Abstract

Abstract:

The isotopes of carbon,oxygen and strontium,REE,and the geochemical features of the fluid inclusions in the Middle-Upper Cambrian and Middle-Lower Ordovician side-beds and fracture fillings of the well Yingdong-2 were systematically analyzed.Based on the results,we traced phases and sources of the reservoir fluids,determined chronogenesis of fluid charging,explored the impact of the fluids upon reservoir modification and discussed the dynamic preserving conditions for oil and gas in such settings.The geochemical study of the fluids suggests that there are three charging phases of allogenic fluids with abundant Sr from the crust in the Middle-Upper Cambrian and Middle-Lower Ordovician .The fluids charged in the first phase have a ⁸⁷Sr/⁸⁶Sr ratio of 0.710 8,the fluids charged in the second phase have a ⁸⁷Sr/⁸⁶Sr ratio in the range of 0.709 8-0.710 0,and the fluids charged in the last phase are hydrothermal fluid from the deep crust and have a ⁸⁷Sr/⁸⁶Sr ratio of 0.713 8.The fluids charged in these three phases all played a destructive role in the forming of reservoirs,but the hydrothermal fluids charged in the last phase were constructive to the reservoir formation.The Middle-Upper Cambrian reservoirs had relatively better hydrocarbon preserving conditions during the first phase of fluid charging,but lost them when the second and the third phase occurred.Geochemical tracing of fluids provides a new method for dynamic evaluation of deep fluid activities in the Yingdong tectonic belt as well as the whole eastern Tarim Basin.
