| 摘 要： | 塔河油田奥陶系碳酸盐岩缝洞型储层为该区最重要的油气生产层段.依据地质岩心(屑)、录井、钻井、测井、地震等多种资料,运用由点到线再到面的方法,探讨了塔河油田奥陶系碳酸盐岩油藏的溶洞发育规律.由区内溶洞充填砂泥岩的伊利石K-Ar同位素定年,得出其形成时间在369.33～451.90Ma,古溶洞的形成时间应该早于该时段或与该... |

| Abstract: | Ordovician carbonate fissuring/cavernous reservoirs are the important oil pay beds in Tahe Oilfield.Based on the K-Ar isotopic dating for illite from sandstone and mudrock filling in the karstic caverns of the reservoirs,the formation time of cave-fillings is during 369.33-451.90Ma and thus that of the paleocaverns should be earlier than or equal to the 369.33-451.90Ma,which is corresponding to the late Caledonian-early Hercynian periods.There are three vertical cavern zones in Tahe area.Paleocavern develop... |
