【摘要】 应用层序地层学理论,对川西北部地区侏罗系的层序界面、体系域及各层序特征进行了分析,将川西北部地区侏罗系划分出13个层序界面和13个三级层序,认为各层序主要由退积体系域和进积体系域组成。结合层序地层学及储层研究,认为进积体系域有利于三角洲储层的发育。更多还原

【Abstract】 By applying the sequence stratigraphy theory, the sequence interface a nd the system as well as the characteristic of all kinds of layers are analyzed. Jurassic system in SICHUAN northwest area is divided into 13 sequence interface s and 13 triple sequences, the sequences are deemed to be composed by retrogradi ng sequence and progradational sequence. By studying sequence stratigraphy theor y and the reservoirs, progradational sequence is deemed to be advantage to devel op the delta reservoirs.更多还原
