摘　　要：针对多套油水系统层状油藏储层非均质性强,含油带窄,注采井网完善难度较大,油井投产后普遍呈现含水上升快、产量递减迅速等问题,在层系细分适应性、合理井网优化和精细注水方式研究的基础上,通过转变油藏开发模式,有序细分层系调整,开展切割式注水、非主力层注水等精细调整,使目标区块采收率提高了3%左右。研究成果与调整实践对同类油藏合理有效开发具有借鉴意义。The stratified reservoir with multiple oil and water systems has strong heterogeneity,and narrow pay zone,making it difficult to improve injection and production pattern. After put into production,the oil wells commonly experience rapid rise of water cut and production decline. Based on research of adaptability of subdivision of strata,optimization of well pattern and refined water injection mode,combined specific adjustment policy,changes in reservoir production mode,orderly division of layers,line cutting flooding,and non-major layer injection resulted in an increase of the recovery factor by about 3%. These results and adjustment are of reference significance for efficient development of similar reservoirs.
