| Abstract: | In view of large filter loss and limited penetration distance in acid-eroded fractures in vuggy carbonatite oil reservoir at Tahe Oilfield,three working fluid systems,i.e.high temperature gelling acid system FRK-V180,variable-viscosity acid system KMS-50 and surface crosslinked acid system SRGE,were selected through optimization,and the viscosity,solution ratio,acid-rock reaction kinetic parameters,H＋mass transfer coefficient,proppant carrying capacity and gel breaking property,etc.of the three acid fluids were studied,which has provided the technical support for the realization of deep penetration modification in vuggy carbonatite oil reservoir at Tahe Oilfield. |
