GB T531 Shale Gas Dissolvable Rubber

90 Degree KCL liquid dissolvable rubber compound for packer cup

Applications and features::The soluble rubber packer can be divided into compression type and expansion type, which is applied to unconventional oil and gas fields, multi-stage perforated bridge plug joint completion Wells, ultra-deep Wells, remote development Wells and depleted oil reservoirs. The rubber cylinder can be dissolved in clean water at a certain temperature. The higher the temperature is, the faster

the speed of the dissolution is. This fills the blank of the domestic soluble rubber cylinder, and reduces the production cost. The material has been used normally in oil fields in Xinjiang and southern Sichuan, and the usage is close to 8000 pcs.

Characteristic advantage:

Independent research and development, filling the domestic soluble rubber packer blank, low cost, stable

product performance.

The rubber packer is soluble, and is completely soluble in the reverse drainage liquid without residue.；

After dissolution, the wellbore will form a fully-on diameter. Production logging can be carried out in the later

stage of production.

The compressive strength of high strength soluble metal reaches 70Mpa, which meets the sealing requirements

of fracturing construction.

Can completely eliminate the risk caused by drilling and grinding of coiled tubing and save construction time and cost.

Not restricted by the length of the coiled tubing, unlimited number can be entered (according to customer needs).
