聚合物海水泥浆的研制

Development of Polymer Seawater Drilling Fluid

摘要:

以天然海水为分散介质，研制了一种新型、操作简便、无毒性、无污染的低成本高性能泥浆液。该泥浆液具有优良的护壁、防塌和流动性，能有效地抑制粘土水化膨胀与分散，起到孔壁稳定、提高海上勘探施工质量和效率的作用。它既可节约大量淡水资源，又可大幅降低我国岩土工程海上地质勘探之成本。

Abstract:

By the dispersion medium of seawater, a new type of low cost and easily operated high performance drilling fluid is developed without toxicity and contamination. This drilling fluid has fine hole wall protection, anti-sloughing and fluidity; can effectively inhibit hydration swelling and dispersion of clay, stabilize hole-wall and improve the quality and efficiency of maritime exploration with the effects of saving fresh water resources and maritime geological exploration cost.
