Asphaltenes control in the oil wells

production systems over the years has been one of the main problems in the oil industry . Selected chemical factors controlling the dissolution of the asphaltenes in the specimens recovered from mass production systems was limited . Currently accepted methods for solving this problem Nzyrgzyln aromatic solvents , toluene and so on . This method requires the use of large amounts of solvents . The high frequency of this procedure should be done . In this paper the results of tests on oil fields and asphaltene control chemicals and laboratory tests to eliminate the use of chemical inhibitors, asphaltene precipitation and deposition of asphaltenesdescribes؟× Preliminary tests of power dissipation, the experiment started spreading asphaltenes in n-hexane . Some chemicals that promising results in asphaltene solubility and dispersion containing insoluble in hexane media have presented , for use in the oil fields or for additional test samples meet the current ore deposits have been selected؟×Sets the current test sample (core flow test apparatus) way to become familiar with the study of asphaltene precipitation and removal using chemical agents is presented .Sfaltynhay obtained from rock samples and production resources , this gives us theopportunity to select the best chemical treatment of asphaltene deposition.
