泌阳凹陷梨树凹区块油气成藏期次与成藏过程
Hydrocarbon Accumulation History and Process in Lishuwa Block, Biyang Depression
摘要
Abstract
Located in southern steep slope of Biyang Depression,Lishuwa Block is formed by late reversal extrusion of the fracture extensional fault depression at the eastern boundary and then by uneven uplifts of the late sag.The reservoirs in this area are mainly sand bodies of Houzhuang braided river delta front,belonging to media-porosity and media-permeability reservoir.Oil-source correlation shows that the oil and gas were mainly from the same formation source rocks of the furrow area,where there is obvious mixed source.Based on the microscopic characteristics of the brine inclusions,homogenization temperatures,and combined with typical wells' burial history,thermal evolution history,this paper reveals that there are mainly two hydrocarbon accumulation stages.Specifically,the end of Eh1 is the minor accumulation period with a small-scale oil and gas migration loss,and the later Liaozhuang stage is the main accumulation stage with mass oil and gas accumulation.During the period,the mature oil & gas of Eh3 and the immature-low mature oil & gas of Eh2 were injected into the upper part of the core.关键词
