The Technology Research Of The Middle Of Saertu Dense Pattern Oil Reservoir Comprehensive Description

At present, the daqing oilfield waterflooding oil recovery is 44.4% after infilled adjustment ,recovery degree is 29.7%. Still exist great exploitation potentiality. However reservoir comprehensive description technology have made rapid development, the result of oilfield development work in determining period played a greater role. To meet the remaining oil reservoir characterization, determining period, development, design, the need for each aspect development foundation. Based on the daqing oilfield in the Middle Of Saertu as the study area. The Middle Of Saertu of dense pattern reservoir comprehensive description technology was studied.Based on the domestic and foreign relevant technical documents and achievements in research area, extensive investigation and research basis for related research work on site, and summarization, describes the study of geological characteristics and sedimentary characteristics, and introduced the two kinds of reservoir heterogeneity characteristics and the three methods of analysis of the characteristics of remaining oil distribution and application of rock physics research thin layer in the poor water flooded layer, river water flooding characteristics of reservoir sandbody research methods, and dense pattern based on the logging information of two kinds of geological modeling methods, namely the three-dimensional modeling method and phased in reservoir modeling method, the results can be applied to new drilling of the reservoir parameters interpretation work, and rich and deepen the reservoir characterization techniques, the theory and the practice has strong applicability and necessity. This thesis research is perfect in reservoir description method and technology, comprehensive and promotion for determining value, can produce period, especially the reservoir potential residual provide reliable basis.
