| 摘 要： | 对有井下节流装置的气井动态分析的研究,首次提出采用井口采集数据,从井口向井底计算井筒内的压力温度综合值的计算方法.考虑井筒径向传热,建立了等截面井筒内压力温度预测的数学模型.计算出口处的马赫数的值,判别节流嘴内的流态,进而逆向求节流嘴上游的各参数.对宝1井进行了实例计算,计算结果显示节流嘴对整个井筒内的压力温度的影响,认为节流嘴入口温度高是避免水合物形成的主要原因. |

| Abstract: | In this paper,a numerical method to describe the distribution of pressure and temperature in the well bore with downhole-choke from wellhead to bottom was established.Those factors that the radial heat transfer of the wellbore and different heat transfer medium in annular are considered.The Mach number in the outlet of the choke is calculated,and the flowage can be decided.Based on the preceding numeration,pressure and temperature of upstream can be solved.The basic data of Bao No.1 are used for history calculation.The change of the temperature and pressure in different depth of well are showed.It thought the higher temperature in the inlet of choke is one of the prime reasons of avoid hydrate. |
