摘要
针对水平井多级大规模压裂改造后各段测试产量效果评价的难题,通过研究水平井压裂改造后储层流体渗流机理,建立符合压裂特征的数学物理模型,形成了利用水平井分段测试求取的压力和产量数据评价改造效果的方法,实现了各段压裂规模的实施效果评价,为水平井多级压裂方案的优化提供了详实依据。
According to the problem of the production effect evaluation to horizontal wells after large-scale hydraulic fracturing,and by research on percolation mechanism of reservoir fluid after fracturing,mathematical physical model of fracturing characteristics is established,and method of using pressure and yield data acquired from segmented productivity test to horizontal well is formed,which realizes implemented effect evaluation of each section,and provides a basis in detail for the optimization of multi-stage fracture to horizontal well.
