Abstract

Abstract: Numerical simulation is an important method to verify the results of indoor test of miscible flooding，to analyze the sensitivity and to optimize the injecting program.Results of the numerical simulation of reservoir fluids and miscible simulation of long-tube and well group are consistent to the indoor experimental results.The result of numerical simulation shows that the MMC，composed of GPL and gas with a mol proportion of 37.1∶62.9,can be miscibled with crude oil under the condition of reservoir，which is coincident with the result of indoor experiment.Based on the analysis of pressure，temperature and sensitivity of injecting parameters，WAG is recommended in sector Ⅳ( half a year).The miscible plug will be cumulatively up to 0.1PV,and production is performed in the layer of Ⅰ,Ⅱ and Ⅲ and layer Ⅱ and Ⅲ are injected.

Key words: rich gas, miscible flooding, fluid simulation, simulation of miscibility, sensitivity
