砾岩在不同矿化度下的岩电参数变化规律

VARIATION REGULARITY OF CONGLOMERATE ROCK-ELECTRO PARAMETERS UNDER DIFFERENT SALINITIES

为解决地层含油饱和度计算误差的问题,用不同矿化度地层水进行了地层因素和电阻增大率的实验,发现了砾岩储层岩电参数的变化规律。进一步有效地利用这一规律可以对含油饱和度的计算误差进行校正,从而修正开发储量中的计算误差。这一规律的研究对克拉玛依砾岩油藏的开发具有重要的指导意义。

During oil production, the water injection technique is used to increase the pressure of the reservoir. The salinity of injected water is usually lower than the original water salinity of the reservoir, so the reservoir water will be placed gradually. This has to do with a variety of rock-electro parameters such as m, a, m, and b which are related to oil saturation calculation of the reservoir. In this paper, the authors arranged a series of experiments to test the characteristics of strata factors and resistance increment under different salinities, and concluded the regularity governing the variation of the conglomerate rock-electro parameters, which is of great guiding significance in the prospecting for oil in the Karamay oilfield.
