摘　　要：北大港油田是一个以油层为主,纵向上油气层交互分布的油(气)田,部分天然气随油一同采出。在重油轻气的情况下,往往忽略了气层解释方法的研究,使气层解释符合率较低。针对气层解释符合率的现状,开展了测井系列调查。北大港油田从1964年到目前应用了3种不同测井系列,主要以横向和声感应测井系列为主,数控测井系列所占比例很小,使目前较新的测井解释技术和方法的应用,受到了一定限制。尽管如此,文中根据北大港油田的实际情况和浅层气测井响应特征,充分利用老资料,研究出了不同测井系列的浅层气测井识别方法。Beidagang oilfield is an oil/gas field mainly consisting of oil layers where the oil layers and the gas layers are inter-bedded vertically. Some gas is exploited along with oil together. Under the situation of emphasizing oil much more than gas in the past, the study on the interpretation method of gas layers was usually omitted, which made the coincidence rate of gas layer interpretation low. Aiming at the current status, the logging series used in Beidagang oilfield is investigated. Since 1964, 3 different logging series have been applied, but the lateral logging series and the acoustic induction logging series prevail. The digital control logging series accounts for a little proportion only. So, the application of new techniques and methods for logging interpretation is limited. However, according to the concrete situation of Beidagang oilfield and the logging response features of the shallow gas layers, and making good use of the old data, the recognition method of shallow gas layers by various logging series is developed.
