摘要
通过对车排子地区车89井新近系沙湾组研究,表明油藏主要受岩性控制,为滨浅湖滩坝相砂体成藏,纵向岩性组合表现为"泥包砂"特征.地震资料识别出岩性圈闭上下2个层系,分为4个岩性圈闭层组,对各岩性圈闭进行描述,总结出一套准噶尔盆地岩性圈闭识别描述方法,更好的控制该区主力油层分布和连片范围.
Reseach have been studying further that the reservoir in Che89 well Of the chepalzi area is controlled by lithology. The che89 well reservoir is a allimportant finding for Shawan formation of Neogene in Chepaizi area. The reservoir accumulated petroleum by controlled beach and dam of shore and shallow lake facies. There is characteristic of sandstone enveloped shale in vertical lithology compounding. Two formations and four lithology traps found by studying seismic sections. Research had obtained series of methods and processes by studying and describing these lithology traps. This is a foundation for us studying further. The study have gained great effect, another we had further discerned the range and spread of the reservoir sands.
