摘　　要：鄚东地区钻井过程中经常发生垮塌、卡钻、井漏等复杂事故。该地区深井钻井采用了抑制性及封堵性较强的铵基沥青树脂高密度钻井液体系,并根据地层特点,对不同井段制定了相应的钻井液维护处理措施。结果表明,该钻井液体系抑制性好,抗温、抗污染能力强,性能稳定,成功地控制了复杂事故的发生,满足了该地区深层钻井的要求。Mao east area frequently takes place sloughing hole, pipe-stuck, lost circulation in drilling operation. Deep drilling in this area not only adopts heavy and weight system of amino asphalt with strong inhibiting and plugging but also detemines corrospondently technical measures of drilling fluid in processing and maintance according to different depth and different formation. This drilling fluid technique successfully solves the drilling problems in this area.
