摘      要：Reconstruction of the diagenetic evolution of reservoirs is one of the most significant tasks in oil and gas exploration and *** the accurate timing of diagenetic events is critical to better understand the process of reservoir evolution,but the isotope dating of diagenetic events is technically *** paper uses three case studies in the sedimentary basins in China to demonstrate the promising application of recently developed LA-(MC)-ICPMS in-situ U-Pb *** results show that the new U-Pb dating method provides a reliable and efficient chronological approach to determine the absolute ages of diagenetic *** example,the U-Pb age data of the Cambrian carbonate reservoir in the Tarim Basin reveals three diagenetic events at 526±14,515±21,and 481±4.6 Ma,*** is worth noting that microscopic observations are particularly important for improving the success rate of U-Pb *** addition,the recent progress and future prospects in the in-situ U-Pb dating method are also discussed in this study,suggesting that this method is currently hindered by the lack of international carbonate standards for data correction.
