Abstract
The organic salt drilling lfuid of Weigh series has advantages of strong inhibition, high temperature resistance and low friction, and it has been the main drilling technology in complex situations at home and abroad. In this paper, the water activity of Weigh organic salt drilling lfuid, the thickness of adsorption-diffusion double electrode layers of clay colloidal particles after the Weigh organic salt drilling lfuid effect, and the layer space of montmorillonite crystal were measured in laboratory. Then, the inhibition mechanisms of Weigh organic salt drilling lfuid were discussed from three aspects, i.e., activity, double electrode layer and ion exchanging lattice embedment. It has been successfully applied in two extended reach wells in the Beibu Gulf, western South China Sea. It provides the technical support for the development of similar oil ifelds in western South China Sea.关键词
