Sealing Device

Устройство герметизирующее УГРХ

Sealing Device is designed to seal the annulus in liner of oil and gas wells during hydraulic fracturing. Setting of sealing unit is performed into adapter male section in order to protect parent string from high pressure whereby from damage during hydraulic fracturing.

Features and benefits:

  • Does not require scraping at the device installation site
  • No limits for device RIH speed
  • Quick seal assembly replacement after use
  • НDoes not require geophysical tie while device setting

Setting of the Sealing Device is carried out in the male section of the adapter, thereby the device protects parent column from high pressure during fracturing.
