Experiment study of formation variation in heavy oil thermal recovery
Method: Physical simulation has been carried out under different thermal recovery condition of temperature, pressure and operation time. Tendency of rock, water and water property changes under thermal recovery condition is analyzed by rock mineral identification, organism geochemistry oil property analysis and numerical stimulation reservoir sensitivity evaluation technique by mineral identification and thermal dynamics geochemistry of reaction between hot fluids and rock. Purpose: To recognize formation damage mechanism, study reservoir protection measures of thermal recovery and to improve thermal recovery development effects. Result: material migration-chemistry reaction coupling model has been established, numerical simulation soft ware has been developed and has been applied in simple mineral and reservoirs samples, the law of mineral solution, precipitation and erosion has been summarized, the thermal recovery effect on reservoir material composition has also summarized Conclusion: mineral solution and precipitation, reservoirs fluids composition can be predicted, measures of improving thermal recovery effect has been put forward.
