Abstract:
Pore, fracture and vugs consist of the main reservoir space of carbonate reservoirs. Fracture is an important seepage channel. The causes, fracture geometry, filling and situation will further affect the stress sensitivity of reservoir. By means of contrast experimentation, researching the stress sensitivity of natural fracture and artificial fracture samples, with and without solids invasion fracture samples, with and without acid etched fracture samples, connected and disconnected double vugs. The results including 8 groups show that the average stress sensitivity coefficient are respectively 0.64,0.75,0.52,0.18,0.73,0.50,0.33 and 0.73, and the degree of stress sensitivity is respectively medium to strong, strong, medium to strong, weak, strong, medium to weak, weak and strong. It showed that the stress sensitivity of natural fracture stronger than artificial fracture, solids invasion and acid etch strengthen the stress sensitivity, the connection of double vugs weaken the stress sensitivity of fractured samples.
