摘要:
基于低渗透气藏压裂水平井稳态产能模型,根据复位势理论,建立单条裂缝的平面势分布模型,运用势叠加原理和坐标变换方法,结合实际储层气体性质,建立裂缝与井筒成任意角度时,低渗透气藏压裂水平井稳态产能模型,在Visual Basic 6.0编程环境下,对模型进行求解,获得了压裂水平井产量.通过气藏开发实例计算分析表明,裂缝倾斜角度、水平段长度和裂缝半长是影响低渗透气藏产能的主要因素,而裂缝导流能力对其影响不大.在增产施工中,应尽量压开垂直裂缝,优化水平段长和裂缝长度,以获得更好的增产效果.
Abstract:
This paper presents a new mathematical model for studying the steady-state productivity of horizontal wells in low permeable gas reservoirs. Based on the complex potential theory, a plane potential distribution model of a single fracture was established. Following the superposition principle and the coordinate transformation method, the productivity model of a fractured horizontal well in low permeability gas reservoirs was established, which takes into account multiple fractures at any angle to the wellbore. The productivity dynamics of horizontal wells were then obtained with Visual Basic 6.0, and the reliability of this model was confirmed through a field case. Result shows that compared with fracture conductivity, the angles between fractures and wellbore, the length of the horizontal wellbore, and the half-length of fractures have primary influences on the production of fractured horizontal wells in low permeability gas reservoirs.
