摘要:
针对真武油田主力断块已经进入高含水、高采出程度的现状,利用岩心样品进行了室内测试,结合监测资料,研究了长期注水冲刷以后原油粘度、渗透率、孔隙度、相对渗透率曲线、润湿性等参数的变化。研究结果表明,真武油田主力断块经过长期水驱冲刷以后,原油的粘度、密度缓慢变大,孔隙度变化较小,渗透率变化较大,且渗透率越高,变化越明显; 并且长期水驱冲刷对储层的渗流特征产生影响,润湿性表现为亲水性增强; 在油水相渗曲线上表现为油水两相等渗点向右偏离。
Abstract:
Aiming at the fact that main blocks in Zhenwu Oilfield have entered the high water-cut stage and high recovery degree,combining with dynamic monitoring data,using core samples,an experiment study was conducted on parameter changes in oil viscosity,permeability,porosity,relative permeability curves and wettability after long-term water flooding.The experimental results showed as follows:(1)after long-term water flooding,the oil viscosity and density became more and more large,the porosity change was smaller,and the permeability change was obvious.In other words,the higher the permeability was,the more obvious the permeability change was;(2)the long-term water flooding has a certain effect on the percolation characteristics of reservoir,water wettability was increased,and the equal permeability point on the oil-water relative permeability curve moved to the right side.
