SEDIMENTARY CHARACTERISTICS OF FUYU OIL LAYERS IN CHAOCHANG REGION OF SONGLIAO BASIN
摘要
Abstract
Accurate understanding of the characteristics of reservoir sedimentation is the material base for the petroleum reservoir evaluation. By means of the principle of high-resolution sequence stratigraphy, the sequence interface , lake flooded plane and the rise-and-drop cycles of the base level are recognized with the help of the properties stratigraphic petrology and geophysics. In Chaochang region of Songliao Basin, Quan No. 3 & 4 Members are divided into 1. 5 three-grade sequences corresponding three rise-and-drop cycles of the base level; and once more they are classified into 7 four-grade sequences corresponding fourteen rise-and-drop cycles of the base level. Finally the isochronal sequence stratigraphic framework is established and the problem of corresponding relation between the oil reservoir group and sequence formations is solved at last. On the basis of isochronal sequence classification, the typical sedimentary facies forms of meandering river, delta, lake and so on are determined; the material source from southwest direction is pointed out in the region. The reservoirs are mainly meandering river channel sandbodies distributed along NE strike and stacked during many periods.关键词
