摘　　要：为改善洼16块注水开发稀油油藏的开发效果,提高油藏采收率,结合区块的地层条件及流体性质,开展了非均质油藏泡沫复合驱油室内研究及矿场试验,验证了该技术应用于普通稀油油藏区块的可行性。试验证明,该复合驱油体系具有较好的热稳定性及配伍性,室内驱油实验测定较常规水驱可提高驱油效率15%以上,且体系成本相对低廉,增产效果明显,为改善水驱开发效果提供了新技术支持。In order to improve development of Wa 16 block injected water developing thin oil reservoir and oil recovery,consid-ering the formation conditions of the block and fluid property,laboratory research and field test of heterogeneity reservoir have been carried out,which verified the feasibility of the technology to ordinary thin oil reservoir.The experiment proved that this combination oil flooding system has better thermal stability and compatibility.Laboratory displacement experiment mensuration shows it can improve oil displacement efficiency of more than 15% than conventional water flooding with low cost,which increase yield relatively and provided new technical support to improve the effect of water flooding development.
