| Abstract: | This paper analyzed carbonates reservoirs’ geology in Daniudi gas field，proposed diversion acid technology basedon the reservoir transformation status and difficulties. The diversion acid mechanism were analyzed from both theoretical andexperiments perspectives. Diversion acid system’s performances were studied by experiments on rheological properties，acidrockreaction kinetics，diversion and broken plastic performance. At last，the application of diversion acid technology in A wellis a breakthrough of exploration and development in Daniudi Gas Field. |
