Yuanbaoshan depression reservoir characteristics and oil accumulation period of
ocksamplesj430O%. 96 Li Linjiang other / Yuanbaoshan depression reservoir characteristics and oil accumulation period of the region Jiufotang the upper part of the upper and lower sample extracts were detected DHVE series, but the distribution is not complete, ~-DHVE, a basic DHVE disappeared or very low (Figure 4),[link widoczny dla zalogowanych], indicating that crude oil source rocks are in R. Evolution to the formation of 0.7 or so. 3 Conclusions (1) Cretaceous reservoir Yuanbaoshan sag experienced two oil and gas accumulation during the first occurred in the late diagenesis, the formation of oil and gas reservoirs Yuanbaoshan main depression,[link widoczny dla zalogowanych], low maturity crude oil,[link widoczny dla zalogowanych], associated with a large number of natural gas. The second occurred in diagenesis,[link widoczny dla zalogowanych], the oil and gas high maturity,[link widoczny dla zalogowanych], the main movement along the tectonic fractures. (2) the use of authigenic illite K-Ar isotopic dating techniques limited the two hydrocarbon accumulation time: 10O ~ 104Ma and 9OMa so. (3) Yuanbaoshan sag of crude oil in Cretaceous reservoirs are mainly low mature crude oil, mixed with a small amount of mature crude oil.
