供应泥浆材料厂家

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.
5) Drilling Starch is widely used in mining operations.

滤失量与钻井液滤液粘度的0.5次方成反比。**降滤失剂加入钻井液后提高了滤液粘度，使滤失量降低。

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。

泥浆材料降滤失剂在钻井液工作中的四大作用：
　　一.护胶作用
　　为了形成渗透率低的泥饼，要求钻井液中粘土颗粒粒径有合适的大小分布，同时要求有较多的细颗粒。降滤失剂的护胶作用在于：
　　1.泥浆材料吸附在粘土表面形成吸附层，以阻止粘土颗粒絮凝变大。
　　2.泥浆材料能把泥浆循环系统搅拌下所拆散的细颗粒通过吸附稳定下来，不在粘结成大颗粒。这样增加了细颗粒的比例，有利于形成细致泥饼。
　　二.提高滤液粘度可以降低滤失量
　　泥浆材料滤失量与钻井液滤液粘度的0.5次方成反比。**降滤失剂加入钻井液后提高了滤液粘度，使滤失量降低。
　　三.增加钻井液中搬土颗粒的水化程度
　　泥浆材料这样可以降低滤失量。降滤失剂吸附在钻液中的搬土颗粒上，使其水化程度增加颗粒的水化膜增厚，形成的滤饼在高压下易变形，滤饼的渗透率降低。
　　四.泥浆材料降滤失滤剂分子本身的堵孔作用
　　泥浆材料**高分子降滤失剂的分子尺寸在胶体颗粒范围内，加入这些外处理剂后，它们一方面使分子的长链楔入滤饼的间隙中，另一方面长链子卷曲成球状，堵塞滤饼微孔隙，使滤饼薄而细致，从而降低滤失量。
