摘要

摘要: 当前环保形势日趋严峻，亟待广大钻井液从业者开发出一套可替代油基的水基钻井液体系，来解决页岩气水平钻进过程中存在的摩阻、井壁稳定以及井眼清洁等一系列难题。本次研究在硅酸钾钻井液强抑制、强封堵、易成膜的基础上，开发引入了一种具备协同封堵能力的强效水基润滑剂，并通过系列筛选和评价实验，构建了一套低摩阻硅酸钾钻井液体系。其润滑系数在0.08左右，抗磨砝码质量达到10 kg，具备媲美油基钻井液的润滑和抗磨性能；同时具有较低滤失量（FL_HTHP小于6 mL）；此外该体系还有较强的抑制和抗污染能力，流变易于控制，完全能满足页岩油气藏的开发需要。

Abstract: At present, with the increasingly severe environmental protection pressure, it is more and more urgent for drilling fluid practitioners to develop a set of water-based drilling fluid system that can replace oil-based to solve a series of problems such as friction, wellbore stability and borehole cleaning in the process of shale gas horizontal drilling. In this study, a potent water-based lubricant with synergistic plugging ability was developed and introduced on the basis of potassium silicate drilling fluid’s features such strong inhibition, strong plugging and easy film-forming.Finally, the low friction potassium silicate drilling fluid was constructed through a series of screening and evaluation experiments. Its lubrication coefficient is about 0.08, and the weight of anti-wear weight reaches 10 kg, which is comparable to oil-based lubrication and anti-wear performance; at the same time, it has a low filtration rate （FL_HTHP < 6 mL）; in addition, the system has strong inhibition and anti pollution ability, and its rheology is easy to control, which can fully meet the development needs of shale oil and gas reservoirs.
