摘要: 用热流场模拟射孔完井渗流场,建立了射孔完井热流和裸眼完井热流有限元三维模型。用同一种导热率材料来模拟井筒和孔眼,该材料导热率相对于地层模型导热率为无限大时,能模拟整个射孔完井渗流场。根据该模型,研究了射孔深度、有无钻井污染和压实带情况下,孔眼内流体流速、压实带外边界渗流速度、渗流压力场、全井产量及产能比等,为研究射孔完井优化设计、产能预测等提供了新方法,对射孔完井评价也具有实际的指导意义。

Abstract: 3D finite element model for thermal fluids of perforated completion and open hole completion is developed by using thermal fluid field for simulating percolation field in perforated completion. The material with same thermal conductivity is adopted to make well-bore and perforated hole simulation. When the thermal conductivity of material is infinite to that of formation model, the simulation of whole percolation fields of perforated completion can be performed. Based on the models, this paper also studies the flowing velocity within perforated hole, boundary flowing velocity beyond compacted zone, flowing pressure field, full hole producing rate and productivity ratio under some perforated depth, with or without driling fluid pollution and compacted zone. The novel method could be helpful to opti-mized design of perforated completion and prediction of productivity. Also, it is of more practical significance for evaluation of perforated completion.
