摘要
“优快钻完井”是具有中国海油特色的技术体系和管理模式,在海洋石油工业史上留下了浓墨重彩的一笔,取得了瞩目成就。钻完井液在优快钻井中一直扮演重要的角色。一次优快产生泥浆固相含量高效控制技术,二次优快产生海水膨润土浆深钻工艺和强抑制钻井液技术体系,而“新优快”试点项目,以“浅层疏松、大斜度、大位移”为主要井型,最大水垂比4.02,磨阻扭矩高,井眼清洁困难,开发研制一种不同于以往水基钻井液的新型流型调节剂变得尤为关键,流型调节剂是影响钻井液悬浮、携带及稳定井壁能力的重要因素,通过新型流型调节剂可以钻井液携带能力提高井筒清洁度,从而减少复杂情况的发生,保证钻井过程顺利。
"Excellent fast dilling and completion of wells"is a technical system and management mode with CNOOC characteristics,which has left a strong mark in the history of offshore oil industry and has made remarkable achievements.Drilling and completion fluid has always played an important role in the fast drilling.Efficient control technology of primary superior and fast generated mud solid phase content,deep drlling process of seawater bentonite slurry and strong inhibitory drilling fluid,And the"New Excellent Fast"pilot project,With"shallow loose type,large slope,large displacement"as the main well type,maximum water vertical ratio of 3.17,high grinding torque,difficulties in performing the borehole cleaning,developing a new rheolobic modifiers different from previous water-based drilling fluid is particularly critical,flow regulator is an important factor affecting the suspension,carry and stabilize the wall of drilling fluid,the new rheolobic modifiers can improve drilling fluid carrying capacity to improve shaft cleanliness,thus reducing the occurrence of complex situations,ensure the smooth drlling process.
