Abstract

Abstract:

Luzhou palaeohigh can be divided into 3 parts,including core,slope and periphery.The core of the palaeohigh is dominated by gas reservoirs in the first member of Jialingjiang Formation,the slope on the northern edge is dominated by gas reservoirs in the second member of Jialingjiang Formation,and the slope on the southern edge is dominated by multilayered gas reservoirs in the third member of Jialingjiang Formation.The properties of gas in Jialingjiang Formation in Luzhou palaeohigh are complex,i.e.there are both the wet gas with condensate oil as that in the core of the palaeohigh and the dry gas without condensate oil as that in the slope zones of the palaeohigh. Based on geochemical analysis of total hydrocarbon by using gas composition and biomarkers,gas in the core of the palaeohigh has mainly been sourced from the Jurassic source rocks with some from the Upper Permian Longtan Fm coal-measure source rocks,while that in the slope zone has mainly been sourced from the Lower Permian carbonate source rocks with some from the Upper Permian Longtan Fm coal-measure source rocks.Oil and gas reservoirs in Jialingjiang Fm in Luzhou palaeohigh have been formed in 4 stages: formation and destruction of fossil oil reservoirs in the core of the palaeohigh during Indo-Chinese epoch;formation of gas reservoirs with some oil in the core of the palaeohigh during Early-Middle Yanshanian epoch;formation of dry gas reservoirs in the slope zone at the end of Yanshanian epoch;and further enrichment and adjustment of gas reservoirs during Himalayan epoch.The evolution of Luzhou palaeohigh controlled the distribution of the oil and gas reservoirs in Jialingjiang Fm;plenty of multistage and multi-source oil and gas charging was the material base of oil and gas reservoiring;"faults connecting the source rocks" controlled the level of oil and gas enrichment;later development and enlargement of dissolution pores determined the reservoiring capability of gas reservoirs;the solid bitumen and asphaltene in the core of the palaeohigh provided the sealing conditions,as well as ensured oil and gas enrichement.

Key words: fossil oil reservoir, reservoir space, reservoiring geochemistry, Jialingjiang Formation, Luzhou palaeohigh, Sichuan basin
