【摘要】 根据钻井岩屑、钻井取芯、薄片镜下观察,再结合岩石类型、测井分析与地震相解释等地质资料的综合分析,川东南地区嘉陵江组可划分为开阔台地亚相、局限台地亚相、蒸发台地亚相等。再依据区域地质资料及不同的地震反射特征,划分出了连续席状地震相、叠瓦状前积地震相、迭瓦状前积伴随波状、短轴状地震相,以及低频强振幅特点地震相等。最后,将沉积相分析和地震相分析相结合,对有利目标区域进行综合评价以及最终的确定。更多还原

【Abstract】 According to drilling cuttings, drilling core and thin microscope, combined with a comprehensive analysis of rock types, log analysis and seismic facies interpretation of geological data, the southeast region of Sichuan Jialingjiang formation can be divided into open platform subfacies, restricted platform subfacies, evaporate platform subfacies. And then based on regional geological data and different seismic reflection characteristics, there are divisions of continuous sheet facies, former plot seismic facies of imbricated product, former plot seismic facies of imbricated product with wavy and minor axis, and the low frequency high amplitude characteristic seismic facies. Combination of sedimentary facies analysis and seismic facies analysis can provide the basis for comprehensie valuation and determination of favorable target areas.更多还原
