The invention provides a myriameter deep oil-gas wall-fixing type water-based drilling fluid as well as a preparation method and application thereof, and belongs to the technical field of drilling fluids. The myriameter deep oil gas wall-fixing type water-based drilling fluid is prepared from the following raw materials in parts by weight: 100 parts of water, 1-5 parts of a modified clay shear strength improving agent, 2-4 parts of a hydrophobic association polymer flow pattern regulator, 3-8 parts of a blocking agent, 2-5 parts of a hyperbranched polymer filtrate reducer and 1-3 parts of a cementation blocking type wall-fixing agent. The invention also provides a preparation method of the drilling fluid. The components such as the flow pattern regulator, the plugging agent, the filtrate reducer and the wall-fixing agent are mutually matched and synergistic, so that the drilling fluid can keep good rheological, filtration, plugging and inhibition performances for a long time under the conditions of 240 DEG C and saturated salt, has a strong wall-fixing effect, can effectively maintain the stability of the well wall of an oil-gas well in the depth of 10,000 meters, and has a wide application prospect. And well collapse, well leakage, blowout and other complex well drilling are prevented, and the drilling tool can be used for drilling oil and gas wells with the depth of ten thousand meters.
