A new method for reconstructing the geological history of hydrocarbon accumulation is developed, which are constrained by U-Pb isotope age and clumped isotope (Δ₄₇) temperature of host minerals of hydrocarbon-bearing inclusions. For constraining the time and depth of hydrocarbon accumulation by the laser in-situ U-Pb isotope age and clumped isotope temperature, there are two key steps: (1) Investigating feature, abundance and distribution patterns of liquid and gaseous hydrocarbon inclusions with optical microscopes. (2) Dating laser in-situ U-Pb isotope age and measuring clumped isotope temperature of the host minerals of hydrocarbon inclusions. These technologies have been applied for studying the stages of hydrocarbon accumulation in the Sinian Dengying gas reservoir in the paleo-uplift of the central Sichuan Basin. By dating the U-Pb isotope age and measuring the temperature of clumped isotope (Δ₄₇) of the host minerals of hydrocarbon inclusions in dolomite, three stages of hydrocarbon accumulation were identified: (1) Late Silurian: the first stage of oil accumulation at (416±23) Ma. (2) Late Permian to Early Triassic: the second stage of oil accumulation between (248±27) Ma and (246.3±1.5) Ma. (3) Yanshan to Himalayan period: gas accumulation between (115±69) Ma and (41±10) Ma. The reconstructed hydrocarbon accumulation history of the Dengying gas reservoir in the paleo-uplift of the central Sichuan Basin is highly consistent with the tectonic-burial history, basin thermal history and hydrocarbon generation history, indicating that the new method is a reliable way for reconstructing the hydrocarbon accumulation history.

用于重构烃积聚的地质历史的新方法的发展，其通过U形铅同位素年龄和结块同位素（Δ约束₄₇) 含烃包裹体的寄主矿物的温度。通过激光原位 U-Pb 同位素年龄和成簇同位素温度约束油气成藏时间和深度，有两个关键步骤： (1) 用光学显微镜研究液态和气态烃包裹体的特征、丰度和分布模式. (2) 激光原位U-Pb同位素年龄定年及烃类包裹体寄主矿物成簇同位素温度测定。这些技术已应用于川中古隆起震旦系灯影气藏成藏阶段研究。通过测定 U-Pb 同位素年龄并测量成簇同位素的温度 (Δ ₄₇) 的白云岩油气包裹体的寄主矿物，确定了三个阶段的油气聚集： (1) 晚志留世：石油聚集在(416±23) Ma 的第一阶段。(2)晚二叠世至早三叠世：(248±27)Ma至(246.3±1.5)Ma之间的第二阶段油藏。(3)燕山至喜马拉雅时期：气藏在(115±69)Ma～(41±10)Ma之间。川中古隆起灯影气藏重建成藏史与构造埋藏史、盆地热史、生烃史高度吻合，表明新方法是重建川中古隆起的可靠途径。油气成藏历史。
