Technologies of separated layer water flooding: an overview

Water flooding is one of crucial measures for long-term high and stable productions of oilfield development. The historical course of water flooding technology is described, and then brief review of the present status and development of the research are summarized in this paper. Based on that, the exist problems and the technical challenges for present water flooding operation is analyzed and then give birth to the development and management of water flooding technology. The overview of flooding future affords benefit for application of water flooding, on site operation management and science and technology development.
