安塞油田提高水平井单井产能技术探索

Discussion on single well production improvement of horizontal wells in Ansai oilfield

  • 摘要: 水平井开采技术是提高低渗透、超低渗透油藏单井产能的主要手段之一,在安塞特低渗油田得到了推广应用。近几年安塞低渗透油田在开采过程中出现了产能下降、含水上升等问题,为此,在分析影响因素的基础上,开展了水平井机械堵水、水力喷射压裂、酸化等提高单井产能工艺技术探索与应用,取得了良好的增产效果。

     

    Abstract: Horizontal wells developing technology is one of the primary methods to improve the single well production of lowpermeability,ultra low-penetration reservoir,which has been used in Ansai extra-low permeability field recent years.However,problems such as production decline and water-saturation arised in the developing process.To solve this problem,based on influential factors analysis,technologies that improve single production has been carried out,which includes mechanical water plugging towards horizontal wells,hydraulic fracturing and acidification measures.Application effects show long-term stable production of horizontal wells has been realized.
