Abstract

Aiming at reservoir conditions and geological characteristics of low permeability oilfield, this paper elaborates on factors influencing rational injection-production well pattern, determination principle of well pattern spacing, selection principle of reasonable well pattern, how to optimize well pattern and well layout, and finally optimizes reasonable injection-production well spacing and well pattern deployment method. Good results have been obtained by experiments.
