Abstract
More than a third of the recoverable reserves of the Arlanskoye oil field are contains in the middle carbon sediments, which develop with pressure maintenance system. This sediments are characterized low filtration properties, high heterogeneity and natural fractures. For improving development drilled horizontal wells with multi-stage fracturing. Low filtration properties, excess fracturing pressure during injection leads to the autofracturing effect, which be dagger-like water breakthroughs ahead high-conducting channels-cracks to producing wells. For improving the efficiency and increasing the coverage of injection in low-permeability carbonate reservoir are used horizontal wells.
Materials and methods
Research of fracturing pressure according to hydraulic fracturing reports, creating fracturing pressure map, identification of the relationship between autofracturing effect in injection wells and increasing water-phase in producing wells, comparison of injection conditions in horizontal and directional wells.
