摘要

摘要: 四川盆地寒武系龙王庙组时代老，埋藏深，储层埋藏及成岩改造强烈，且受加里东、印支、喜马拉雅等重要构造运动的影响，油气成藏过程复杂。通过对龙王庙组岩心观察、岩石学类型分析、显微薄片的观察，结合阴极发光特征对成岩矿物的充填序列进行了识别和划分。以矿物的充填序列为基础，对不同期次成岩矿物中赋存的烃类流体包裹体特征进行了分析，对与其共生的盐水包裹体的均一温度进行测试，明确了龙王庙组油气藏的成藏期次，并结合安岳构造龙王庙储层热演化史，厘定了油气成藏时间。所识别出的5期白云石以及石英等成岩矿物捕获的流体包裹体，记录了5期油气成藏事件：第一期为中三叠世的古油藏充注；第二期为早侏罗世的古油气藏充注；第三期为中侏罗世的湿气藏充注；第四期为早白垩世晚期的干气藏充注；第五期为晚白垩世以来的气藏调整。喜马拉雅构造运动期的古气藏调整是龙王庙组气藏形成的重要时期，对应的时间约为40 Ma。

Abstract: The Cambrian Longwangmiao Formation in the Sichuan Basin is old, deeply buried with extensive diagenetic transformations, which was affected by important tectonic movements such as Caledonian, Indosinian and Himalayan, so that the hydrocarbon accumulation process is complex. The mineral diagenesis sequence of the Longwangmiao Formation was determined by core observation, petrological type analysis and thin section observation combined with cathodoluminescence characteristics. The characteristics of hydrocarbon fluid inclusions in different diagenetic minerals were analyzed, and the homogenization temperature of symbiotic brine inclusions was tested to clarify reservoirs in the Longwangmiao Formation based on the sequence of mineralization. Combined with the thermal evolution history of the Longwangmiao reservoir in Anyue, the hydrocarbon accumulation periods and time were determined. The results showed that the identified fluid inclusions captured by five diagenetic minerals, such as dolomite and quartz, recorded the five stages of hydrocarbon accumulation events. The first stage is the Middle Triassic filling, the second stage is the Early Jurassic filling, the third stage is the Middle Jurassic wet gas filling, the fourth stage is the late period of Early Cretaceous, and the fifth stage of dry gas filling is the adjustment of the gas reservoir since the Late Cretaceous. The adjustment of gas reservoirs during the Himalayan tectonic movement is an important period for the formation of Longwangmiao Formation gas reservoirs, which is about 40 Ma.
