鄂尔多斯盆地低渗透油田注水开发的调整与优化

Adjustment and optimization of water injection development of the low-permeability oilfields in Eerduosi Basin

根据鄂尔多斯盆地成功开发的主要特低渗油田——安塞、靖安、华池油田长6、长3油层的储层特征及开发实践,提出了改善特低渗油田注水开发效果的注采参数、注水方式优化及调整技术,从而达到提高单井产量及最终采收率,降低开发投资和生产成本,以提高整体开发效益的目的.

Based on the development practices and formation characteristics of Chang 6 and Chang 3 of main low permeability reservoirs in Ansai, Jing'an and Huachi oilfields, Eerduosi Basin, some techniques for optimizing and adjusting injection projection parameters and water flooding ways are put forward to improve the results of water flooding development, single well production and final recovery factor of super low permeability oilfields. They can reduce development investment and production cost, and can finally enhance whole development benefits.
