Research on water driving state evaluation and adjustment technology based on streamline

The general reservoir engineering method is the injection volume and production between regular injection-production well pattern (five-point method, seven-point nine-point etc.), geometric average calculation or kh method. accuracy of results low it difficult to reflect political enemy dynamics heterogeneity correctly evaluate water characteristics development characteristics. Problems injection, distribution efficiency are not solved. We can intuitively understand dynamic flow fluid in underground by using oil-first device technology, combined with basic principles engineering, a hydraulic evaluation proposed. Using this many variables such as drainage area oil well, flooding velocity, swept Wells be evaluated quantitatively, effect field accurately. According analysis factors wire, corresponding adjustment measures taken make dominant wire weaker weak stronger, finally achieve purpose improving recovery rate.
