Steam-injecting pipes of the heavy oil thermal recovery are always operating in high temperature and high pressure, corrosion, fatigue and creep are prevalent in the steam-injecting pipes which make the pipes be liable to fail. The paper considers the influences of the operator, the maintenance, the environment and the operation, and establishes the risk assessment system of the steam pipeline of the heavy oil thermal recovery by the Grey Principle.
