Applied Mechanics and Materials, 2010 Sedimentary microfacies of Ⅳ sand group of the second member of Qingshankou formation in Daqingzijing area are interpreted jointly with careful core description, sequence and distribution of sandstone. The area also develops delta. Sedimentary microfacies shows that sand body size is becoming smaller and in the transgression period of Ⅳ sand groups of ...

Ostracod Biostratigraphy of the Late Cretaceous Qingshankou Formation in the Songliao Basin
Acta Geologica Sinica, 2007Abstract: An ostracod biostratigraphic study was performed on 425 samples from the composite geological section constructed by using cores taken from five selected wells drilled in the Late Cretaceous Qingshankou Formation in the Songliao basin. A total of 19 ostracod zones are established in the formation, of which 3 are newly established and 3 are ...

Abstract The study of sedimentary pyrite morphological characteristics provides useful information on depositional environments and early diagenic processes and can be used as an indicator of redox conditions in ancient lake bottom waters. The results of this study in the Songliao basin in northeastern China show that euhedral crystals and framboids ...

Comparison of Qingshankou Formation in Songliao Basin with Bakken Formation in Williston Basin
Advanced Materials Research, 2014Based on geological background, this study is to understand the potential of tight oil of Qingshankou Formation in Songliao Basin by comparing lithofacies features, oil-generating conditions and reservoir characteristics. Hundreds of samples are analyzed to derive geochemical parameters, such as organic richness, kerogen type, and source rock maturity.

ABSTRACTAnalysis of accommodation space variation during deposition of the Cretaceous Qingshankou Formation in the Songliao Basin, NE China, indicates that accommodation space changed both through time and across the basin as a seesaw movement. The mid‐upper Qingshankou Formation is divided into three units. In each unit, changes of accommodation space

The Movable Resource Volume Evaluation of Qingshankou Formation Shale Oil in Northern Songliao Basin
Advanced Materials Research, 2013Northern Songliao Basin contains a large amount of oil shale resources. Due to the limitation of the oil and gas enrichment area, movable oil and gas and mining conditions, must determine the advantageous area of movable resource. Based on the improved Δ logR model, evaluated the organic matter abundance and residual hydrocarbon content; Based on the ...
