【摘要】 连续管水平井钻井可保证储层钻遇率、增大储层泄油面积、提高开发效率,可解决水合物储层埋深浅造成的常规水平井钻井轨迹控制难的问题。构建了深水天然气水合物水平井钻井井筒温度场计算模型和天然气水合物生成模型,得到了深水天然气水合物水平井钻井井筒温度压力分布,建立了天然气水合物生成温度压力分布图版,得到了天然气水合物生成的温压范围。更多还原

【Abstract】 Coiled tubing horizontal well drilling can ensure reservoir drilling rate,increase reservoir drainage area,improve development efficiency,and solve the problem of conventional horizontal well drilling trajectory control caused by shallow hydrate reservoir. The temperature field calculation model and gas hydrate formation model of deep water gas hydrate horizontal well drilling wellbore are constructed,the temperature and pressure distribution of deep water gas hydrate horizontal well drilling wellbore is obtained,the temperature and pressure distribution chart of gas hydrate formation is established,and the temperature and pressure range of gas hydrate formation is obtained.更多还原
