Research and Application of Horizontal Well''''s Acidizing Technology in Tarim Oilfield

The acidizing treatment is selected firstly because of being polluted and damaged to horizontal section in super deep horizontal wells .The paper discusses the feature of the super deep well's completion and analyses the main cause of pollution to horizontal section in Tarim oilfield.On base of that,the research and optimum designing for acid formulation is conducted and the study and actual application for acid technology with sand matrix is competed.That has gained a result of increasing production and a good economic and social benefit.
