Gas Condensate is produced from Permian and Triassic marine strata in the southern Sichuan Basin,where the Lower Triassic Jialingjiang Formation is one of the major gas condensate reservoirs.
At the end of the Late Triassic Epoch,influenced by the Indo-China folding movement,Sichuan basin converted from the passive continent margin to foreland basin.
Ordos Basin contains enormous natural gas resources in its lower Paleozoic reservoirs.However,the origin and potential source of the gases are still unclear.
Brittleness index is a most important parameter for hydraulic fracturing and production prediction in the exploration and exploitation of shale gas reservoirs.
The Upper Ordovician is marked by two major global δ13C excursions,the older one is referred to as the Guttenberg carbon isotope excursion(GICE)and the younger one is known as the Hirnantian carbon is
According to the characteristic of lithology,structure,deposition,logging and well completion data,combining with the core observation,we built the geological model of XinChang X5 layer.
