摘　　要：水平井立体井网是为高效开发巨厚潜山油藏而设计的一种新型井网,其宏观渗流规律和具体开发方式需要明确。采用数值模拟方法,研究对比了不同开发方式下的渗流特征和开发效果。结果表明,逐层上返底部注水和逐层下探顶部注气相结合的开发方式效果最佳,明显优于底部注水、顶部注水、顶部注气和逐层上返。水平井立体井网逐层上返底部注水和逐层下探顶部注气相结合的开发方式可以高效开发巨厚潜山类油藏,同时为所有巨厚油藏的开发提供了参考。Stereo horizontal well pattern,whose macro flow laws and concrete developing method need to be definite,is a newwell pattern designed for developing giant thick buried hill reservoirs efficiently.Based on numerical method,the flow characteristics and development effectwith different developing methods are studied.The results show that the developing method combining zone by zone up-going bottomwater injection and zone by zone down-going top gas injection is the best.It's development effectis better than thatof bottomwaterinjection,topwaterinjection, top gas injection and zone by zone up-going.The stereo horizontal well pattern with the developing method can develop the giant thick buried hill reservoirs efficiently.It can also provide a reference for giant thick reservoirs development.
