    摘要： The present invention relates to the field of petrochemical drilling and discloses a drilling fluid additive composition. The composition contains rheological modifier, emulsifier and tackifier. Among them, the rheological modifier is dimer acid-organic amine copolymer comprising structural units from dimer acid, structural units from alkylamine and structural units from arylamine; the tackifier is modified polysiloxane nano-particles, and the modifying group Z on the polysiloxane nano-particles is the emulsifier is one or more of the compounds represented by the following Formula (1). The present invention further provides a high temperature resistant clay-free whole-oil-based drilling fluid containing the foregoing composition. Through synergistic effect of the rheological modifier, the emulsifier and the tackifier in the composition, the present invention obtains a clay-free whole-oil-based drilling fluid with desirable suspending power and temperature resistance.
