摘　　要：Jxx断块是华北油田较好的整装砂岩油藏,采出程度达51.8%,水驱效果明显。为完善开发方案,挖掘剩余油,进行了水平井的部署。通过对水平井井眼轨迹及储层含油性的分析,搞清了水平井井眼轨迹与地层的接触关系,认为储层本身的含油性好坏是影响注采效果的主要因素,而储层均质性好坏也是制约注采效果的重要因素,对水平井开发效果评价尤其是效果跟踪评价发挥了重要作用,拓展了测井资料在地质领域的应用。Fault Jxx is one of the best sand reservoirs in Huabei oilfield,the recovery of the reservoir is up to 51.8% with goodflooding effect. Horizontal well was applied to explore remaining oil. The contact between wellbore trajectory and target formationis observed by the analysis of wellbore trajectory and oil bearing properties of the reservoir. It indicates that the oil bearing propertiesof the reservoir contributes much on the effect of injection and recovery,moreover,the homogeneities of the reservoir also playsimportant role in this procedure,which are crucial in the evaluation on the development of the horizontal well,especially trackingevaluation,and will be widely used for logging data in geology.
