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

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 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.
