摘要: 以沉积层序油气运移期的古构造形态为边界条件,系统考虑沉积层序内部与流体运移有关的参数(储集层厚度、孔隙度、渗透率、压力等),在划分流体运聚单元的基础上,依据流体从高势区向相对低势区运移的普遍规律,采用Petro Charge系统模拟流体运移轨迹,以此来评价处于含油气沉积盆地斜坡带等非有利构造位置的岩性圈闭接受流体的能力,通过分析岩性圈闭在流体势场中的位置来综合评价其含油气性。通过在江汉盆地潜江凹陷和吐哈盆地胜北洼陷的应用,初步证实了该方法在岩性圈闭含油气性综合评价方面的辅助参考作用。Abstract: With the boundary of paleo-structural map of sedimentary sequence in fluid migration period,systematically taking into consideration the coefficients(such as reservoir thickness,porosity,perme-ability and pressure,etc.) pertained to fluid migration within sedimentary sequence,based on the division of migration-accumulation units,abiding the regularity that fluid migrates from higher potential area to the lower one,using the modeling software of Petro Charge to model the trace of fluid migration,the fluid-containing ability of lithologic traps on slopes in oil-and-gas bearing basins is finally evaluated.The applications in the Qianjiang Sag of the Jianghan Basin and the Shengbei Sag of the Tuha Basin show that,fluid potential analysis is an effective ancillary approach in oil-and-gas bearing evaluation of litho-logic traps.
