一、產(chǎn)品特性
在鉆井液中使用表面活性劑是泥漿技術(shù)的一個(gè)重要發(fā)展方向。由于某些表面活性劑具有改變粘土表面潤濕性，恰當(dāng)?shù)厥褂靡恍┨厥獗砻婊钚詣┨幚磴@井液后，可以提高體系的高溫穩(wěn)定性，減少處理劑用量；降低高溫失水，改善泥餅質(zhì)量和潤滑性；減少或防止鉆頭泥包，降低粘卡幾率；較大幅度地降低鉆井液內(nèi)摩擦力，對高密度泥漿具有突出的降PV效果。
DSA-1是以氟原子取代普通表面活性劑中碳?xì)渖系臍?，而形成碳氟親油基的表面活性劑。該產(chǎn)品具有優(yōu)良的高溫穩(wěn)定性和化學(xué)惰性以及“三高”、“二憎”特性，可大幅度降低泥漿表面張力、提高高溫穩(wěn)定性、特別是能提高鉆井液耐油氣污染能力，有利于油氣分離，還原真實(shí)鉆井液密度，使體系去污層仍有很好的流動(dòng)性，降低粘切力和降低高溫失水，在增強(qiáng)泥漿的潤滑性方面也非常突出，大大降低體系的維護(hù)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.
