摘　　要：冷 43块s32 油层属深层巨厚块状中低渗稠油油藏 ,隔层不发育。常规天然能量开发取得了较好的开发效果 ,但目前地层压力低 ,单井产量低 ,经济效益差。通过开发规律研究 ,提出今后提高采收率的方向。Reservoirs in s2 3 of block Leng43 are deep,extremely thick,massive,mid-low permeable,and bearing heavy oil.Restraining barrier had not developed.Conventional natural recovery had attained good result.But curren tformation pressure is low,single well production is low,and economic benefit is poor.So that the development law has been studied and the way of EOR has been pointed out for the future.
