利用短路效应减低环状掺水集输流程能耗方法
摘要
Abstract
The influence of water temperature and system energy with different water flux in conventional cyclic water gathering process were analyzed based on the properties of conventional cyclic water gathering process, and the key question of energy saving was attained. A novel cyclic water gathering process was introduced according to the thermal short circuiting theory of borehole heat exchanger in theground. Energy conservation models of different systems were proposed. And the calculations of different systems were studied by using models. The results show that with the water flux increasing, the temperatures of cyclic process decrease; and the temperatures fluctuating extent of cyclic process were more severe with the water temperature of union station increasing. With the water temperature increasing, the system energy increases, and the water flux decreases; the curves intercrossing of system energy and water flux exist with water temperature increasing. The key question of energy saving was established in conventional cyclic water gathering process, with the oil arrival temperature of cyclic process and measurement station being higher than union station, considering the oil arrival temperature of u-nion station. The system energy and water flux in the novel cyclic water gathering process were less than conventional one with the same conditions. And with the oil arrival temperature decreasing, the cyclic process energy was 20% less than conventional one. The conclusions play an important role in improving the cyclic water gathering process in oilfields.关键词
