准噶尔盆地红87井区克上组沉积相特征

本文在对准噶尔盆地红山嘴油田红87井区各井所取的三叠系克上组(T2k2)岩芯观察描述及室内粒度分析的基础上,根据沉积相标志确定红山嘴油田红87井区三叠系克上组(T2k2)为辩状河沉积;通过单井划相、剖面相分析及平面相分析,编制出红87井区块三叠系克上组(T2k2)沉积相图,确认了沉积相控制了本区西部含油边界,为断层―岩性油气藏,解决了本区油气藏控制因素。

Sedimentary Facies Characteristics of T2k2 in the Field of Well Hong 87 in the Junggar Basin

Based on the core observation and particle size analysis of T2k2 in the field of Well Hong 87 of the Hongshanzui oilfield in the Junggar Basin, this paper identified T2k2 in the field of Well Hong 87 as the braided river deposits according to sedimentary facies marks. By dividing single well phases, contrasting sections and analyzing plane phases, this paper also presents the map of the sedimentary facies section of T2k2 in the field of Well Hong 87 and has confirmed that a fault-lithologic reservoir is located at the oil boundary in the western region, which is controlled by sedimentary facies. Therefore, the problem of oil-gas reservoir controlling factors has been solved.
