At present, the rapid development in recent years , despite the remaining oil research technology , in the understanding of the field at the same time has made considerable achievements , the delta distributary plain facies and delta front deposits based on polymer flooding , due to its channel sand body small scale, multi-layered , thin thickness , permeability is low , flat and vertical heterogeneity serious , the remaining oil is still very difficult . The past two years under the leadership of the leadership in the Oilfield Company , Sabei Development Zone for the fine work of polymer flooding in an orderly manner , formed at the same time supporting research and technology measures technical consolidated adjust gradually to the integrated, comprehensive direction of development , this study is in line with this thinking , through a detailed analysis of the static and dynamic information on the sub-layers , accurate description of the two types of oil layer thickness of reservoir internal distribution of remaining oil , find out the genetic types and characteristics of the two types of reservoir sand bodies , according to the reservoir utilized within the status of thick reservoir remaining oil, to identify the main factors affecting the distribution of the remaining oil , then supporting technology for tapping the potential of the different types of residual oil research targeted the largest increase in the degree of recoverable reserves , enhanced oil recovery . The risk is small , practical features , can also be synchronized with the most advanced mining technology development , has a good promotion prospects and development momentum in the Daqing Oilfield .
