| description | Provided in the present application are a surface modifier for a drilling fluid and a preparation method for the surface modifier. The surface modifier for the drilling fluid of the present application comprises the following components in parts by mass: 100-130 parts of a polyether chain segment siloxane polymer; 60-80 parts of a block fluoroethylene copolymer; 60-70 parts of an acrylic higher ester polymer; 1-5 parts of mercaptan; 5-10 parts of nanoparticles; 10-15 parts of polyethylene glycol; 7-9 parts of trimethyl ammonium chloride; 10-25 parts of dimethyl ammonium chloride; and 400-500 parts of deionized water. The surface modifier for the drilling fluid can relieve the liquid-phase trap damage of a compact/shale reservoir, and can relieve oil film damage and emulsification damage possibly caused by an oil-based drilling fluid and a subsequent water-based working fluid, such that a test yield is improved.
