Paraffin Deposition Test and Phase State Simulation for Dalaoba Condensate Gas Reservoir
The condensate gas reservoir of paraffin in Dalaoba is a kind of special and complex gas reservoir.High content of paraffin for condensate gas reservoir in Dalaoba and the deposition of paraffin seriously affect the production and safety to bring about greater economic loss.The method with combination of laser method and on-line filtering method for PVT high-pressure physical property shall be employed,and the simulated deposition method for paraffin precipitation phase state shall be established,therefore,the deviation between the simulated prediction results and experimental value for the paraffin precipitation point in Dalaoba is between 0.2°C~3.5°C to meet the precision requirement on engineering computation.
