| Abstract: |
| In order to study the influencing factors for profile control, the profile control measures were regarded as gray system. By the gray association analysis method, the association degree of different influencing factors with the profile control effect was analyzed, and the main influencing factors were determined. The results of profile control of 29 wells in recent three years of Dongxin Oilfield were analyzed with gray association method. Seven factors were selected ? The factors in order of decreasing influencing degree are water cut, well group connectivity, profile control times, profile control agent vol~ ume, permeability variation coefficient, crude oil viscosity and well group reserves. |
