柴达木盆地北缘地区第三系碎屑岩储层沉积相特征
CHARACTERISTICS OF TERTIARY RESERVOIR SEDIMENTARY FACIES IN THE NORTH PART OF QAIDAM BASIN
摘要
Abstract
The north part of the Qaidam basin is one of the three oil-bearing units in Qinghai oilfield. The Tertiary reservoirs are mainly distributed in the strata from low-Gancaigou formation to low-Youshashan formation. The former research on Tertiary sedimentary facies determined that fluvial and flood plain are the main facies. A comprehensive study on petrology, structures, facies models, facies associations and sedimentary systems in this paper shows that the main facies in Tertiary are shore-lake and shallow-lake subfacies, and lake delta facies from low-Gancaigou formation to low-Youshashan formation. This new conclusion is very important in theory and economics during the course of calculating the geological reserve of Tertiary.关键词
