Abstract
Способ изоляции притока пластовых вод в пологих и горизонтальных скважинах, оснащенных в продуктивных пластах хвостовиком-фильтром, разделенным на участки сплошными и фильтровыми секциями с установленными на каждом участке сплошных секций пакерами и соединенным с лифтовой колонной, диаметр которой больше или равен диаметру хвостовика-фильтра, заключающийся в том, что, по мере подъема уровня воды в продуктивном пласте, последовательно, без глушения скважины, производят спуск на гибкой трубе через устьевой герметизатор в хвостовик-фильтр перфорационный заряд, создают перфорационные отверстия под пакером в зоне притока пластовых вод, извлекают гибкую трубу, затем спускают на ней пакер-пробку с технологическим инструментом, герметизируя трубное пространство над зоной притока пластовых вод на участке сплошной секции, и закачивают на поглощение в обводненный участок пласта под пакер-пробку технологическую жидкость для оттеснения пластовой воды, заполняют эту зону тампонирующей смесью, после чего гибкую трубу с технологическим инструментом приподнимают над пакер-пробкой для закрытия циркуляционных отверстий в пакер-пробке, и извлекают из скважины, которую затем, после демонтажа устьевого герметизатора, запускают в работу с эксплуатацией пласта выше пакер-пробки.A method of isolating formation water inflow in shallow and horizontal wells equipped with a filter shank in productive formations, divided into sections by continuous and filter sections with packers installed in each section of continuous sections, and connected to an elevator column whose diameter is greater than or equal to the diameter of the filter liner, consisting in the fact that, as the water level rises in the reservoir, sequentially, without killing the well, descend on a flexible pipe through the wellhead sealant into the liner p is the perforation charge, create perforations under the packer in the zone of formation water inflow, remove the flexible pipe, then lower the packer plug with the technological tool on it, sealing the tube space above the zone of formation water inflow in the area of the continuous section, and pump it into the flooded area for absorption formation under a packer plug technological fluid to displace produced water, fill this zone with a plugging mixture, after which a flexible pipe with a technological tool is lifted above the packer plug minutes to close the circulation openings in the packer tube, and removed from the well, which is then, after removal dock wellhead, launch into operation with the operation of the reservoir above packer plug.
