Since carbonate reservoirs develop pores and fractures have a complex formation pressure system, overflow even blowout seriously threaten the exploration development of these kinds reservoirs. According to characteristics fractured-vuggy reservoirs, field monitoring identification method for has been developed. This is based on top-down logic framework early identification, combined with optimi...

Based on the porous flow theory, an extension of the pseudo-functions approach for the solution of non-linear partial differential equations considering adsorption-desorption effects was used to investigate the transient flow behavior of fractured wells in shale gas reservoirs. The pseudo-time factor was employed to effectively linearize the partial differential equations of the unsteady flow r...

Daqing Oilfield is rich in low permeability reservoirs. In order to fully understand the development dynamics of ultra-low reservoirs, this paper takes as an example and studies productivity fractured horizontal Wells by numerical simulation method. The results show that decreases exponentially with decrease formation permeability. well increases fracture length spacing. With increase coefficie...

Carbonate rocks of the Triassic deposits South Mangyshlak basin are investigated in this paper for their boundary values, which important interpretation field geophysical data as well perforation and blasting. Based on lithological composition, classified either terrigenous or carbonate reservoirs. reservoirs found Middle strata containing volcanogenic dolomite limestone rocks. A complex type r...
