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. 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.

钻井液添加剂一种钻井液添加剂，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。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。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。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。

阿尔法淀粉是将普通淀粉经预糊化处理，然后粉碎制成，现在被广泛应用于食品、水产养殖、医药、铸造和石油钻井等行业。
　　（三）阿尔法淀粉用途:
　　1、食品工业
　　阿尔法淀粉广泛应用于各种方便食品中，使用时可省去蒸煮操作，起到增稠。改进口感等作用。例如：用阿尔法淀粉配制的布丁粉，用冷牛奶搅匀即可食用；蛋糕粉中加入阿尔法淀粉，配蛋糕时加水易混成面团，包含水分和空气多，体积较大。
　　2、水产养殖业
　　阿尔法淀粉用于养殖业，其较主要的用途是配制在鳗鱼、甲鱼等饲料中。阿尔法淀粉作为水产饲料的粘结剂，其用量为20—25%。另外它可用来作观赏鱼饲料的粘合剂，使饲料颗粒光滑度增大，同时鱼也喜欢食用。
　　3、医药工业
　　在医药工业中预糊化淀粉主要作为药片粘合剂，它具有成型后强度大，服后易消化，易溶解及**的特点。
　　4、铸造生产工业
　　a、阿尔法淀粉可用作铸铁、铸钢用型砂的胶粘剂，冷水溶解*，胶粘力强，能提高型砂热湿拉强度，减缓石英砂受热潮胀，从而提高砂型的抗夹砂能力，防止铸件产生夹砂，结疤缺陷。
　　b、阿尔法淀粉能提高型砂韧性，减少因铸模不良而造成的型变，降低铸件废品率，减少经济损失。
　　c、阿尔法淀粉能提高型砂表面强度，提高抗风干能力及抗铁水充蚀能力，可防止冲砂、砂眼缺陷。
　　d、阿尔淀粉能降低型砂高温强度，改善溶性能。阿尔法淀粉使用方便，加入量少，一般为0.5—1%。
　　5、石油钻井业
　　a、石油钻井中使用阿尔法淀粉，可以稳定井壁，改善井眼条件，防塌，絮凝钻屑等作用，能显著地降低饱和盐水泥浆的失水，具有较好的抗钙和抗温能力，可用作饱和盐水泥浆的防滤失剂。
　　b、石油钻井应用阿尔法淀粉于油井钻泥中，可以增加蓄水性和稠度。

Product description:

Description: Drilling Starches manufactured by us are pre-gelatinized starch with potato, maize or tapioca as their base. They are used as fluid loss reducer in water based drilling muds for drilling and is also used extensively in mining operations. They are most preferred choice because of their excellent fluid loss reduction properties , high temperature resistance, viscosity and water holding/retaining property.

Our starch meets or exceeds API 13A specifications.

Applications / Advantages:
1) Our Drilling starch helps drills reach further and run freely.
2) They reduce fluid loss in water based drilling and provide temperature stability.
3) Our drilling starch maximizes solids removal and increase hydraulic efficiency.
4) They are easy to use and performs on wide variety of waters.
