FUNCTION:
——used in packer assemblies as top packer;
——used for longtime autonomous (without connection with tubing) isolation of a required interval of the production string;
——development and operation of oil, gas and injection wells;
——acidizing;
——formation testing;
——casing leak searching;
——oil string isolation from exposure to working medium of wells in service;
——other maintenance and repair works and technical operations realization of which requires pressurization above and under the packer.
DESIGN FEATURES:
——setting and releasing method is mechanical;
——tight connection of casing and mandrel;
——without bottom anchor gear;
——upper anchor is mechanical;
——fixation in operating position.
ADVANTAGES:
——possible to transmit turning torque to pipe string or mechanisms set under the packer;
——versatility, simple design;
——capable of autonomous operation, without tubing string;
——non-use of sealing elements in upper anchor provides hermetic sealing with high reliability under continuous service;
——rotation of the mechanism and pressurizing is not required;
——multiple setting of packer for one round trip;
——easy fault-free setting of packer in deep, directional and deviated wells.
SPECIFICATIONS:
——operating environment: oil, gas, gas condensate, produced water;
——maximum operating environmental temperature 100°С*.
