Description
Известные сп() ликвидации иесчаных пробок в 1луби1111О- асосных скважинах недостаточно эффективны ir вызывают остановки в добыче нефти.Known sp () elimination of sand plugs in 11111O-suction wells are not effective enough and cause stoppages in oil production.
Предлагаемый еиособ ликвидации песчаных пробок устран ет )jeдостаткн примен емых способов, так как ирием глубинного насоса оборудуют телескопическим хвостовико% и производ т откачку пульпы насосом при поддержании посто нного уровн жидкости в скважине методом подлива нефти в затрубиос простраиетво.The proposed method for eliminating sand plugs eliminates the methods used, since the submersible pump is equipped with a telescopic tail and used to pump the slurry with a pump while maintaining a constant level of fluid in the well by adding oil to the side of the well.
Суи-1ность предлагаемого способа ликвидации иесчапых пробок в глубипио-иасосных скважинах состоит в том, что размывку и извлечение пробки ведут при посто нном уровпе жидкости в скважине, откачива песчаную пульпу по насосным трубам в огстойр ую емкость. После очистки от песка жидкость поступает обратно в затрубное простра«ство. Способ осуществл етс при помощи «телеекопического хвоста, спускаемого на приеме глубинного насоса в скважину на уровень пробки.Sui-1ness of the proposed method of eliminating sand plugs in deep-well wells consists in washing and removing the plug at a constant level of fluid in the well, pumping sandy slurry through the pump tubes into a stopper. After sanding, the liquid flows back into the annular space. The method is carried out using a telescopic tail descending at the inlet of a submersible pump into the well to the level of the plug.
«Телескопичеекий хвост по мере вымывапи песчаной пробки опуекаете под действием собственного веса до тех пор, пока она полностью ие будет вынесена циркул ционной жидкостью на поверхность.“The telescopic tail as you wash out the sand plug jams under its own weight until it is completely removed by the circulating fluid to the surface.
«Телескопический хвост состоит (см. чертеж) из наружной подвижной трубы /, в которую входит труба 2, соединенна с приемом глубинного насоса, и на конце которой укреплена направл юща муфта 3. Муфта 4 с сальником 5 и нажимпа гайка 6 обеспечивают герметичное передвижение трубы / по трубе 2."The telescopic tail consists (see the drawing) of an external movable pipe / into which pipe 2 enters, is connected to the intake of a submersible pump, and at the end of which a coupling sleeve 3 is fixed. Coupling 4 with the gland 5 and pressing the nut 6 provide hermetic movement of the pipe by pipe 2.
