Reservoir characteristics and diagenetic facies of Chang 63 sub-member in Huaqing area, Ordos Basin
Online published: 2011-08-20
The debris flowchannel deposits of sublacustrine fan of Chang 63 sub-member in Huaqing area, Ordos Basin are fromdifferent provenances, which could be divided into three parts, including the dominant northeast and southwest sources, and the minor mixed source. Based on the composition, diagenesis, and the differences and zones of plane diagenetic facies distribution ofChang 63 sandstone reservoir, it is determined that the provenances are the main factors that control the reservoir distribution. The chlorite cementation-intergranular pore diagenetic facies controlled by northeast provenance and the chlorite cementation-intergranular pore and feldspar dissolution diagenetic facies controlled by the western mixed source are the most favorable depositional-diagenetic facies zones. The research results can provide references for reservoir evaluation and development in Huaqing area.
