压力敏感性储层超前注水开发研究

Enserch of Advanced Water Injection Development of Effect of Pressure-Sensitive Reservoirs

压力敏感性储层在开发过程中,储层渗透率随储层压力的降低而下降,进而影响油井产量及油田开发效果。为了量化地层压力变化对压力敏感性储层开发的影响,通过实验研究得出了储层渗透率随地层压力的变化规律。进而建立了压力敏感性储层渗透率及油井产量随地层压力的变化关系,并结合油田开发实例,研究了超前注水在压力敏感性储层开发中应用效果。

Permeability drop down gradually with the decrease of reservoir pressure in the process of developing of pressure sensitive reservoir. The oil well production and development effectiveness were affected. In order to quantify the influence of variety of formation pressure. Starting from the experimental data, the relationship between permeability and reservoir pressure was obtained. The restored regularity of permeability and oil well production in process of varying of reservoir pressure were researched on combining the oilfield development practice. The effectiveness of advanced water injection in process of development of pressure sensitive reservoir were studied.
