乌伦古拗陷石炭系烃源岩再认识
The Further Understanding of Carboniferous Source Rocks in Wulungu Depression
摘要
Abstract
Whether Carboniferous source rock develops and its developing stratigraphic position of the real source rock in Wulungu Depression are always in dispute. The Jiangbasitao formation source rocks found in the north of Lun 6 well verify that Carboniferous source rock does exist in this area. The mudstone and the silty mudstone deposited in the shore and shallow sea are the main source rock types. The source rocks are medium-good with the average organic carbon in 1.23%. The type of organic matter is mainly II1 type,which contributes to oil generation. The source rocks are in the high-maturity stage. Some geochemical characteristics including saturated hydrocarbon and aromatic hydrocarbon are that the source rocks are developed in the reductive and brackish water environment. It indicates that the shore and shallow sea is favorable to source rock,which facilitates the abundant source rocks forming and possess good prospects for exploration.关键词
