摘要:
针对原有的底水油藏临界产量及最佳射孔程度计算公式存在的错误,依据渗流力学理论,应用平面径向渗流和半球面向心渗流组合模型,重新推导了底水油藏的临界产量及最佳射孔程度计算公式。修正后的最佳射孔程度计算公式与原公式的不同点在于:原公式只能求得数值解,而修正式可求得精确的解析解;原公式只能用数值解法求取最佳射孔程度的最大极限值,而修正式首次利用数学解析的方法,求解了底水油藏最佳射孔程度的最大极限值为1/3。利用鄂尔多斯盆地某底水油藏的实际生产数据进行计算,结果表明:临界产量修正式与原公式计算结果的相对差值随无因次泄油半径(Re/H)的减小而增大,随射孔程度的减小而增大,最大相对差值可达9.24%;最佳射孔程度修正式与原公式计算结果的差值不大,随无因次泄油半径(Re/H)的减小而增大,最大相对差值为0.96%。
Abstract:
Regarding the errors in the calculation formulas for critical oil production rate and optimal perforation degree of the original bottom water reservoirs,based on the theory of seepage mechanics,the modified formulas were derived using the combined model of plane radial flow and hemispherical core flow. An important feature of the modified formula for optimum perforation degree,which differs from the original formula,is that an accurate analytical solution can be obtained by the modified formula while only a numerical solution can be obtained by the original formula. Another feature is that the modified formula uses mathematical analysis for the first time to solve one-third of the maximum limit value of optimal perforation degree for a bottom water reservoir,while the original formula can only be used to obtain the maximum limit value of the optimal perforation degree with a numerical solution. The actual production data of a bottom-water reservoir in the Ordos Basin is used to calculate.The results show that the difference between the modified formula and the original one for critical oil production rate increases with the decrease of dimensionless drainage radius (drainage radius/formation thickness),and increases with the decrease of the perforation degree,with the maximum relative difference of 9.24%. The difference between the modified formula and the original one for optimum perforation degree is small,and it increases with the decrease of dimensionless drainage radius,with the maximum relative difference of 0.96%.
