摘要
在落实吐哈盆地西山窑组构造及沉积演化过程的基础上,通过岩心观察和描述以及岩屑录井、分析化验资料的综合研究,从区块不同时期的岩石学特征、砂岩厚度、砂岩百分含量以及泥岩颜色平面变化等方面对物源进行分析。综合分析表明:鄯善油田西山窑组时期整体为南部物源,且距离物源区较远。东南方向为主要物源供应方向,西南方向为次要物源,且在沉积的不同时期,物源方向有所迁移和变化。
With Tectonic and sedimentary evolution process of Xishanyao Formation of Tuha oilfield in mind, based on core observation, logging curves and analytical and testing data, the provenance was determined according to the petrologic feature, sandstone thickness, sand content and mudstone color zoning of different periods. The result show that the main sediments were mainly derived from southern, and far from the provenance. The southeast was the main provenance, while the southwest was secondary provenance, and the provenance during the whole Xishanya changed with time.
