采用动态拟合方式研究了新疆准噶尔中部X区块低渗储层油相和水相的启动压力梯度以及渗透率、粘度等因素对储层启动压力梯度的影响。结果表明,流体在多孔介质中流动的启动压力梯度随渗透率的降低呈指数方式增大,随流体的粘度的增大近似线性增大。这对于存在一定的应力敏和高油气比、高饱和压力的油藏,一定要慎重采用放大生产压差的开采方式;建议在开发过程中合理采取早期注水、周期开采以及酸化压裂等措施和方法。 The dynamic fitting method was used to study the influence of start-up pressure gradient, permeability and viscosity on the initial pressure gradient of the reservoir in the X-block of central Junggar in Xinjiang. The results show that the starting pressure gradient of fluid flow in porous media increases exponentially with the decrease of permeability and increases linearly with the increase of fluid viscosity. This should be careful to adopt the method of enlargement and production differential pressure for reservoirs with certain stress sensitivity and high oil-gas ratio and high saturation pressure. It is suggested that measures such as early waterflooding, periodic mining and acid fracturing should be properly adopted in the development process .
