【论文摘要】 经过长期高速注水开发,砂岩油藏的储层孔隙结构发生了较大变化.注入水对储层孔隙、骨架颗粒、胶结物和油藏流体的作用,以及油层温度和压力的变化,使储层渗透率增大, 孔喉半径增大,从而在储层中形成高渗带及特高渗透带,即大孔道.根据油层物理和油藏工程相关理论,建立了五点井网条件下描述大孔道的平均半径 rw 与原状地层毛管的平均半径 ro 关系的数学模型.由于毛管半径是随机变量,因此可用随机模拟方法研究刻画注水开采过程中大孔道的形成规律。推导了详细的数学模拟方法,并给出了一个具体的实例. 该实例结果显示,该模拟方法能够很好地模拟注水开发过程中油藏不同位置大孔道的尺寸分布和位置分布.

【英文论文摘要】 formation pore structure of sandstone reservoirs has changed distinctly after the long-term high speed water-flooding,The effects of injected water to pore structure,rock skeleton granule, bond and reservoir fluids,and the changes of reservoir temperature and pressure,make formation permeability increase,pore throat radius increase,thus high permeability or terribly high permeability zones are come into being in reservoir,namely water channel.In this paper,a mathematical model for the relation of water channels average radii and original formation pore average radii is established to describe the formation of water channels for five-spot pattern in reservoir by using theories of Petrophysics and Reservoir Engineering.pore radii is a stochastic variable ,so forming rules for water channels at some water cut stage can be portrayed by stochastic simulation.,a more specific mathematical method is derived,and an example is given in the paper to demonstrate how to use this model practically,...更多which can be used to simulate changing of water channels size at different locations of the reservoir during water-flooding process,the result shows that the model can simulate the size change of water channels in reservoirs very well during water-flooding.  还原
