摘要：

根据陆东凹陷交南构造上侏罗统九佛堂组下段的地质条件、储层分布及地震反射特征,提出以组段为单元,通过速度谱资料处理,建立大层段沉积分布模式的储层预测;以砂组为单元,通过地震资料特殊处理的储层综合预测和以井间分形理论与地质统计学方法相结合的单层砂体预测等针对性预测方法,预测了储层及其分布范围,认为在构造高部位油藏受构造控制,而在倾没端明显受砂体控制,具有岩性-构造油藏的特点。交2、交12、交15井区块的北端及交2、交15井区块的西南端,砂体较厚、物性较好,属可能含油区,具有圈闭油气的条件。

Abstract:

Based on the geological condition,reservoir rock distribution and seismic reflection characteristics of the lower member of the Jiufutang Formation, Upper Jurassic in Jiaonan Structure, LudongDepression,it is proposed to take the lower member of the formation as the unit to make reservoir prediction of large section sedimentary model by velocity spectrum processing; to take sandstone set as the unit to make comprehensive reservoir prediction by seismic.data processing F to take interwell fractal analysis as theoritical basis and combine it with geostatistics to make individual sandbody predicting. The above memtioned prediction methods were adopted to predict hydrocarbon reservoirs and their distribution. It is constered that oil pools in the higher part of the structure are controlled by the strueture but that in the raking side possess the property of lithologic-structural pools. The sandbodies in the north side of Jiao-2, Jiao-12, Jiao-15 well-blocks and the southwest side of Jiao-2, Jiao-15 well-blocks are rather thick and have favourable physical features and hydrocarbon trapping condition.
