Abstract

Abstract: In this paper, the influences of well pattern and space on ASP flooding in Daqing oilfield were investigated by using nu-merical simulator GCOM. Well patterns, including 4-spot, 5-spot, 7-spot, 9-spot, inverted 9-spot, straight row and inclination row in the simulation, and well spaces ranging from
200 to 300m were studied in this simulation. The numerical simulation results indicated that the 5-spot is the most favor-able well pattern for ASP flooding in Daqing oilfield, while the 7-spot is the worst well pattern. The well space between in-jector and producer should be smaller than that of 300m at such
simulation conditions as injection volume ranging from 0.1 to 0.3 PV and injection pressure less than 13.5 MPa. As a result, in-fill drilling will give good future for industrial application of ASP flooding in Daqing oilfield.

Key words: combination drive, numerical simulation, performance analysis, well pattern and space
