| Abstract: | A new organic silicate semi-permeable diaphragm agent of BTM-2 was introduced in this paper. Several properties of semi-permeable diaphragm drilling fluid were evaluated, which included cuttings recovery, contamination and temperature resistance and the efficiency of semi-permeable diaphragm. Results showed that this organic silicate semi-permeable diaphragm had an excellent semi-permeability, a strong inhibitive to hydration and swelling of the mud and shale, well dispersion, contamination tolerance and high temperature rheology. In-situ application showed that this drilling fluid had strong inhibitive and obvious anti-sloughing effect, the enlargement rate was small and normal hole was got. |
