Production Contribution Analyse on Outer Region of Stimulated Reservoir Volume in Condensate Shale Gas Well:Taking Typical Condensate Shale Gas Well in Eagle Ford as an Example
Taking typical condensate shale gas well in Eagle Ford as an example,a trilinear flow mathematical model is established,and the shale property parameters and hydraulic fracture parameters are derived based on the history match of production data.Thus the production contribution of outer region of stimulated reservoir volume was analyzed.Results show that the outer region can supply oil and gas to well and the production contribution of the outer region increases with shale matrix permeability.In the first five years production,the contribution area of outer region is within 40 m and the most contribution is with 20 m.In the thirty years production,the contribution area of outer region is within 60 m.
