Study on the Stimulated Reservoir Volume Technology in Tight Carbonate Reservoir

摘要

In the development of carbonate reservoir, it usually uses acid fracturing to improve the production. Because of the limitation of, the production rates from the wells are very low. Based on the "stimulated reservoir volume" which is used in the development of unconventional reservoirs, combined with the characteristics of tight carbonate reservoirs, in the early stage with low viscosity liquid, large pump scheme, small size proppant and pulse type sand to form complex fracture network. In the later, with high viscosity liquid, high sand rate, large size proppant, and continuous type sand to enlarge the stimulated volume and conductivity. Based on the experimental evaluation, the fracture design was optimized, and it will provide a reference for the stimulation of tight carbonate reservoir.
