Study On Heterogeneous Phase Transfer System Of B Oilfield

In the B oilfield,the contradiction between internal and interlayer is obvious and the permeability ratio is high.With the development of oilfield,flooding agent flowing caused by the strong reservoir heterogeneity and the presence of large pore lead to the difference of chemical flooding.Although the operation of traditional flooding has achieved good results,there are still some problems such as high injection dose and high pressure.Therefore,carrying out the research of heterogeneous online adjusting drive technology for expanding swept volume of injected fluid,improving the oil displacement efficiency and development effect of B oilfield has a very important significance of realizing the dynamic flooding and enhancing oil recovery in favor of the reservoir characteristics of B oilfield and limited space of offshore platform.According to the actual demands of development and geology characteristics of reservoir beds,the flooding system of B oilfield is selected through the laboratory determination.Ascertaining and optimizing the composition of heterogeneous system by evaluated the continuous phase and dispersed phase;Forming the heterogeneous system of B oilfield by evaluating the performance of plugging and oil displacement by indoor core simulating test finally.
