QBY-1钻井液用强力包被抑制剂

QBY-1钻井液用强力包被抑制剂

产品详情

本产品是一种复合离子型共聚物乳液,该产品溶解速度非常快,水溶液呈中性,具备很强的抑制粘土和钻屑分散能力,具有良好的抗盐耐温性能,防塌效果较强,有利于油气层的保护。

一、产品特性

1、该产品是在常温下以乳液形式聚合而成的,具有足够长的链长度以形成相当强的包被、抑制作用。

2、产品溶解速度非常快,一般加入钻井液后两分钟内便可完全溶解,并且绝无漂浮结块的现象,利用率达100%,使钻井液得到及时处理。

3、因为该产品的分子量大、利用率高,所以其有效加量较小,一般加量12‰,即可达到满意的抑制效果。

4、引入一定比例的正电基团,增加了吸附基团对粘土的吸附力,并且可以释放抑制型离子,防塌效果非常好。

5、产品没毒、无荧光,适用于探井及对环保要求较高钻探环境。

QBY-1 Powerful Coating Inhibitor for Drilling Fluid

Product Details

This product is a composite ionic copolymer emulsion, which is very fast in dissolution rate, neutral in aqueous solution, strong in inhibiting the dispersing ability of clay and drill cuttings, and has good salt and heat resistance, and has excellent anti sloughing effect, which is favorable for the protection of oil and gas reservoirs.

Product Features

1. The product is polymerized in emulsion form at room temperature and has long enough chain length to form a very strong coating and inhibition.

2. The dissolution rate of the product is very fast. Generally, it can be completely dissolved within two minutes after adding drilling fluid, and there is no floating and caking phenomenon. The utilization rate reaches 100%, so that the drilling fluid can be treated in time.

3. Because of its large molecular weight and high utilization rate, the effective dosage of the product is small, generally 1-2 ‰ can achieve satisfactory inhibition effect.

4. The introduction of a certain proportion of positively charged groups increases the adsorption capacity of the adsorption groups on clay, and can release inhibitory ions, so the anti collapse effect is very good.

5. The product is non-toxic and non fluorescent, which is suitable for exploration wells and drilling environment with high requirements for environmental protection.
