摘要
随着水平井技术的成熟和发展,国内外对其的应用以由单水平井开发为主的开发模式逐步向以水平井井组整体开发为主的开发模式转化,相应的增产增注措施也被应用到了水平井领域。文中结合Бopисов水平井近井三维流场简化模型,从无限大地层内一酸化后的水平井出发,经过理论研究及数学推导,给出了水平井酸化后的产能公式,并结合算例评价了产能的影响因素及增注倍数与酸化半径的关系。
Along with the maturation and development of horizontal well technology, the application of it has been transformed that the pattern of developing horizontal well gradually transforms from central at single well to entirety development of well group. Accordingly the stimulations are applied in the area of horizontal well. In this paper, referred to simplified model of triaxial flow field near wellbore by Борисов, beginning at a acidized horizontal well in an infinite reservoir and accrossing theoretical research and mathematical derivation. The productivity formula of acidized horizontal well is finally obtained The effects of productivity and the relationship between stimulate multiplication factor and acidific radius are analyzed by case studies.
