Abstract:
Significant breakthroughs have been made in shale oil exploration in the second member of Funing Formation in Qintong sag of Subei Basin. The sweet spot intervals are composed of deep lacustrine shale reservoirs, which exhibit strong heterogeneity, limiting the effective prediction of sweet spot distribution and resource potential evaluation. To clarify the lithofacies diversity and genetic mechanisms of deep lacustrine shale within the sweet spot intervals, multiple research methods, including key well core analysis, thin section observation, whole-rock X-ray diffraction(XRD), and automated quantitative mineralogical analysis, were employed to analyze the shale lithofacies types, genetic mechanisms, and controlling factors. The results show that according to the lithofacies classification criteria of mineral composition and sedimentary structure, the target interval of shales in the study area can be categorized into five main types, including massive mudstone facies, thin-laminated shale facies, thick-laminated shale facies, deformed-laminated shale facies, and cross-laminated shale facies, and these primary facies are further subdivided into 14 subtypes; facies association indicates that various fine-grained sedimentary processes occur in the deep lacustrine settings in the second member of Funing Formation, including suspension, flocculation, and chemical precipitation in still water, deep-water fine-grained gravity flows with rheological variations, frequent paleo-seismic activity, and substantial reworking by lake-bottom currents; the spatial variation of deep sag and fault scarp is strongly related to the elongated structure of the small lacustrine rift basin and the transport distance of terrigenous detrital materials.
