Numerical Simulation Research on Reasonable Production Time Limit Optimization of Advanced Water Injection in Low Permeability Oilfield

Abstract:

Based on the characteristics of low permeability, low pressure, poor effect of conventional waterflood development and low recovery efficiency in Chao Yanggou oilfield, advanced water injection is applied. Taking the Chang 10^th block of Chao Yanggou oilfield as an example, the research on reasonable production time and pressure limit of advanced water injection in low permeability oilfield are carried out using methods of numerical simulation and reservoir engineering. The result shows that the average permeability of the Chang 10^th block is 7.0×10^-3μm², the reasonable time of advanced water injection is about 6 months, and the recovery efficiency increases 2.26% compared with synchronized water injection. The successful application of advanced water injection development technology has some guidance on low-permeability oilfield development.
