Analysis and Evaluation of Development Effect in Typical Polymer Injection Block of Daqing Off Field

This paper has carefully collected and processed the development and adjustment programs, the inspection well data, the interpretation data of flooded layer in three typical blocks, which have been completed polymer injection in Sazhong region of Daqing oilfield. Based on detailed geological research, reservoir control degree of well pattern and well spacing was analyzed for the three blocks. The producing dynamics and response characteristics of polymer flooding were fully tracked and analyzed in the polymer injection block and the improved central well..And recovery efficiency of polymer flooding was fully evaluated with the method of displacement performance, stream tube method and normalization method in three industrial polymer injection blocks. By using injection profile, numerical simulation, inspection wells and flooded layer interpretation data after polymer flooding, the potential and distribution of remaining oil after polymer flooding were analyzed. This paper evaluated and analyzed the development effect of polymer flooding comprehensively and systematically aimed at guiding the follow- up polymer injection block to be developed rationally and effectively as well as providing technical data for further improving oil recovery after polymer flooding.
