  • Based on the ratios of Ni/Co, V/Co, Mg/Mn, Mn/Sr, Ba/Mn, Fe/K, Mg/Ca, Ba/Sr, Al/Mg and Al/Na, the provenance of the sandbodies of the upper part of the fourth member of the Shahejie Formation in W58 area, Dongying depression was studied by distribution pattern, provenance index and Qtype cluster. During the period of the upper part of the fourth member of the Shahejie Formation, the south and north provenance systems coexist in W58 area. The deposits in W58 well and its north area were provided by the north provenance system, and the deposits in WX583 and W126 wells and their south area were provided by the south provenance system, and the deposits in the vicinity of N114X1 well have the characteristics both of the south and north provenance. This study shows that the direction of the provenance can be determined more accurately by the use of characteristic elements ratios because the influences of hydrodynamic force and diagenesis can be effectively avoided.

Abstract: Based on the ratios of Ni/Co, V/Co, Mg/Mn, Mn/Sr, Ba/Mn, Fe/K, Mg/Ca, Ba/Sr, Al/Mg and Al/Na, the provenance of the sandbodies of the upper part of the fourth member of the Shahejie Formation in W58 area, Dongying depression was studied by distribution pattern, provenance index and Qtype cluster. During the period of the upper part of the fourth member of the Shahejie Formation, the south and north provenance systems coexist in W58 area. The deposits in W58 well and its north area were provided by the north provenance system, and the deposits in WX583 and W126 wells and their south area were provided by the south provenance system, and the deposits in the vicinity of N114X1 well have the characteristics both of the south and north provenance. This study shows that the direction of the provenance can be determined more accurately by the use of characteristic elements ratios because the influences of hydrodynamic force and diagenesis can be effectively avoided.
