摘要
Abstract
The igneous rocks are widely distributed within the typical rift zone basin of Bohai Bay. Twenty-seven commercial oil traps of igneous rocks have been found in this region up to now, in which twelve are external metamorphic belt reservoirs. The carbonate cement within this kind reservoir has been analyzed isotopically and the results are as δ13C:-6.8‰ to -3.3‰;δ18O:-17.1‰ to -12.5‰, which suggest that the carbonates are deposited by thermally metamorphic dissolution of hydrocarbon generated in the geologic thermal events. The carbon isotopic compositions of the analyzed samples suggest that thermal events would accelerate the generating of hydrocarbon in this area. From this study, the valuable geologic information about filling and special developing history of this kind reservoir, and modeling of the reservoir spaces in this kind of trap should be obtained.关键词
