摘　　要：针对华北油田近年来预探发现的隐蔽油藏构造背景复杂、储层类型多样、电性差异大、以低孔低渗型储层为主的实际特点,在油藏评价研究中采用了叠前时间偏移处理、储层预测与描述、复杂油层的识别及改造等关键技术,不仅有效地提高了油藏评价的效益,也为提高储量动用程度和新建产能提供了有效途径。As the reservoirs discovered in recent years in Huabei Oil Field are those subtle reservoirs of high complexity in structure and formation style,high resistivity variation,and low porosity and permeability,new techniques such as pre-stack time domain migration of seismic data,reservoir prediction and delineation,abnormal pay zone identification and treatment are introduced,thus bringing high economical benefits,high ratio of reserve productivity,and showing themselves effective ways for production promotion.
