| 中文摘要:针对CCSD-1井的钻进方法、井身结构和泥浆体系，通过2000 m取心钻进的实施情况和采集的钻井液性能检测数据，采用数理统计和回归分析的方法，优选了卡森流变模式，计算CCSD-1井不同井深的循环压降。结合现场的生产实际，分别测定了螺杆马达、液动潜孔锤和双管取心钻具的循环压降，最后，确定了钻井液循环通道各部分的压力分布。 |

| Abstract:To counter the drilling technology, bore well structure and mud system, Casson rheology pattern was optimized and circulation Pressure Drop of CCSD-1 well in different depth was calculated by applying mathematical statistics andregression analysis with 2000m cored drilling practice and data collection of drilling fluid performance testing. Circulation Pressure Drop of PDM and Hydro-percussive hammer for rotary-type double tube core barrel tool were respectively tested. Pressure loss distribution of circulation fluid in each pipe passage was decided in conclusion. |
