Numerical simulation study on law of steam flooding in oil reservoir with directional fractures

In this paper, the law of steam flooding in reservoir with different directional fractures is studied by two measures through numerical simulation. On the basis of geological research on steam flooding in a test area of Daqing Chaoyanggou Oilfield, the ideal geological model is established using Petrel software, and then numerical simulation is carried on applying the STARS simulation module of CMG software. The major study is about the law of steam flooding, under the two measures of well off and increasing liquid production, in fractural low-permeability reservoir with different fracture directions. The results show that the best development effect is available when the angle between the well array and fracture is 0° under the measure of well off and when the angle between the well array and fracture is 45° under the measure of increasing liquid production. This study results have some significance to the actual production of the oilfield.
