Dissolvable Rubber Frac Plug Sealings for Oil Drilling
Dissolvable rubber materials are essential to modern oil & gas extraction operations. Bright's innovative rubber material is the ideal choice for downhole components such as frac plug sealing elements and o-rings.
Applications and features: The soluble rubber cylinder 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.
Characteristic advantage:
1, Independent research and development, filling the domestic soluble rubber cylinder blank, low cost, stable product performance.
2, The rubber cylinder is soluble, and is completely soluble in the reverse drainage liquid without residue.
3, After dissolution, the wellbore will form a fully-on diameter. Production logging can be carried out in the later stage of production.
4, The compressive strength of high strength soluble metal reaches 70Mpa, which meets the sealing requirements of fracturing construction.
5, Can completely eliminate the risk caused by drilling and grinding of coiled tubing and save construction time and cost.
6, Not restricted by the length of the coiled tubing, unlimited number can be entered (according to customer needs).
The situation of the Dissolving test in the laboratory: Put the rubber cylinder into a high temperature resistant container and fill it with tap water and put it into a water bath pot with a constant temperature of 90 degrees. After three days, the surface of the rubber cylinder becomes rough and soft, 5-7 days began to dissolve, and the cartridge dissolved into a paste after 10-15 days.
Application situation:The materials developed by our company have been used normally in many oilfields, The solvable rubber cylinder was successfully lowered into the target layer with the soluble bridge plug and the fracturing effect was good. The dissolution of the rubber cylinder was verified by the operator and dissolved completely without residue.
