一、产品特性
在钻井液中使用表面活性剂是泥浆技术的一个重要发展方向。由于某些表面活性剂具有改变粘土表面润湿性,恰当地使用一些特殊表面活性剂处理钻井液后,可以提高体系的高温稳定性,减少处理剂用量;降低高温失水,改善泥饼质量和润滑性;减少或防止钻头泥包,降低粘卡几率;较大幅度地降低钻井液内摩擦力,对高密度泥浆具有突出的降PV效果。
DSA-1是以氟原子取代普通表面活性剂中碳氢上的氢,而形成碳氟亲油基的表面活性剂。该产品具有优良的高温稳定性和化学惰性以及“三高”、“二憎”特性,可大幅度降低泥浆表面张力、提高高温稳定性、特别是能提高钻井液耐油气污染能力,有利于油气分离,还原真实钻井液密度,使体系去污层仍有很好的流动性,降低粘切力和降低高温失水,在增强泥浆的润滑性方面也非常突出,大大降低体系的维护成本。

DSA-1 Surfactant for Drilling Fluid
Product Details
Product Features
Using surfactant in drilling fluid is an important development direction of mud technology. Because some surfactants can change the wettability of clay surface, properly using some special surfactants to treat drilling fluid can improve the high temperature stability of the system and reduce the dosage of treatment agent; Reduce high temperature water loss, improve the quality and lubricity of mud cake; Reduce or prevent bit mud bag and reduce sticking probability; The friction force in drilling fluid is greatly reduced, and the PV reduction effect is prominent for high density mud.
DSA-1 is a kind of surfactant which uses fluorine atom to replace hydrogen on hydrocarbon in common surfactant to form fluorocarbon lipophilic group. The product has excellent high temperature stability, chemical inertness and "three high" and "two hydrophobic" characteristics. It can greatly reduce the mud surface tension, improve the high temperature stability, especially improve the oil and gas pollution resistance of drilling fluid, which is conducive to oil and gas separation, restore the real drilling fluid density, make the decontamination layer of the system still have good fluidity, reduce the viscosity and reduce high temperature water loss, It is also very prominent in enhancing the lubricity of mud, greatly reducing the maintenance cost of the system.
