摘要
渗吸注水是低渗透裂缝性油藏注水开采的重要机理,合理的注水方式与注水参数对改善低渗透裂缝性油藏水驱开发效果具有指导意义。通过大量的室内实验研究,获得了大安寨油藏基质岩块自然渗吸动态规律和脉冲渗吸动态规律,为制定合理的油藏渗吸注水开发方式提供了理论依据。
Water imbibition injection is an essential mechanism of the oil production in low permeability fracturing reservior. Reasonable water injection mode and injection parameters have instructive meaning in improving the development efficiency of low permeability fractured reservior. By a good number of experiments, the dynamic law of natural water imbibition injection and pressure-pulse water imbibition injection for Da'anzai low permeability fracturing reservior were obtained, which can provide theoretical and technical support for reasonable water imbibition injection mode of the reservior.
