The Overlaying Formation Characterization of Lower Paleozoic Group and Analyses to Combination of Reservoirs with Overlaying Formation in Taikang Uplift
-
Abstract
The carbonate rocks in Lower Paleozoic group of Taikang uplift are one of main objective formations in exploration. Bauxitic mudstone on top of Ordovician system, the Benxi group mudstone of carboniferous system, the mud shale of Cambrian system,"Jiawang shale" on bottom of tight carbonate rock can all regard as overlaying formation of objective formation for exploration in differential grade. These objective formation exist 3 group combinations of reservoirs with overlaying formation, and unitized relationship is better.
