Study on Reasonable Injection-production Well Spacing and Well Pattern Deployment in Low Permeability Oilfield
Download as PDF
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.
