致密砂岩油藏压裂投产水平井产能分析

Horizontal well productivity analysis with hydraulic fractures for close sand reservoir

  • 摘要: 针对致密砂岩油藏压裂投产水平井生产过程中,储层渗流场复杂的问题,在前人工作的基础上,利用井筒与油藏耦合模型,对模型中的裂缝流动压降进行修正,同时综合考虑储层启动压力梯度和应力敏感对产能的影响,推导出适合致密砂岩油藏压裂水平井的产能方程。研究结果表明,致密砂岩储层的启动压力梯度和应力敏感对水平井的产能影响显著,同时计算结果显示,推导的产能方程预测结果准确,能够指导水平井的开发。

     

    Abstract: Aiming at the complexity and multiple flow forms in fractured horizontal well for close sand reservoir,based on the previous work,by using wellbore-reservoir coupled mode,considering starting pressure gradient and stress sensitivity,the production flormula for horizontal well with hydraulic fractures in close sand reservoir has been established in this paper.The research results show that the effect of starting pressure gradient and stress sensitivity for horizontal well productivity is sensitive.Calculation results obtianed from examples show that relative error of productivity prediction calcultated through the model is small.The model can provide guidance for the horizontal well production.
