松辽盆地北部青山口组页岩油形成地质条件及勘探潜力

Abstract

Abstract: Shale oil and gas is one of the most important resources to replace the conventional oil and gas.According to regional geological surveying,the geological conditions of the development of shale oil in northern Songliao Basin were studied in this paper.Also,the favorable target intervals were selected and their potentials of exploration were assessed.The Qingshankou Formation has obvious cyclicity due to the control of lake level change,with mudstone rich in organic matter and gray matter and silty mudstone appearing alternately.The dark mudstone in the lower subcycle is characterized by large single layer thickness,broad distribution area and high content of organic matter,and is still at the stage of hydrocarbon generation.The upper subcycle is characterized by enrichment of quartz-feldspathic minerals and ultra-low porosity and permeability.Many micro pores and cracks are observed in scanning electron microscope,and they offer reservoir space for oil and gas.In addition,the shale reservoirs in K₁qn¹ are heterogeneous and mostly have abnormal pressure,thus are favorable for the shale oil accumulation.Geochemical analysis data and isothermal adsorption test of shale interval show that the 1st member of Qingshankou Formation is richest in oil,and contains some gas.So it has the larget exploration potential for shale oil exploration.Based on the above-mentioned geological conditions and oil-gas-bearing possibility study,the space distribution of favorable reservoir in K₁qn¹ is determined,and the OOIP of shale oil is calculated to be 10.56 billion tons by using probability volume method.

Key words: isothermal adsorption, probability volume method, reservoir property, shale oil, Songliao Basin
