Abstract
The present disclosure relates to the technical field of oil and gas drilling, and particularly relates to a modified silicon dioxide material of a fluorocarbon active agent type super-amphiphobic cutting-carrying agent suitable for a water-based drilling fluid, and a preparation method thereof. The preparation method of the modified silicon dioxide material comprises the following steps: subjecting silicon dioxide and a silane coupling agent represented by Formula (1) to a first contact reaction in a mixed solvent containing alcohol and water; subjecting the product of the first contact reaction, the compound represented by Formula (2) and the compound represented by Formula (3) to a second contact reaction; subjecting the product of the second contact reaction and the compound represented by Formula (4) to a third contact reaction. The modified silicon dioxide material can be used as a cutting-carrying agent in a water-based drilling fluid and produce an excellent cutting-carrying effect.
