Title: Method for rapid isolation of absorbing zone in well with high-flow inter-compartment flow from superhigh stratum saturated with strong brines, and packer equipment for implementation thereof
Inventor: VAKHROMEEV ANDREJ GELIEVICH

Abstract: FIELD: oil, gas and coke-chemical industries. 
     SUBSTANCE: invention relates to oil and gas industry, in particular, to methods of isolation of zone of hydraulic fracturing of reservoir and catastrophic absorption in conditions of inter-zone overflow from fossil material to absorbing stratum. To implement the method for rapid isolation of the absorbing zone in the well, the depth of the roof of the absorbing formation and the depth of the absorption zone are determined from geophysical survey data. Drillable packer equipment is lowered into the well on a geophysical cable with installed load for 20 kN disconnection in excess of its own weight. When lowering below the interval of high-pressure refractory formation due to creation of additional load on the booster unit due to pressure drop between developing and absorbing formation cable disconnects from packer equipment. Packer equipment, carried away by liquid flow, is accelerated and reaches bottomhole, where at impact of head part of weighted tapered weight with booster unit to bottom face, transformable packer is deformed due to speed of movement along well bore and blocks flow of liquid into absorbing formation. Water-swelling packer additionally isolates the absorption zone, and over time, the salt precipitated from the brine additionally isolates the absorbing formation, providing further transition to works on insulation of the high-pressure refractory formation by the casing string. Packer equipment comprises transformable packer with sealing for geophysical cable, water-swellable packer, weighting cone with acceleration unit equipped with tail unit. Packers are rigidly interconnected by a rod. Weighted taper with acceleration unit is connected with transformable packer by flexible coupling. 
     EFFECT: achieving the technical result - bringing the well to the design bottomhole and improving the reliability of the open wellbore attachment by the casing string and providing accident-free oil and gas recovery.

Протезы кисти и предплечья содержат по меньшей мере три пальца, один из которых противопоставлен остальным пальцам. Тяговый протез пальца состоит из неподвижного основания, нижней фаланги, верхней фаланги, подвижного блока, тяги, коромысла и упругого элемента, предназначенного для разгибания пальца. Один конец нижней фаланги соединен с неподвижным основанием так, что нижняя фаланга может вращаться вокруг поперечной оси относительно неподвижного основания, а другой конец соединен с верхней фалангой. Ось подвижного блока закреплена на нижней фаланге. Один конец тяги закреплен на неподвижном основании. Тяга огибает подвижный блок так, что натяжение другого конца тяги приводит к повороту нижней фаланги относительно неподвижного основания. Коромысло соединяет неподвижное основание с верхней фалангой и упругим элементом таким образом, что неподвижное основание, нижняя фаланга, верхняя фаланга и коромысло образуют механизм шарнирного четырехзвенника. Достигается возможность скрытого расположения тяг в конструкции протеза для защиты их от механических повреждений, загрязнения и износа, уменьшения потерь от трения скольжения между тягами и деталями протеза, причем исключаются перегибы тяг в противоположных направлениях. 3 н. и 12 з.п. ф-лы, 3 ил.
