- Abstract
The fracture system of fractured reservoir is complex, which largely affects the underground oil-gas seepage channel and the reservoir shows unconventional development characteristics. It has a great influence on the ultimate production of oil wells. In this paper, we take fractured reservoir as the research object, on the basis of hydraulic fracture morphology after it meets the natural fractures. Also we respectively study the influences of single and multiple symmetrically natural fractures to well productivity after fracturing, using the ECLIPSE reservoir simulation software. Then, we compare it with the case without influence of natural fractures and analyze the result. The result shows that natural fractures connected with hydraulic fracture make the daily production and cumulative production of wells decline which are the non-central on the diagonal of the well group. Moreover, natural fractures with certain length and density increase the daily production and cumulative production of wells which are central on the diagonal of the well group.
