| Abstract: | the Leikoupo formation in Longmen Mountain in western Sichuan is located in the hidden structural belt in front of the mountain, and the reservoir belongs to the sedimentary characteristics of the limited platform tidal flat phase during the transgression period. The reservoir develops micro-powdery dolomite, algae dolomite reservoir, and mesoporous ultra-low permeability reservoir dominated by dolomite pore type and dolomite fracture-pore type. The detailed study has important guiding significance for the exploration breakthrough of Lei Si gas reservoir in Longmen Mountain front of western Sichuan and the submission of 100 billion square reserves packed gas field. |
