Abstract

An oil-based drilling fluid and a preparation method therefor, and a method for preparing an anti-settling stabilizer. The method for preparing an anti- settling stabilizer comprises: using lithium bentonite and attapulgite as raw materials, and using an organic cationic surfactant and a non-ionic amine- terminated polyether compound as modifiers to modify the raw materials to obtain the anti-settling stabilizer. On the basis of the sum of the volumes of a base oil and a water phase being 100ml, the oil-based drilling fluid comprises: 80ml to 95ml of the base oil, 5ml to 20ml of the water phase, 3g to 6g of an emulsifier, 0.5g to 2g of a wetting agent, 0.25g to 2g of a viscosity regulator, 2g to 8g of a fluid loss agent, 2g to 4g of an alkalinity regulator, 0.2g to 1g of the anti-settling stabilizer and a weighting agent. The oil-based drilling fluid of the present application has better anti-settling stability and rheological properties under high temperature and high pressure conditions.
