海洋工程钻探由于受到环境条件的限制，常用海水配制泥浆。由于海水中含盐以及杂质中的Ga2＋、Mg2＋均对浆液的性能造成破坏，为此，通过对泥浆材料进行选择、配比，并经实践试验得出适合海上钻探环境的护壁泥浆，有效解决了海上钻探泥浆材料选择和具体配制问题。
海洋工程鑽探由于受到環境條件的限製，常用海水配製泥漿。由于海水中含鹽以及雜質中的Ga2＋、Mg2＋均對漿液的性能造成破壞，為此，通過對泥漿材料進行選擇、配比，併經實踐試驗得齣適閤海上鑽探環境的護壁泥漿，有效解決瞭海上鑽探泥漿材料選擇和具體配製問題。

Owing to the limitation of the surrounding environment on ocean engineering drilling, seawater is often used in drilling fluids preparation.The fluid properties are destroyed by salt in seawater as well as Ca2+and Mg2+ions in the impu-rities, through the selection of different mud materials and mixture ratios, the drilling fluid suitable for offshore drilling were obtained with the practice tests, the material selection and specific preparation for offshore drilling mud were effectively solved.
