摘　　要：在水平井开发可行性论证及优化设计中,水平井产能预测是决策方案的重要依据。与中高渗油田相比,低渗透油藏渗流规律不同于中高渗油藏,必须考虑启动压力梯度对产能的作用。为了充分发挥水平井开采低渗透油藏技术的经济效益,提高水平井产能,文章研究了影响其产能的主要因素,为水平井高效开发低渗透油藏提供借鉴。The horizontal well productivity prediction is an important basis for decision - making strategy in the fea- sibility demonstration of horizontal well development and its optimizing designing. Comparing with middle and high permeability oiffields, seepage regular of low permeability reservoir is different ; effects of start - up pressure gradi- ent on productivity should be considered. In order to fully explore the economic efficiency of low permeability reser- voir developed by horizontal well technology and booster horizontal well productivity, the factors effecting the pro- ductivity have been further studied, which gives the reference for the efficient development of low permeability res- ervoir by horizontal well.
