Abstract: The study of reservoir interlayers is an indispensable content to reveal reservoir heterogeneity. The main formation of Chang 4+5 in Tianciwan South Oilfield of Jingbian Oil Production Plant has entered the development stage of high water cut, and the distribution of remaining oil is complex. In order to meet the needs of oilfield development and production, it is necessary to study the development status of interlayer in this formation. At present, the study of interlayers mainly relies on manual analysis of logging curves. Due to the variety of logging curves and the huge amount of data, the research process is time-consuming and low efficiency. This paper takes the Chang4+5 reservoir group of Tianci bay South Oil field of Jingbian Oil Production plant as the main research object, aiming at the existing problems of heavy workload and low accuracy, an automatic separation identification method is proposed. This method is based on logging data, and through digital filtering and gradient discrimination, it realizes rapid and accurate identification of interlayers.
