摘　　要：针对超低渗透油田优质储量资源不足、直井开发产量低的特点,水平井开发技术得到推广应用。目前已开发的水平井主要存在井网形式不合理,造成水平井易见水、产量递减大等问题。本文以安塞油田某井区长6储层为例,利用油藏数值模拟的方法,确定了合理井网形式、储层改造参数以达到提高产量和采收率的目的。Aiming at the shortage of high quality reserves in ultra-low permeability oil field and the characteristics of low development output,horizontal well development technology is widely used..At present,the mainly horizontal well pattern is not reasonable,resulting in the problem of horizontal wells easy to see water,production decline and so on..Taking The Ansai Oilfield Chang 6 reservoir as an example,by using reservoir numerical simulation method,the paper determined the reasonable well pattern and reservoir transformation parameters in order to improve the yield and recovery.
