HAL DA-1井是中原油田5001钻井队在孟加拉国承包英国凯恩(Cairn Energy PLC)公司的1口深层高压天然气定向井。完钻井深4519.7m,最高钻井液密度2.2 g/cm3,在300~1500 m井段含有丰富的浅层气。文中从设备、工艺、浅层气钻井、顶部驱动钻井等几方面介绍了HALDA-1井在井控施工中的做法。

Well HALDA-1 is a directional well for developing the deep high pressured natural gas reservoirs in Bangladesh and it’s drilled for Cairn Energy PLC by the No. 5001 drilling crew of Zhongyuan Oilfield. The total depth is 4519.7m, and the highest drilling fluid density reaches 2.2g/cm3, meanwhile rich shallow gas is found in the interval from 300~1500m, thus well control is very important for the successful drilling. This paper introduces the conventional practices of western companies on well control, from such aspects as drilling equipment, operation procedure, drilling technology in the shallow gas reservoir, and top drive system.
