摘要(Abstract)：
根据天然气对不同测井方法的影响,针对大庆外围地区地层的地质特点,利用中子孔隙度、密度曲线重叠法、P~(1/2)-正态概率法、空间模量差比法、视孔隙度比值法和四种孔隙度差值、比值法等气层解释方法,解释探井测井资料,气层解释成功率达80％左右,比1986年提高了约20％。 还对东部地区扶余、杨大城子油层进行了含气饱和度计算,与岩心分析资料对比,具有好的相关关系。
ABSTRACT
According 1o the effects of natural gas upon various methods of well-logging
and subsurface geological features at the periphery of Daqing oil-field, the
interpretation procedures (such as porosity-density curves overlapping, p -no rmal probability, space-module differential ratio, apparent porosity ratio and 4 types of porosity-differential values, correlative values etc) are used to interpret ale the log data of exploratory wells. Therefore, the successful interpretation of gas formation is about 80%, an increases by a factor of 20% compared to 1986. Comparisons between calculations of gas saturation and results of core analysis for Fuyu and Yangdachengzi formations are closely correlated.
