Abstract:

Aimed at the gas injection scheme design influenced by the reservoir characteristics,platform environment and
process conditions in offshore tight reservoirs,and so on,the response surface method“D – Optimal”is introduced to the
design of the WAG flooding process. Based on the representative gas flooding scheme and the statistics analysis of their
results,the prediction models and response surface for the recovery ratio index and gas injection time,water/gas ratio,cycle
injection plugins were presented,and the optimization design of the gas flooding parameters was investigated. The results show
that the work efficiency and quality of the low permeability reservoir gas flooding design in offshore has been improved.
