摘要:
为了准确预测深水气井测试管柱内的井筒温度分布,根据能量守恒原理及传热学原理,建立了深海气井在普通测试流程及在隔水管内循环注入常温水工况下的井筒温度预测模型。模拟计算结果表明,隔水管循环注入常温水对测试管柱的温度有一定的影响,当水深大于200 m时循环液温度与海水温度基本一致,循环时可使隔水管环空温度降低从而增大水合物生成风险。因此,水深大于200 m的深水气井不宜采用隔水管循环注水。本文研究成果对于深水气井隔水管循环注液测试具有指导意义。
Abstract:
In order to accurately predict the wellbore temperature distribution in test string of deepwater gas wells, a wellbore temperature prediction model for deepwater gas wells under normal testing process and under riser circulating normal temperature water injection was established based on the principle of energy conservation and heat transfer mechanism. Simulation results show that circulating normal temperature water injection to riser has some impact on the temperature of the test string. When the water depth exceeds 200 meters, the temperature of the circulating fluid is basically same with that of the sea water, and the circulation may reduce the temperature of riser annulus, which will increase the risk of hydrate generation. Therefore, circulating water injection to riser is not recommended for deepwater gas wells over 200 meters. The research results of this paper are of guiding significance for the test of riser circulating liquid injection in deepwater gas wells.
