| 摘 要： | 对辽河油田杜32块起稠油油藏进行提高蒸汽吞吐开采效果的综合研究，从机理、室内实验、数值模拟等方面研究氮气、溶剂辅助蒸汽吞吐开采技术。筛选出高效溶剂，测试驱油效率，根据数值模拟结果，提出注1／3溶剂段塞加氮气辅助蒸汽吞吐开采可以使采收率增加4．0%，增油成本为436元／t，为超稠油油藏的有效开发提供了理论依据。图3表3参23

| Abstract: | The Xinglongtai oil formation of Du32 block in Liaohe Oil field, eastern China, is a typical super heavy oil reservoir. The LH 5 solvent developed in recent experiments has the property of effectively dissolving asphaltene and resin, with a good effect of reducing the viscosity, and good disperse in oil. Numerical simulation shows that the result of Huff and Puff with the solvent and nitrogen is better than that of conventional Huff and Puff. If the economic OSR is 0.25 in single cycle, one well can produce for 8 cycles, production time will be 920d, the cumulative oil will be up to 12,180t, the cumulative OSR is 0.54, the average daily oil production will be 13.2t/d, the recovery will be 14.3%. The economic analysis shows that if the price of the solvent is 2500 yuan (RMB)/t and the price of the nitrogen is 1 yuan(RMB)/m 3 , the cost of the incremental oil will be 436 yuan (RMB)/t. |
