Palaeogeographic characteristics and basic geological conditions of petroleum of the Carboniferous in Junggar Basin and its adjacent areas
摘要
Abstract
It has the double basement of the Precambrian metamorphic crystallization basement and fold basement in Junggar Basin and its adjacent areas.The Carboniferous was the first full strata and developed well in the study area.Under the instruction that the tectonic controls a basin's development, while the latter controls facies,the sedimentary facies and lithofacies palaeogeographic characteristics in the study area was analyzed as followduring the Early Carboniferous,the sedimentary basins,with active or passive continental marginal marine facies or land-ocean transitional facies,were formed;while in Late Carboniferous,the sedimentary basins of land-ocean transitional facies and the continental volcanic build-ups were developed.Generally,the Carboniferous was divided into three zones of marine,land-ocean transitional,and continental facies;detailedly,8 types of facies were identified,i.e.,continental,marine volcanic and pyroclastic,bathyal-abyssal,neritic,littoral,deltaic,fluvial-lacustrine,and the alluvial-fan facies.Based on the idea that “the sedimentary facies controls the basic geological conditions of petroleum”,the petroleum distribution in Junggar Basin is concluded a(1 )For the Karamay-Baijiantan areas in the northwestern margin,and the Bayingou and Urumqi in the southern margin,it develops bathyal-abyssal dark muddy shales,which are supposed to be relatively good source rocks;(2) The delta facies which are favorable developed in the southeast-northern margin of Junggar Basin,such as the areas of Karamay are the advantageous zone of oil and gas exploration,and the source rocks and reservoir rocks were developed well.(3)The tidal-flat facies and lagoon facies which are favorably developed in the Santanghu area,as well as the neritic carbonate- clastic shelf facies which are favorably developed in the Burerjin-Fuyun and Bogeda mountain areas can form a relatively good assemblage of source-reservoir-cap. These sedimentary facies and zones where source,reservoir and cap rocks distributed trinity are the optimum targets and the top choice areas.关键词
