摘　　要：辽河油田W块为薄互层状普通稠油油藏,目前处于蒸汽吞吐末期,油井处于低产低效状态,继续吞吐潜力小。该块于2005年开展了面积井网多层火驱先导试验,取得了很好的效果。为了提升区块产量,决定进一步扩大火驱规模,针对区块构造特征,主体部位构造平缓设计采用面积井网火驱开发,构造较陡区域设计采用行列井网。采用数值模拟、油藏工程等方法进行行列井网火驱优化设计研究,设计最佳井网井距、注采参数,该研究对同类油藏火驱开发具有一定的借鉴作用。Block W in Liaohe oilfield is a deep multi-layers heavy oil reservoir which have entered the late development stage of cyclic steam stimulation.It is in urgent need to convert development scheme and improve recovery factor.Fire flooding of areal well pattern pilot test which carried in 2005 achieved good results.In 2013,the fire flooding scale enlarged in order to improve oil production.According to different stratigraphic dip in block,the areal well pattern applied in the gently area,line drive pattern applied in the cliffy area.Well pattern,well space,injection-production operation parameters are optimized by numerical simulation and reservoir engineering calculation.This research also provides certain technical reference for fire flooding in similar reservoirs.
