摘　　要：烷基糖苷在钻井液中成膜润滑效果好,但加量大,吸附能力差,抗温性不足。在烷基糖苷润滑性能优势基础上,通过分子理论设计,引入磺酸基、胺基、长链烷基等功能基团,制备得到高润滑、低加量、强吸附、抗高温的磺化胺基烷基糖苷(LAPG)产品。性能评价结果表明,产品抗温达200℃;加量为1.0%时可使5.0%膨润土浆的润滑系数由0.405降至0.073,润滑系数降低率达81.98%;对钻井液表观粘度基本无影响,具有显著降滤失作用;无生物毒性,绿色环保。LAPG产品可有效解决高温深井超深井、长水平段水平井、大位移井的高摩阻控制难题,避免托压卡钻等井下情况发生,满足现场绿色、安全、高效钻进,具有较好推广应用前景。Alkyl polyglucoside has good film-forming and lubrication effect in drilling fluid,but its dosage is large,adsorption capacity is poor and temperature resistance is insufficient.Based on the advantages of alkyl polyglucoside in lubrication performance,sulfonated amino alkyl polyglucoside(LAPG)products with high lubrication,low dosage,strong adsorption and high temperature resistance were prepared by introducing functional groups such as sulfonic group,amino group and long chain alkyl group through molecular theory design.The results of performance evaluation show that the temperature resistance of the product reaches 200℃;when the dosage is 1.0%,the lubrication coefficient of 5.0%bentonite slurry can be reduced from 0.405 to 0.073,and the reduction rate of lubrication coefficient can reach 81.98%;it has no effect on the apparent viscosity of drilling fluid,and has significant filtration reduction effect;it has no biological toxicity and is environmentally friendly.LAPG products can effectively solve the high friction control problems of high temperature deep wells and ultra deep wells,long horizontal section horizontal wells and extended reach wells,avoid downhole complications such as directional drag and sticking,meet the requirements of green,safe and efficient drilling on site,and have good application prospects.
