摘　　要：潜山高凝油油藏埋藏深,其裂缝分布规律需要综合应用岩心观察、测井识别与解释、地震属性与相干体分析、有限元分析、构造应力分析等方法进行研究。而且该类油藏温度高,储层润湿性为中—强亲水,对水、酸、碱不敏感,具有较好的注水可行性。沈625—229块边底水不活跃,天然能量不充足,需要注水进行开发。目前,该块全面注水已经初见成效,预示了良好的组合注水开发前景。Buried hill high pour-point oil reservoirs are deeply buried,fracture distribution needs to be studied by comprehensively using core observation,logging identification and interpretation,seismic attribute and coherent volume analysis,finite element analysis,and tectonic stress analysis.Moreover,such reservoirs have high temperature,medium-highly hydrophilic,not sensitive to water,acid and alkali,and have good feasibility of waterflooding.Shen625-229 Block has inactive edge-bottom water,insufficient natural energy,and needs to be developed by water injection.At present,full-scale water injection has received early effect and indicated the prospect of waterflooding.
