Experimental Investigation of Seepage Mechanism on Oil‐Water Two‐Phase Displacement in Fractured Tight Reservoir

Geofluids, Volume 2022, Issue 1, 2022., 2022
As a type of unconventional oil and gas resources, tight sandstone reservoir has low permeability and porosity properties and thus is commonly necessary to develop through hydraulic fracturing treatment. Due to the coexistence of natural fractures and induced hydraulic fractures, the heterogeneity of reservoir permeability becomes severe and therefore ...

Chemically Active Elements of Reservoir Quartz Cement Trace Hydrocarbon Migration in the Mahu Sag, Junggar Basin, NW China

Geofluids, Volume 2021, Issue 1, 2021., 2021
Element exchange and enrichment during fluid‐rock interactions are common, providing potentially novel proxies to trace hydrocarbon migration in addition to the traditional organic geochemistry tracers. However, the processes, mechanisms, and geological and geochemical fingerprints of these interactions are complex, hampering the applications of ...

Potential Source Regions and Transportation Pathways of Reactive Gases at a Regional Background Site in Northwestern China

Advances in Meteorology, Volume 2021, Issue 1, 2021., 2021
Reactive gases (O3, CO, NO2, and SO2) were collected hourly at the Akedala regional background station in northwestern China during September 2017 to August 2018. Wind rose, cluster analysis, potential source contribution function (PSCF), and concentration‐weighted trajectory (CWT) methods were adopted for identifying the transport pathways and ...

Sequence architecture, slope-break development and geological significance during the P–T transition in the Mahu Sag, Junggar Basin, China

Journal of Natural Gas Geoscience, 2022
During the P–T transition period (from the Late Permian to the Early Triassic), the Mahu Sag of the Junggar Basin transitioned from a foreland basin to a large depression lake basin, with the development of two sets of unconformities (T1/P and P3w/P2w ...
