摘　　要：水平井开发是目前低渗透油田提高采收率,减缓递减的有效途径之一。前期已在长庆油田得到一定程度的应用。文章利用模糊判断法及层次分析法建立水平井举升方式优选模型,明确各影响因素的权重,进而模拟得出采油三厂水平井举升方式的优选结果,通过现场验证了结果的可行性。同时提出了低渗透油田水平井井筒配套技术,为后期低渗透油藏水平井开发提供借鉴。Horizontal well development is one of the effective ways to improve oil recovery and slow down decline in low permeability oilfields.In the early stage,it has been applied in Changqing oilfield to a certain extent.In this paper,the fuzzy judgment method and analytic hierarchy process are used to establish the optimization model of horizontal well lifting mode,to clarify the weight of each influencing factor,and then the optimization results of horizontal well lifting mode in the third oil production plant are obtained by simulation,and the feasibility of the results is verified by the field.At the same time,the matching technology of horizontal well bore in low permeability oilfield is put forward,which can provide reference for the development of horizontal well in the later stage of low permeability oil reservoir.
