摘　　要：研究了影响水平井产量的主要因素,重点研究了水平井长度与产量的关系。通过油藏内流动和水平井筒流动两者的耦合,建立了在层流状态下水平井长度与产量的关系式,研究结果说明在层流状态下水平井筒摩阻很小,水平井段各处产液强度相同。同时结合水平井产量公式,研究了影响水平井产量的其他因素,这些因素包括油层厚度、井眼半径、各向异性、控油半径、水平井在油层中纵向位置。This paper studied the controlling factors of horizontal well production, especially, the relationship between the length of horizontal well and the production. By coupling the reservoir flow with horizontal wellbore flow, the relationship between the length of the horizontal well and production in the laminar flow state was established. The results suggested that in laminar flow state, the friction of horizontal wellbore is very small, and produced fluid intensity is uniform throughout every horizontal section. Combined with production formula of horizontal wells, the relationship was used to study on other factors influencing oil output, including reservoir thickness, borehole radius, anisotropy, oil radius, and the vertical position of horizontal wells in the reservoir.
