摘要
在分析钻井泥浆滤液渗流特征的基础上,根据泥浆滤液的渗流方程,构建了表征储层渗流特性的参数计算模型,通过统计分析实际的试油结果与所提取的渗流特征参数,建立了根据储层渗流特征参数计算产能指数的储层产能预测模型。渗流特征参数与储层微观孔喉结构参数对比表明,渗流特征参数值能够很好地反映储层的微观渗流特性。库车地区阵列感应测井计算产能指数与实际试油结果的平均误差为0.098m3/(d.MPa.m),表明了该方法的有效性,能够为测试前的储层产能预测提供可靠的依据。
Parameter calculation model characterizing seepage characteristicsof reservoir was established based on the percolation formula of mud filtrate and the analysis on the seepage characteristics of the mud filtrate.Forecasting model of reservoir productivity was built according to the seepage characteristic parameters after the statistical analysis on the actual well testing result and the calculateddata.The correlation of the seepage characteristic parametersand microscopic pore-throat structure parameters sh...
