Abstract

Abstract

As a key exploration area for Silurian shale gas in southern Sichuan basin, Ningxi area experienced multiple fracture activities. Calcite veins are generally developed in the Longmaxi Member I. At the same time, graphitization occurs due to the extremely high degree of thermal evolution, resulting in shale gas enrichment pattern which remains unknown. This paper presents an estimation of paleotemperatures and paleopressures of the key exploration well in the region-the Well Ningxi 202 of Longmaxi Member I, through integrated analyses on systematic core description, thin section microscopic observation, cathodoluminescence observation, laser Raman spectroscopy, and microscopic temperature measurement. Results show that: High-angle calcite veins (type A) are distributed in the main body of the Longmaxi Member I, and bedding veins (type B) are locally developed. Methane inclusions are mainly developed in Type A veins, and some samples show special bitumen inclusions. The _RmcR_o of bitumen in bitumen inclusions are 3.52%-4.16%, indicating that they are in the overmature to graphitization. The methane Raman scattering peak is between 2 910.711 2-2 912.495 1 cm^-1, with the homogenization temperature between -99.8 to -96.3℃. The density obtained by Raman parameter displacement and microscopic temperature measurement ranged from 0.253 6-0.344 5 g/cm³ and 0.291 6-0.303 2 g/cm³, showing typical high-density characteristics. In conclusion, the high density methane inclusions may be trapped in the early stage of Yanshan tectonic movement and in overpressure state, indicating that the shale system has good sealing property and is conducive to shale gas enrichment.
