Application of Low Carbon Acid Compound Deplugging Technology

Article Preview

Abstract:

Formation damage is mainly due to the reduction of reservoir energy and the increase of flow resistance from reservoir. According to this theory, low carbon acid compound deplugging technology is introduced to improve well productivity. The compound blocking remover which will be used is consist of low carbon acid, rudimentary fatty acid and surfactant and so on. Where geological condition a large volume of carbon dioxide gas generate, through increasing the reservoir energy, removing all kinds of reservoir choke, the well productivity will increase effectively.
