Abstract

Abstract: Combined with the result of long tube test,the impact of injecting time,means and quantity of enriched gas miscible drive on the miscible effect is evaluated by the experiment of long core test.Under reservoir condition,the miscible fluids,composed of GPL and gas with their mol proportion of 36:64,are capable of being fully miscible with crude oil,and enhance the recovery rate of 15% compared with water drive.In terms of the injecting technical parameters,early injection of miscible fluids is favor of enhancing production rate,and WAG is propitious to controlling gas out.Injecting quantity of miscible fluids has a great impact on drive effect and differential pressure of sequent water drive,and it is advised to optimize injecting plug size of miscible fluids by means of numerical simulation in order to increase the economic benefits of miscible drive.

Key words: enriched gas, miscible displacement, long core, process parameters, effect
