Results of experimental determination of Yaregskoe field degassed oil rheological features are given in the article. Modern methods of visco-elastic and thixotropic properties research are described and results of these methods application while abnormal oil research are shown. As a result an improved data of Yaregskoe field oil is obtained and there is a recommendation to extend a number of enhanced oil recovery methods, including physicochemical and wave methods application.
The most promising method of oil production in the mode of forced fluid withdrawal is the use of electric centrifugal well pumps. Transfer of a well into the mode of forced fluid withdrawal leads to deterioration of downhole equipment operating conditions. At the same time the parameter of failure interval decreases. The main factors reducing the productivity of electric centrifugal well pumps are revealed and the ways of their compensation for the conditions of Samotlor oil field are offered.
