The utility model discloses a distorting hole sheet type oil-gas-water three-phase flow static mixer which comprises three distorting sheets and a mixing tube bundle section, wherein the three distorting sheets are formed by distorting surfaces vertical to a longest side of a flat plate as starting surfaces along the longest side for 180 DEG, two connecting surfaces connected between two adjacent distorting sheets are installed in a vertical crossing manner and are fixed through welding, and then embedded in the mixing tube bundle section after being connected, and fixed with the inner wall of the mixing tube bundle section through welding to form a static mixer, and the static mixer is connected between main tube bundle sections. Three-phase flow through holes can be also formed in a plane formed by width and length of the flat plate along two sides of a perpendicular bisector of the width, wherein the length is more than the width and the width is more than the height. According to the distorting hole sheet type oil-gas-water three-phase flow static mixer, a plurality of distorting sheets are arranged in the vertical crossing manner, thus rapid and efficient mixing of oil-gas-water three phase flows is achieved, and the pressure loss is reduced; a turbulence effect of a multi-phase fluid can be increased due to the multi-phase flow mixing holes in the distorting sheets, so that a continuous fluid phase is crushed into a dispersed phase, and multiple phase flows are rapidly mixed.
