摘要
针对海洋石油勘探深水钻井遇到的复杂问题 :井壁稳定性 ,钻井液用量大 ,地层破裂压力窗口窄 ,井眼清洗问题 ,低温下钻井液的流变性 ,浅层天然气与形成的气体水合物 ,对海洋深水钻井中使用的钻井液进行了综述。目的在于借鉴国外成功经验 ,为中国今后开展海洋石油勘探深水钻井方面的研究工作做一些技术信息的铺垫 ;并结合国外海洋深水钻井液研究现状 ,提出了对中国海洋深水钻井的钻井液研究的几点建议。
In this paper, complex problems encountered in deep water drilling during offshore petroleum exploration are summarized. Main topics include: wellbore stability, huge drilling fluid volume, narrow windows of formation breakdown pressure, hole cleaning, fluid rheology at low temperature, shallow natural gas hydrate formation. Drilling fluids for offshore deep water drilling are also introduced. This paper gave some successful foreign experience to researchers in this field. Advices on deep water drilling fluid research were proposed.
