Abstract

Abstract

Uplift is one of the major patterns of tectonic movement in sedimentary basin. Its contribution to reservoir is neglected before, but the damage function is emphasized. Based on the rebounding simulation of sandstone by using different grain level sandstones under conditions of different temperatures and pressures, the quantitatively rebounding chart of sandstone in different geological conditions during uplift is established. Taking the Daqing placanticline as a typical example, the quantitative relationship between sandstone rebounding and reservoir formation was established based on integrated analysis of buried history, hydrocarbon generation and expulsion history. The contribution ratio due to rebounding of sandstone during uplift is 13.43%-40.46% in the Daqing placanticline. The new method provided in this paper can offer more scientific basis for forecasting hydrocarbon distribution.
