PACKER PGPM1 The packer of type PGPM1 is intended for increasing quality of productive formation insulation when fixing the bores in order to prevent cross flows and annular ingressions of formation fluids during cement mortar setting, The parker is lowered in the bore as the part of casing column and installed in the set interval. The construction of packer PGPM1 has a protection system against premature operation of increased reliability. To activate the packer PGPM1 the drop of casing annulus and tubing pressure is not necessary, so, it significantly widens the area of its usage, i.e. the packer may be installed in upper intervals and in so called uncemented sections of bore. In addition, the improved construction of the parker valve unit provides a possibility to activate several packers successively installed at one production string. The distinctive aspect of packers PGPM1 lies in existence of repair and prophylactic additional setting of packer. The system is activated during hydraulic pressuring of cemented casing pipe, it provides a possibility to adjust the sealing ability of packer during exploration or underground repair of bore by dosed increasing of liquid volume in the seal element. Main elements of packer PGPM - upper sub; - packing unit; - protection unit of packer against premature actuation; - valve unit; - lower sub.

RETRIEVABLE PACKER PGE-1

The retrievable packer PGE-1 is a full bore, high performance and installed compressively packer: it is used for squeeze jobs, acid treatment, hydraulic formation breakdown or well test. The packer is equipped with plunger anchor shoes, three element system of packer setting and a release valve of bigger diameter for reliable and accident-free operation. The packer PGE-1 may be lowered independently or with a recoverable temporary plug. Performing repair works in the conditions of high pressure, the packer is kept in the place of seating using the integral hydraulic system of engaged grooves. The pressure which is necessary for operation of the system is not taken off directly from the pump and compressor pipes, but from sealing elements, it prevents its clogging by mud and cement. The parker PGE-1 has an integral sluicing system, providing a possibility to compensate pressure difference in the packer during its removing and providing protection of hydraulic grooves during operation and easier circulation, it has an automatic lock for seating and placing in the transportation position in the bores. The packer may be operated "clockwise" and "anti-clockwise".

RETRIEVABLE TWO-SECTION PACKER FOR SELECTIVE WORKS SPM

The selective integral packer is used for insulation of perforation with a specified length while performing stimulation operations and testing of bores. The assembly is lowered in the bore with a switched off bypass element above or below perforation. Rotation of pipes NKT to the left side results in closing of the bypass and engaging with the string by lower slips. The required weight of pipe, assigned to the packer, is packering the space by rubber elements. The assembly may be pressure-tested in the non-perforated string. The packer is placed in the transportation position, by raising the pipe and revolving it to the right, in order to close the circulation valve and to install lower grooves in the transportation position. If necessary, the bypass element may be opened for circulation of liquid through the packer. Reinstallation of packer in the incumbent intervals may be performed by raising the tool and by its loading to start operation once again. To install the packer in the underlying interval it is necessary to remove the packer and to install it in the transportation position for moving it down.
