Abstract:

The wireline drilling technology was widely used in the coal region of Quang Ninh. However, the geological characteristics of this area are very complex, the operating by wireline drilling has encountered many problems. The swelling, collapsing of borehole vary in an extensive limit and depend on many factors: mineral composition; dispersion degree; chemical exchange components and environmental catalytic factors such as chemical composition of drilling fluid, temperature and hydrostatic pressure, etc... The instability of borehole is caused by using drilling fluid with inappropriate parameters and rheological properties. In this paper, the authors present research results in order to improve wireline drilling technology in the coal region of Quang Ninh.
