    • A method for modeling flow properties over a series of time increments of a reservoir in an earth formation having a plurality of fractures is disclosed. The method includes: building a three-dimensional stress field representing stresses in the reservoir; building a three-dimensional discrete fracture network (NFM) having fracture flow properties using information obtained from a tool or changes to the stress field; running a flow simulation of the reservoir for a time increment using the NFM to model the flow properties of the reservoir for that time increment; computing a latest change in the three-dimensional stress field from the flow simulation; and incrementing the time increment and iterating the building the NFM using the latest change in the stress field, the running of the flow simulation using the latest NFM, and the computing a latest change in the stress field from the latest running of the flow simulation.
    • 公开了一种用于在具有多个裂缝的地层中的储层的一系列时间增量上对流动性进行建模的方法。 该方法包括:建立代表油藏中应力的三维应力场; 使用从工具获得的信息或对应力场的变化构建具有断裂流动性的三维离散裂缝网络(NFM); 使用NFM对储层的流动模拟进行时间增量,以模拟该时间增量的储层的流动性质; 从流动模拟计算三维应力场的最新变化; 并增加时间增量,并使用应力场的最新变化,运行使用最新NFM的流量模拟,以及从流式仿真的最新运行计算应力场的最新变化来迭代构建NFM。
