通过对准噶尔盆地阜东斜坡带侏罗系三工河组的岩性组合、粒度分析和地震反射特征等方面的研究,认为储油砂体主要为浊积岩,岩性为灰色泥岩、灰色中砂岩和灰色粗砂岩夹砂砾岩.岩石成份成熟度和结构成熟度均较低,见典型鲍马沉积序列,浊积扇是不稳定三角洲前缘砂质沉积物向坡折带及深水盆地的再分配的结果.研究该区具有多个浊积扇体,其中阜16井已获得低产油气流,说明阜东斜坡带具有良好的勘探前景.

The integration of lithologic assemblage, core, grain size and seismic reflection data on the Jurassic strata in the Sangonghe Formation in the eastern Fukang slope zone, Junggar Basin, Xinjiang has disclosed that the reservoir sandstones dominantly consist of turbidites including grey mudstone, grey medium- to coarse-grained sandstone intercalated with sandstone and conglomerate with low compositional and textural maturity and typical Bouma sequences. The turbidite fans in the study area resulted from the redeposition of the unstable delta front sandy sediments in the slope break zone and deep-water basin, and may be highly prospective for the oil-gas exploration.
