Research on preparation and evaluation of acid microemulsion system for near-well bore treatment in sandstone formation
Abstract
The paper presents some research results on preparation and evaluation of acid microemulsion system for near-well bore treatment in sandstone formation, droplet size and thermal stability of the microemulsion. The microemulsified acid is much less corrosive to steel than pure acid solution (mass concentration 12%). Results of microemulsified acid flooding test on core samples from Miocene and Oligocene of Bach Ho field are also presented in this paper.
