Abstract

Abstract: In recent years, breakthroughs have been made in the exploration and development of shale oil in Northern Songliao Basin. Currently, there is a lack of analysis and summary of the geological conditions for hydrocarbon accumulation and the characteristics of oil and gas reservoirs in Northern part Songliao Basin. To this end, based on the investigation on the exploration and development technologies of shale oil and gas reservoirs at home and abroad, a comparative analysis of six parameters, including burial depth, thickness and reservoir conditions, was performed in combination with the geological and engineering data of shale reservoirs. The results of the study showed that the favorable areas in shale oil and gas reservoirs with high value for commercial development are high pressure shale oil and gas reservoirs rich in organic substances, which are characterized by tectonic stability, high formation pressure coefficient and thick high quality shale. The impact of geological conditions on the development of shale oil and gas reservoirs was also investigated. It was concluded that the degree of thermal evolution, brittleness and burial depth were favorable to the preservation of shale oil and gas, and that drilling and zoning should be done in fractured areas as far as possible to facilitate reservoir stimulation. At the same time, there are some similarities in sequence stratigraphy, geochemical characteristics and production characteristics of shale reservoirs. In terms of development, new technologies and future development of shale oil and gas reservoirs, such as drilling and completion, fracturing stimulation and production optimization, were systematically studied. There is much for reference of the study results to the exploration and development of shale oil and gas reservoirs and large-scale production of Songliao Basin, and to the later selection and well deployment of shale oil and gas zones in Songliao Basin.

Key words: shale oil and gas reservoirs, reservoir conditions, geological conditions, geochemical characteristics, fracturing stimulation, Songliao Basin
