Application Analysis of Chemical Flooding Technology in the Development of Tight Oil
摘要
This study explores the application of chemical flooding technology in the southern Ordos Basin to enhance tight oil reservoir development. Employing a multidisciplinary approach, we integrated field data, laboratory experiments, literature reviews, and reservoir simulations to comprehensively assess the effectiveness and economic viability of this technique. Reservoir characterization identified porosity and permeability ranges, while fluid property analysis elucidated oil and water viscosities across different temperatures. The investigation focused on the mechanisms of chemical flooding, particularly interfacial tension reduction and viscosity enhancement. Utilizing Eclipse and CMG software for reservoir simulations, we predicted significant improvements in oil recovery and reductions in water cut. Economic evaluations, including net present value (NPV) and return on investment (ROI), confirmed the project’s financial feasibility. Our findings demonstrate that chemical flooding substantially enhances oil recovery, reduces water cut, and offers a high economic return, positioning it as a promising strategy for tight oil development in the southern Ordos Basin.
