Adjustment of infill in transition zone to improve oilfield productivity

Affected by the high viscosity of crude oil, large injection-production well spacing, poor injection condition, and low oil recovery rate, overall development effect transition zone is poor, besides, produced degree utilization thin layer makes have some potential excavation. Under condition that current conventional measures to improve block are not clear, it necessary further optimize system. Based on principle “Well pattern rules, Well spacing optimization, Injection-production perfecting, Facilitation adjustment”, combination thus optimized. This paper analyzes encryption adjustment tracking adjustment.
