植物胶冲洗液在海洋勘察钻进护孔中的试验应用

Experimental Application of Vegetable Gum Drilling Fluid for Hole Protection in Ocean Exploration Drilling

摘要:

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Ga2+、Mg2+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。

Abstract:

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 Ca2 and Mg2  ions in the impurities, 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.
