Pyrite morphology in the first member of the Late Cretaceous Qingshankou Formation, Songliao Basin, Northeast China

Palaeogeography, Palaeoclimatology, Palaeoecology, 2013
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 ...

Forward Simulation of Single Subaqueous Distributary Channel Sand Bodies of Qingshankou Formation (Cretaceous) in South Songliao Basin

2021
The classification of single channel sand bodies within composite subaqueous distributary channels of a non-dense well area/zone is one of difficulties in geological research for oilfield development. In this study, the distribution of single channel sand bodies within composite subaqueous channels of the third member of the Qingshankou Formation in ...

Study on Sedimentary Macrofacies of Sandy Group V of the Second Section of Qingshankou Formation, Daqingzi Region

Applied Mechanics and Materials, 2010
According to the core observation and log facies analysis, in the stage of the sand group V of the second section of Qingshankou formation, it mainly develop the delta of type IV which was proposed by Coleman and Wright and in Daqingzi region ,the delta can be classified into two subfacies : delta front and prodelta. The delta front can be divided into

Sedimentary Facies Study for IV Sand Group of the Second Member of Qingshankou Formation in Daqingzijing Area

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 ...

Pore-scale oil distribution in shales of the Qingshankou formation in the Changling Sag, Songliao Basin, NE China

Marine and Petroleum Geology, 2020
Abstract A total of 19 representative lacustrine shale (core) samples from the Upper Cretaceous Qingshankou Formation in the Changling Sag, Songliao Basin, northeast China have been characterized to determine the types of shale oil reservoir lithofacies and investigate pore structures and pore-scale oil distribution using an integrated petrographic ...

Study on the Cretaceous turbidite and reservoir features in the Qingshankou Formation in northern Songliao Basin, NE China

Marine and Petroleum Geology, 2016
Abstract Based on analysis of well and drilling data, cores, sediment grains and 3D seismic data, four types of turbidites–slope fan, channelized, laminated and sublacustrine fan turbidite–are identified in Members 1 and 2 of the Qingshankou Formation in northern Songliao Basin. The slope fan turbidite is located in Members 1 and 2 of the Qingshankou

High resolution geochemical analysis of organic matter accumulation in the Qingshankou Formation, Upper Cretaceous, Songliao Basin (NE China)

International Journal of Coal Geology, 2015
Abstract In the well-known continental Songliao Basin, the oil shale successions of the Cretaceous Qingshankou Formation are excellent source rocks for oil. The oil shale layers with high TOC (total organic carbon) contents developed at the bottom of the formation.

Geochemical characterization of source rocks and crude oils in the Upper Cretaceous Qingshankou Formation, Changling Sag, southern Songliao Basin

Marine and Petroleum Geology, 2015
Abstract The Upper Cretaceous Qingshankou Formation is one of the main exploration target in the Changling Sag, southern Songliao Basin. However, the origin of source rock deposition and crude oils remains undiscovered. A comprehensive geochemical study, including Rock–Eval pyrolysis, gas chromatography-mass spectrometry and carbon isotope analysis ...

Hydrocarbon micro‐migration and differential enrichment mechanism of shale oil in upper Cretaceous Qingshankou Formation in Songliao Basin

Geological Journal
Shale reservoir has strong heterogeneity in mineral composition and oil content even at a short distance in the same interval. To better understand the accumulation mechanism of shale oil and hydrocarbon migration tendency in the interval, and explore the main influencing factors of distribution.
