Abstract

Based on the finite element method, numerical simulation on the state of present stress in Bozhong 25-1 oilfield which is the first low permeability oilfield carried out to be developed by CNOOC is studied. Combined with the geological characteristics, the impact of the stress on development is analyzed. It is showed that the stresses in the second and the third member of Shahezi Formation are pressure stresses and the direction of the maximum principle stress is mainly NEE-SWW. The stress is controlled by fault, structural relief and sedimentary microfacies on the plane. According to the state of the stress, the artificial fractures are vertical fracture in this area; the direction of the stress is seriously deflected near the fault, which causes the deflection of the extension direction of artificial fractures. Therefore, some adjustments should be made near the fault based on the actual distribution of stress, when the development well patterns are arrangement.
