Abstract

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

Key words: Daniudi Gas Field, tight carbonatite, horizontal wells, diversion acid, diverting device mechanism
