The well testing technology is an important method to evaluate oil-gas reservoir dynamics, well completion efficiency and effect of measures, identify geological characteristics/parameters of reservoir. According to the issue that regular well testing technology can not evaluate carbonate formation fracture-hole scale and some other information, we developed our method and the breakthrough of well testing theory of fracture-hole reservoir has been preliminarily realized. Based on the preliminary research, the Project further develops and perfects the theory and method of fracture-hole type well testing.

Method of fracture-hole reservoir well testing considering gravity effect: According to well-hole-fracture model; well-hole-fracture-hole-fracture model; well-fracture-hole-fracture model and well-fracture-hole-fracture model, combing dimensionless parameters by pressure and derivative simulation, time and pressure simulated value can be obtained. We can get inversion of formation and fracture-hole parameters by pressure recovery curve.
