EOR Technology Improvement and Its Further Development for Daqing Oil Field during "10th 5-Year-Project"

In this paper,the optimization design technique in Class I oil layer,comprehensive adjustment technique,production technology,testing technology and surface technology for polymer flooding have been summarized.The development strategy for Class II oil layer with the application of polymer flooding was put forward,and the polymer flooding behavior in field was analyzed.The knowledge about ASP flooding mechanisms has been further studied,and the research on national produced surfactant for ASP flooding has been greatly improved with the commercial production of surfactant.The results for the pilot tests of ASP flooding were obvious,and further commercial tests would be done based on the results.The main problems for EOR technology in Daqing Oil Field during the "10th 5-Year-Project" were analyzed,and the further development for EOR was established in this paper.
