摘要:
在油层注水开发过程中,随着注入水与原始地层水逐渐混合,油层被水淹,由于注入水与原始地层水矿化度不同,造成混合液电阻率逐渐发生变化,相应的地层电阻率、地层电阻率增大系数、岩电参数b和n等均发生相应变化。选取朝阳沟油田10块岩样,模拟地层高温高压,开展了水驱油岩电相渗实验研究,从理论上对各储层参数的变化规律进行了探讨。研究结果为水驱地层含水饱和度模型优选及参数的正确选取提供了理论依据。根据实验结果计算的目前含水饱和度精度达到5.4%,满足注水开发中水淹层测井解释的需求。
Abstract:
Abstract: In the water flooding development, as the injected water is gradually mixed with the original formation water to flood the oil layer, the resistivity of the mixed liquid gradually changes due to the different mineralization degree of the injected water and the original formation water. Correspondingly, the formation resistivity, formation resistivity increase coefficient, and rock electrical parameters b and n all change accordingly. Ten rock samples from Chaoyanggou Oilfield were selected to conduct experimental study on the water flooding rock electrical phase infiltration undersimulated high temperature and high pressure of the formation. The variation law of each reservoir parameter was theoretically discussed. The research results provide a theoretical basis for the selection of water saturation model and the parameters. The current water saturation accuracy based on the experimental results reaches 5.4%, which meets the production requirement.
