Open publisher page 54 citations

Abstract

Abstract The chemical screening and chemical formulation studies were discussed in this paper, and the pilot test results as well for the ASP combination flooding pilot test in Karamay EZ District. Also the designing strategies of the ASP process were included in this paper. The ASP pilot test started from August 21,1995 with the beginning of NaCl brine pre-flush in order to condition the reservoir, then followed by ASP slug and Polymer slug. The post-water injection was applied after the designed chemical injections. The 24%OOIP incremental oil recovery was achieved in the whole test area with about 25%OOIP incremental oil recovery for the central production well.
