| description | The invention relates to a preparation method of organic bentonite for drilling fluid. The method comprises the steps of: dissolving a sodium bentonite dry material in water, and stirring to form a suspension system a; mixing and dissolving an organic modifier in xylene, and stirring and dissolving to form a system b; dissolving an assistant A in deionized water, stirring, dissolving and heating, adding an assistant B, and reacting to form a uniform system c; adding the system b into the suspension system a while stirring, and reacting to form a uniform system d; and adding the system c into the suspension system d while stirring, and cooling, washing, filtering, drying, crushing and sieving a reaction product to obtain the organic bentonite for drilling fluid. The organic bentonite prepared by the method disclosed by the invention has good rheological property and compatibility in a system.
本发明涉及一种钻井液用有机膨润土的制备方法。钠基膨润土干料溶于水中，搅拌，形成悬浮体系a；将有机改性剂混溶于二甲苯中，搅拌溶解形成体系b；将助剂A溶于去离子水中，搅拌溶解加热，加入助剂B，反应形成均一体系c；搅拌下，将体系b加入到悬浮体系 |
