FUNCTION:
——leak proof isolation of casing mandrel zones;
——flow string isolation in order to install temporal or permanent cement plugs;
——remedial cementing with purpose of liquidation of behind-the-casing flow of produced water.
DESIGN FEATURES:
——non-return valve allowing isolating material to penetrate to sub packer space and to prevent back flow of this material;
——easy setting with use of setting tool UP by differential pressure generation in tubing;
——grippers are protected from premature setting;
——short length of drillable section.
ADVANTAGES:
——simple design;
——easy reliable setting of packer in deep, directional and deviated wells;
——good drillability of the used materials.
SPECIFICATIONS:
——operating environment: oil, gas, gas condensate, produced water;
——maximum operating environmental temperature 100°С*.
