Abstract

The use of oil-mixed drilling fluid application may potentially affect the discovery of oil layer, as well as the results of chromatography or spectrum surface
logging. To study and quantify how the use of oil-mixed drilling fluid would affect the results of logging, high-resolution NMR surface logging while drilling technology was used to measure T2 spectrum and oil content with different levels of oil added into the drilling fluid. The results indicated that oil-mixed drilling fluid exhibited properties of oil in water, and could not blended with the oil layer. As a result, the T2 spectrum showed two independent peaks of oil. It is concluded that the oil layer can be identified accurately with the use of oil-mixed drilling fluid. In addition, by using the normalization method or external standard method, it was shown that the oil content of layer oil can be calculated in the drilling fluid. Field experiments were used to confirm the results of laboratory experiments.

Key words： oil-mixed drilling fluid; oil layer identification; oil content; NMR; quantified evaluation
