华池—庆阳地区延长组长6-长7油层组浊积岩特征及成因
Characteristics and genesis of turbidite of Chang 6 and Chang 7 oil reservoirs in Huachi-Qingyang area of Ordos Basin, China
摘要
Abstract
The paper uses the data of drilling cores, logging and seisin in study area to research the turbidite features in detail developed during the deposition of Member 6 and Member 7 of the Upper Triassic Yanchang Formation (Chang 6 and Chang 7) oil reservoirs in the Huachi-Qingyang area of Ordos Basin in China. The features include the bottom cast general development, the obvious flysch rhythms, the typical Bouma sequence, size distribution of paralleling to the C=M baseline, and the Sahu discrimination value of 7. 357. According to the different provenances, the turbidite types are classified as two types: (1) one comes from the northeast gentle slope delta front? (2) another comes from the south and southwest steep slope delta front. Furthermore, based on the above, the paper compares the differences between the two types of turbidite in formation mechanism, size, sand body morphology and litho facies and establishes the genetic model of the turbidite under different depositional settings.关键词
