有機高分子降濾失劑的分子尺寸在膠體顆粒范圍內，加入這些外處理劑后，它們一方面使分子的長鏈楔入濾餅的間隙中，另一方面長鏈子卷曲成球狀，堵塞濾餅微孔隙，使濾餅薄而細致，從而降低濾失量。
鉆井液添加劑一種鉆井液添加劑，用于控制淡水、飽和鹽和高ph石灰泥漿中液體的流失淀粉熱穩定到250°F(121°C)。

泥漿材料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.泥漿材料 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.

鉆井液添加劑一種鉆井液添加劑，泥漿材料用于控制淡水、飽和鹽和高ph石灰泥漿中液體的流失淀粉熱穩定到250°F(121°C)。除非受到高鹽度或殺菌劑的保護，否則它們會受到細菌的攻擊。鉆孔級天然淀粉具有API/ISO質量標準。淀粉是一種通用公式(C6H10O5)n的碳水化合物，泥漿材料來自玉米、小麥、燕麥、大米、土豆、絲蘭和類似的植物和蔬菜。它們由27%的直鏈聚合物(直鏈直鏈淀粉)和73%的支鏈聚合物(支鏈淀粉)組成。這兩種聚合物在淀粉顆粒中纏繞在一起。顆粒不溶于冷水，但浸泡在熱水或蒸汽壓力下會使其覆蓋層破裂，聚合物水化形成膠體懸浮液。本產品是一種預糊化淀粉，已用于泥漿多年。直鏈淀粉和支鏈淀粉是非離子聚合物，不與電解質相互作用。衍生淀粉，如羥丙基和羧甲基淀粉，用于鉆井液、完井液和各種鹽水系統以及鉆井泥漿系統。淀粉的使用通常導致粘度的較小增加，同時有效地控制了液體的損失。

吸附在粘土表面形成吸附層，以阻止粘土顆粒絮凝變大。

濾失量與鉆井液濾液粘度的0.5次方成反比。有機降濾失劑加入鉆井液后提高了濾液粘度，使濾失量降低。
為了形成滲透率低的泥餅，要求鉆井液中粘土顆粒粒徑有合適的大小分布，同時要求有較多的細顆粒。降濾失劑的護膠作用在于：

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.
