нормализации забоя и фрезерования портов гидроразрыва пластов содержит струйный насос с присоединенным к нему снизу уплотнительным пакером с каналом для отвода пассивной среды, при этом в устройстве выполнен обходной канал с возможностью отведения части активного потока в нижнее затрубное пространство, каналы диффузоров струйного насоса расположены в верхней части устройства и открыты по направлению к устью скважины, в пакере установлены уплотнительные манжеты, выполненные с возможностью вращения относительно оси устройства с сохранением герметичности при работе устройства. Способ нормализации забоя и фрезерования портов ГРП и МСГРП при текущем и капитальном ремонтах в скважинах, в том числе и горизонтальных с низкими пластовыми давлениями и АНПД осуществляют с помощью заявляемого устройства.The invention relates to the field of oil and gas industry and can be used in the current and capital repairs of oil and gas wells with abnormally low reservoir pressure (ANPD), including inclined and horizontal, for milling ports of hydraulic fracturing (fracturing) and multi-stage hydraulic fracturing ( MSHU), and removal of sand and sludge deposits through the device, the descent into the composition of the drill string or tubing (tubing). The device for normalizing the face and milling of the ports of hydraulic fracturing contains a jet pump with a sealing packer attached to it from the bottom with a channel for diverting the passive medium, while the device has a bypass channel with a possibility of diverting a part of the active flow into the lower annular space, the channels of the jet pump diffusers are located in the upper part of the device and open towards the wellhead, in the packer installed sealing cuffs made with the possibility of rotation about the axis roystva to sealingly during operation. The method of normalizing the face and milling of hydraulic fracturing and hydraulic fracturing ports during current and capital repairs in wells, including horizontal ones with low reservoir pressures and abnormally low-pressure formations, is performed using the claimed device.
