    Abstract:

    With the rapid growth of market demand for natural gas, how to successfully develop the rich CBM reservoir in Ningwu basin becomes an important subject in unconventional gas reservoir development. It is one of the key factors to scientifically determine a suitable drilling fluid density window by combining with the crustal stress state, the parameters of formation pore pressure and formation strength, as well as angle of deviation and azimuth angle in order to realize effective and safe coal-bed methane industrialization development in Ningwu basin. The finite element model of No. 9 coal seam in Ningwu basin is established by ANSYS software, the influence rule of hole enlargement ratio is analyzed in the conditions of different crustal stress directions and different well inclination, by which the optimized range of mud density is obtained to control coal seam collapse and reduce complex prescription, and the support for research on improvement of drilling efficiency and comprehensive benefit of CBM in NingWu basin is found.
