The Research on Improving the Efficiency of Injection-Production of the Lamadian Oilfield in Ultra-High Water Cut Stage

Abstract:

With the oil field developing, the water cut increased, gradually and the efficiency of injection-production reduced year by year. Since the water flooding of Lamadian Oilfield entered extra high water cut period, the distribution of flow flied become more and more complex. The distribution of remaining oil and ineffective circulation is complex. The existing of ineffective circulation led to the flooding efficiency reducing sharply and cost of crude oil per ton by water flooding increased. In order to control production energy consumption in the extra high water cut, the method of improving the efficiency of Injection-production is studied in the Lamadian oilfield. Through the analysis of injection-production status, the factors that influence the injection efficiency is studied. The distribution of ineffective circulation which seriously affects the efficiency of Injection-production is made clearly. According to the factors that influence the efficiency of injection-production, based on flow field characteristics of water flooding, the countermeasure to enhance efficiency of injection-production is put forward in order to reduce the energy consumption and cost of producing crude oil.
