Satellite Oilfield in High Water-Cut Stage New Composite Displacement System Research

Abstract:

Satellite oilfield is in high water cut production period, many reservoirs flooded, or great changes after long-term water injection pore structure, heterogeneity is more serious. These strata to high-dose slug of deep processing, plugging agent dosage, only cheap oil displacement system has use value. Therefore, urgent need to develop a economic and effective system of new type displacement, especially for high permeability, high permeability and deep processing of large hole formation. A grade sodium soil clay particle displacement agent used with HJ - 708 can enhance the blocking effect, and can prevent or reduce the particle migration. This article by viscosimetry screening reagents with clay particles oil displacement agent and the added amount and the kinds of grade A sodium plus the amount of soil to optimize indoor experiment and A series of oil displacement system for optimization and evaluation. High pressure model of indoor experiments show that the new type of oil displacement system blocking rate reached more than 90%, on the basis of the original recovery efficiency increased by seven percent.
