The Research Of Jinghe Reservoir Stimulated Reservoir Volume(SRV) Technology

In order to fulfill the needs of E`Nan Jinghe tight sandstone reservoir in continuing to increase the yield,we fully researched the adaptability and technology characteristics of stimulated reservoir volume(SRV),completed the research of SRV of Jinghe reservoir purposely.Through the rock dynamic experiment,we concluded the relative permeability? porosity and rock dynamic parameters.Meanwhile,we made an analysis on adaptability of SRV from various aspects,such as Reservoir property?brittleness?In-situ stress size and orientation?characteristics of Natural fracture development ?Reservoir sensitivity.On the basis of this research,Jinghe reservoir was discovered that permeability and porosity are low,but brittleness is high.There are many natural fracture in the reservoir,mainly dominated by high Angle and horizontal cracks.Its horizontal stress difference is small.This reservoir has the conditions of implementing SRV.On this basis,we established the finite element model to optimize the perforation parameters from the aspects of reducing fracture pressure and cave friction.In view of induced stress field,we calculated the distance of opening and turning natural fracture,then optimized the cluster spacing.Finally we optimized the SRV operational parameters.Through reaching,we demonstrated the adaptability of SRV of E`Nan Jinghe tight sandstone reservoir,designed a set of SRV technical method and optimized parameters.This can be used in guiding the development of Jinghe reservoir efficiently.
