Houwujiahu gas field of Lishu fault depression is in the early stage of exploration and development, because of the deeply buried target layer, the design depth of follow-up production well has deepening trend. Based on the analysis on geological conditions in this area and considering the technical difficulties of drilling, this paper makes the application analysis and evaluation of drilling speed increasing in wellbore structure design and the use of drill bit and dynamic drilling tools, and puts forward measures and suggestions for the drilling speed increasing suitable for this area.
