Abstract:

There are two types of dual porosity media: fracture-pore and fracture-vug, which displays quite different performance. The fracture-pore dual-porosity media are characterized by a “concave” on the well test curve, while the fracture-vug dual-porosity media are characterized by a straight line without a concave. The flow rate of fracture-pore dual-porosity media reservoir declines quite more rapidly than the fracture-vug dual-porosity media. The fracture-vug dual-porosity media reservoir is similar to single porosity reservoir in flow mechanism and production performance, so can be equivalent to single porosity reservoir.

Key words: late water flooding, reservoir pressure decline, degassing of crude oil, injection-production ratio, pressure build up, recovery ratio
