压裂水平井产能预测方法研究进展

水平井压裂技术在低渗透及非常规储层中得到了广泛应用,压裂后水平井的产能预测关系到油田开发方案的制定,因此,国内外学者对压后渗流模型的建立和求解方法做出了不懈的努力。本文详细回顾了国内外学者所建压裂水平井产能预测模型及求解方法,指出了不同模型和求解方法的优缺点,并展望了压裂水平井产能模型的发展方向。

Research progress of productivity prediction methods for fractured horizontal well

Horizontal well and fracturing technology are widely used in low permeability and unconventional reservoirs.The productivity prediction of horizontal well after fracturing is related to the formulation of oilfield development plan.Therefore,scholars at home and abroad have made unremitting efforts to establish and solve the percolation model after fracturing.In this paper,the productivity prediction models and solution methods of fractured horizontal well established by domestic and foreign scholars are reviewed in detail,the advantages and disadvantages of different models and solutions are pointed out,and the development direction of productivity model of fractured horizontal well is prospected.
