摘要： An inhibitive water-based polymer mud system and method for using the system in drilling and in stabilizing wellbores is disclosed for use in water sensitive formations as an alternative to oil-based muds or water-based muds comprising ferro-chrome lignosulfonates. The system comprises a fresh water or salt water base thinned or dispersed with a sulfonated acrylic copolymer having a hybrid/graft lignosulfonate multipolymer structure containing carboxylate and sulfonate functional groups with synthetic polymer side chains covalently linked to a base lignosulfonate material, having a molecular weight in the range of about 1,000 to about 15,000, and having a high anionic charge density. This system is effective and has stable rheology over a broad pH range, even at a near neutral pH of 8.0. The drilling fluids do not contain heavy metals and are Theologically tolerant to contaminants such as cement, anhydrite and sodium and temperatures as high as about 400°F.
摘要翻译：公开了一种用于钻井和稳定井筒的抑制性水基聚合物泥浆系统和方法，用于水敏性地层中，作为包含铁 - 铬木质素磺酸盐的油基泥浆或水基泥浆的替代物。该系统包含用磺化丙烯酸共聚物稀释或分散的淡水或盐水基质，其具有含羧酸盐和磺酸盐官能团的杂化/接枝木素磺酸盐多聚体结构，其中共聚合物侧链共价连接到碱性木质素磺酸盐材料上，分子量为约1,000至约15,000的范围，并且具有高的阴离子电荷密度。该系统是有效的，并且在宽pH范围内具有稳定的流变性，甚至在8.0的接近中性pH下。钻井液不含重金属，并且具有对水泥，无水石膏和钠等污染物的理论耐受性，温度高达约400°F。
