摘要
高凝原油析蜡点不仅是地面工程设计中的重要参数,也是油藏工程应用中确定合理注水温度的关键指标。文中列举了国内外8种析蜡点测试方法在海外某高凝油田A中的应用,分别筛选出满足地面管输工程和油藏工程应用的析蜡点。结果表明,显微观测法的测试结果最高,在地面管输工程应用中最为保守;地层条件下含气原油析蜡点明显低于地面原油析蜡点,应作为合理注水温度的确定标准。
Wax appearance temperature (WAT) of high pour point oil is an important parameter which can characterize wax precipitation. Also it is a key index of water temperature determination in reservoir engineering application. In this paper, eight measurements are used to determine the WAT of an oilfield in Africa. The WAT met the ground pipeline engineering and reservoir engineering application is selected. The result shows that compared with other methods, cross polar microscopy (CPM) is a conservative method that measures the temperature wax crystals first appeared in a sample. On the other hand, the WAT of live oil under the cnndition of the reservoir is lower than that of dead oil, which can be used for the design of reasonable water injection temperature.
