摘要：

This paper analysed the sensitivity of high pour point oil reservoir, fluid property, the law of water flooding with different temperature and cooling zone in the bottom of the injection well. The results showed that: water salinity, Ph value and water injection rate affected water flooding results. Temperature of high pour point oil reservoir had a great impact on the efficiency of water flooding. When temperature was lower than wax precipitation temperature, the wax precipitation affected the efficiency of water flooding. Water injection wells temperature test of Shen 84-An 12 block showed that strata existed cold injury at present. If the reservoir temperature droped too fast, you should give due consideration to improve the injected water temperature, making the formation temperature higher than the wax precipitation temperature, and improved oil field development results.
