本產(chǎn)品是一種復(fù)合離子型共聚物乳液,該產(chǎn)品溶解速度非常快,水溶液呈中性,具備很強的抑制粘土和鉆屑分散能力,具有良好的抗鹽耐溫性能,防塌效果較強,有利于油氣層的保護(hù)。
一、產(chǎn)品特性
1、該產(chǎn)品是在常溫下以乳液形式聚合而成的，具有足夠長的鏈長度以形成相當(dāng)強的包被、抑制作用。
2、產(chǎn)品溶解速度非?？?，一般加入鉆井液后兩分鐘內(nèi)便可完全溶解，并且絕無漂浮結(jié)塊的現(xiàn)象，利用率達(dá)100％，使鉆井液得到及時處理。
3、因為該產(chǎn)品的分子量大、利用率高，所以其有效加量較小,一般加量1～2‰,即可達(dá)到滿意的抑制效果。
4、引入一定比例的正電基團(tuán)，增加了吸附基團(tuán)對粘土的吸附力，并且可以釋放抑制型離子，防塌效果非常好。
5、產(chǎn)品沒毒、無熒光，適用于探井及對環(huán)保要求較高鉆探環(huán)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.
