Recently, Daqing Oilfield Co., Ltd., Harbin Institute of Technology and Daqing Petroleum Institute jointly undertaken by the project "deep treatment and resource utilization of oily wastewater in oil" passed the identification of experts organized by the Science and Technology Department of Heilongjiang Province. It has been identified that the overall level of the research achievement has reached the international advanced level and the research results have far-reaching significance for the post-high water cut development and sustainable development of Daqing Oilfield.
The project takes oil-contaminated water as the research object and aims to meet the technical requirements of the injection water quality control needed for the development of the oilfield. The project is suitable for the production of ultra-low permeability oil-producing water and ASP flooding, Corresponding backwater injection water quality control indicators required processing equipment and processing technology to achieve its full recovery of sewage injection, to achieve the resource utilization.
