Abstract
The key to successful stimulating carbonate reservoir is acid uniformly distribute in entire reservoir, diverting acid technology could effectively solve this problem. In this paper, completed a series of single agent contrast tests, such as corrosion inhibitor optimization evaluation experiment, Fe stabilizer optimization evaluation experiment, diverting agent optimization evaluation experiment, then formed a novel formula of diverting acid system. Meanwhile carried out a series of performance tests of acid system, including acid apparent viscosity test, high temperature dynamic corrosion test, acid dissolving rate test, acid etched conductivity test, acid-rock reaction kinetic parameters test, diverting acid diverting performance test, the results show that this system could keep stability and present well diverting performance in high temperature conditions. Stimulated a well by using this novel diverting acid system, achieved acid uniform distribution in heterogeneous reservoirs, and stimulation ratio was significant.
