Abstract

The research of fracture distribution direction is an important element for the development of fractured reservoirs.and it is directly related to well network deployment of reservoirs.The distribution of fracture direction is closely related to the stress field.By using of dipmeter and imaging logging data as well as the borehole stress analysis and borehole caving mechanism,the direction of ground stress of Ordovician carbonate rocks in Lunxi area is analyzed, and it is inferred that the distribution direction of structural fractures is NE-SW in the study area.It is man ifested that the direction of present-day ground stress and the effective fracture are the same direction or a slight angle oblique crossing.
