Abstract:

Aimed at low pressure and high porous formation in the deep wells in Southern margin of Jungor Basin, Xinjiang, influence of various factors on differential sticking is analyzed. Two testing methods to evaluate differential sticking tendency are recommended for Xinjiang oil field. According to parts of laboratory testing results and the characteristic of deep well drilling fluids, the technological sticking tendency is established.

Key words: deep well, differential sticking, measuring instrument, analytical method, evaluation
