Analysis of the provenance and lithofacies palaeogeography sedimentary facies in Simen formation in the lower Carboniferous in Guizhong area
摘要
Abstract
Guizhong depression, large scale late Paleozoic marine residual basin that formed basically in the stable craton of late Paleozoic to Mesozoic, indicates excellent oil and gas accumulation and exploration potential.Several exploration drilling operations reveal that the generation of the sand reservoir has well matched with the source rock and was covered by finely tight layers in Simen formation in the lower Carboniferous in host area.There are several major discoveries in this type of clastic reservoir in the lower Carboniferous in China, such as Tarim and Ordos basin.In the background of unclear exploration area, the study on this new type of reservoir with great potential is significant strategic.Based on research of the regional geology and analysis of geological and geophysics materials, it worked out that there were 3sources zones, zoneⅠ was mainly located in Nandan and Huanjiang areas in the northwest of Guizhong, zoneⅡ was mainly located in Liucheng and Luzhai areas in the eastern part of Guizhong, and zoneⅢ was the mixed source area.In addition, the mother rock of sandrock came from the Xuefeng landmass in north and the Yunkai landmass in east.There were delta facies near landmass and sand dam distributed in the leading edge area that influenced by ancient landforms, tides and waves.The research results provide guidance for oil and gas exploration evaluation in host area.关键词
