| Abstract: | In order to solve the problems in conventional acidification,such as fingering,small penetration depth and serious damage in high permeability reservoirs,a new intelligent acidification technique was proposed through theoretical studies and laboratory experiments.The acid system was mainly composed of viscoelastic surfactant and hydrochloric acid as well as a variety of additives,depending on the special properties of viscoelastic surfactant used for particular diversion,gel breaking,fluid retarder,and at t... |
