摘　　要：非均质性储层水淹不均匀 ,剩余油分布差异较大 ;一些水淹程度很弱或未被水淹的薄层或非均质性薄互层却有一定的石油储量和产能。胜利石油管理局测井公司针对这一特性开发研制了即有高纵向分辨率又具有一定探测深度的薄层测井系列仪器 ,包括径向变化的电阻率系列 (薄层三侧向、微球型聚焦、0 .2 5m和 0 .45m梯度、0 .5m电位、微电极等 )仪器 ;岩性孔隙度系列 (薄层声波、补偿密度、薄层伽马等 )仪器。列举了数口井的应用实例。在有些井的应用中发现了具有工业开采价值或潜在价值的薄油气层 ;提高了测井解释符合率 ;为沉积微相的识别 。Non-uniform waterflooded reservoir results from its inhomogeneity, so its residual oil distribution is quite different. Yet, several lightly waterflooded or non-waterflooded, or inhomogeneous cross thin layers often have an amount of reserves and producing capacity. From this point of view, Shengli Oilfield Logging Company has developed a new thin layer logging suite with high vertical resolution and better depth investigation, which includes a resistivity logging tool (e.g. thin bed laterologging-3, microspherically focused logging, 0.25 m and 0.45 m gradient array,0.5m electric potential, microelectrode logging, etc.) and litho-porosity logging tool such as thin bed acoustic logging, compensated density logging, thin bed gamma logging, etc.. The logging suite is run in near 60 wells, some of which indicate exploitable or potential oil and gas in the thin beds. With this suite, logging interpretation agreement rate is improved, thus, providing a good ground for identification of sedimentary facies and fine reservoir description.
