Abstract:

There are two measuring methods of stress sensibility of reservoir rocks: constant-pore-pressure changing-confining-pressure procedure and constant-confining-pressure changing-pore-pressure procedure. Constant-pore-pressure changing-confining-pressure procedure is simple and easy in operation, while constant-confining-pressurechanging-pore-pressure procedure is complex and difficult in operation. The pore-pressure stress-sensibility curve by
constant-confining-pressure changing-pore-pressure procedure can be used to evaluate the stress sensibility directly.However, the confining-pressure stress-sensibility curve by constant-pore-pressure changing-confining-pressure proce-dure must be transformed into pore-pressure stress-sensibility curve through effective stress of rocks for evaluation ofstress sensibility. The evaluation results of the both methods are same. The constant-confining-pressure changing-pore-pressure procedure does not have any advantage and should be abandoned. The stress sensitivity of reservoir rocks is only related with stress sensitivity coefficient and porosity and not related with pressure values of experiments, so the experimental pressure should not be raised to quite high level in order to avoid high pressure risks.
