泥浆材料A drilling-mud additive used to control fluid loss in water muds ranging from freshwater to saturated-salt to high-pH lime muds. Starches have thermal stability to about 250°F [121°C]. They are subject to bacterial attack unless protected by high salinity or bactericide. Drilling-grade natural starch has API/ISO specifications for quality. Starches are carbohydrates of a general formula (C6H10O5)n and are derived from corn, wheat, oats, rice, potatoes, yucca and similar plants and vegetables. They consist of about 27% linear polymer (amylose) and about 73% branched polymer (amylopectin). The two polymers are intertwined within starch granules.泥浆材料 Granules are insoluble in cold water, but soaking in hot water or under steam pressure ruptures their covering and the polymers hydrate into a colloidal suspension. This product is a pregelatinized starch and has been used in muds for many years. Amylose and amylopectin are nonionic polymers that do not interact with electrolytes. Derivatized starches, such as hydroxypropyl and carboxymethyl starches, are used in drill-in fluids, completion fluids and various brine systems as well as in drilling-mud systems. The use of starch typically causes a minimal increase in viscosity while effectively controlling fluid loss.泥浆材料
钻井液添加剂一种钻井液添加剂,泥浆材料用于控制淡水、饱和盐和高ph石灰泥浆中液体的流失淀粉热稳定到250°F(121°C)。除非受到高盐度或杀菌剂的保护,否则它们会受到细菌的攻击。泥浆材料钻孔级**淀粉具有API/ISO质量标准。淀粉是一种通用公式(C6H10O5)n的碳水化合物,来自玉米、小麦、燕麦、大米、土豆、丝兰和类似的植物和蔬菜。它们由27%的直链聚合物(直链直链淀粉)和73%的支链聚合物(支链淀粉)组成。这两种聚合物在淀粉颗粒中缠绕在一起。颗粒不溶于冷水,但浸泡在热水或蒸汽压力下会使其覆盖层破裂,聚合物水化形成胶体悬浮液。泥浆材料本产品是一种预糊化淀粉,已用于泥浆多年。直链淀粉和支链淀粉是非离子聚合物,不与电解质相互作用。衍生淀粉,如羟丙基和羧甲基淀粉,用于钻井液、完井液和各种盐水系统以及钻井泥浆系统。泥浆材料淀粉的使用通常导致粘度的较小增加,同时有效地控制了液体的损失。
