Annotation:
The article describes the technology, developed by the authors of the article, for removing liquid "plugs" from the bottom of gas condensate wells, which consists in a combination of two technical solutions – lifting of the product flow through concentric lift columns and pumping of the liquid phase by a bore-hole pump. The methods applied to remove the fluid from the well bottom at Pyakyakhinskoye field are considered, technological limitations are identified and solutions on the operational mode optimize of the gas condensate fund are proposed. The possibility of pumping liquid from the gas condensate wells bottom of the Pyakyakhinskoye field using well down pumping equipment was technically assessed.
