New understanding of the sedimentary model of Lower Cambrian Longwangmiao Formation reservoirs in the Sichuan Basin

Natural gas in the gas reservoirs of Lower Cambrian Longwangmiao Fm is mainly concentrated in the granular shoal facies in central Sichuan Basin, therefore the study on lithofacies paleogeography and the prediction on granular shoal distribution are the key to improving the success ratio of natural gas exploration in this area. In this paper, outcrop, drilling, seismic and logging data were studied comprehensively. Subsequently, the sedimentary...
