岩石压缩系数计算的新方法
NEW CALCULATING METHOD OF ROCK COMPRESSIBILITY COEFFICIENTS
摘要
Abstract
Elastic modulus has been widely applied in the calculating methods of rock compressibility coefficients.Through the practical calculation by elastic modulus, the existed error of the method is mainly shown that the calculated pore compressibility coefficient of the porous media is smaller than that of the rock matrix with non-porous media. The above result is contrary to the principle of elastic mechanics; the new expression of the pore compressibility coefficient is derived with the help of the above theory and moreover the different calculating methods of the coefficients are analyzed and compared. Meanwhile, the influences of these various methods on dynamic OOIP have been made clear. The analyses results show that the new calculations are reasonable. Moreover, the new calculating method initiates a new idea and approach for the prediction of the compressibility coefficient in petroleum reservoir rocks.关键词
