Abstract: Amine-based drilling fluid system DRABM is a new-type high-quality water-based drilling fluid developed independently by CNPC Drilling Engineering and Technological Research Institute, which is composed of SIAT, inhibitor filtrate loss reducer and lubricant. The test of shale cutting recovery ratio indicates that SIAT has a strong adsorption effect on the surface of shale and is able to inhibit hydration of shale effectively and improve the shale cutting recovery ratio obviously. Field application shows that amine-based drilling fluid system can inhibit hydration swelling and dispersion of most of surfactant shale and keep a good stability of well wall.
