发明名称 OIL AND GAS PRODUCTION METHOD AND TOOL FOR IT
摘要 FIELD: oil-and-gas industry. ^ SUBSTANCE: invention related to oil-and-gas industry and can be used for porridge-like fluid production and for oil and gas residue extraction from worked out wells, and also when necessary and for normal wells oil recovery increase - vertical, inclined, horizontal, single zone or multi zone ones. Method includes installation of a production pump with pipes routing and well reservoir treatment, with heated fluid and depression. Heat the fluid in a dib hole, with it supply from a wellhead via tubes into the dib hole. Create depression by pumping fluid calculated part via jet pumps, installed over the reservoir, pumping the fluid form a bottom hole for depression creation. Execute calculation of the fluid volume, which pumped via jet pumps, according to condition to provide pumping capacity, which is equal of greater to volume of fluid leaving the bottom hole. When necessary to increase well's oil recovery rate, create in it two horizontal areas: in the reservoir and in the dib hole. Use dib well soil heat to heat up the fluid. ^ EFFECT: increase of product withdrawal factor. ^ 2 cl, 1 dwg
