阿姆河右岸生物礁滩储层的横波速度预测方法
S-wave velocity estimation of biological shoal reservoir on right bank of Amudarya
摘要
Abstract
In order to improve the pre-stack elastic inverse accuracy and reliability in the biological reef reservoir from the Amudarya right bank,this paper discusses a method for S-wave velocity estimation in this reservoir.The method uses the relation between P-wave velocity and S-wave velocity to estimate the S-wave velocity from the small porosity reservoir.The relation is obtained from the petro-physics test and analysis.Then,the S-wave velocity from the medium and large porosity reservoir is calculated by the methods based on the equivalent bulk modulus inversion of the matrix mineral,the pore structure inversion of carbonate rocks and the Xu-White model.Compared with the other methods to calculate S-wave velocity without considering the pore structure of this area,this method for the calculation of the shear wave velocity is more accuracy,and the result is in accordance with the S-wave velocity from the actual logging data.According to the characteristics of the biological reef reservoir from the Amudarya right bank and by using different shear velocity prediction methods to classify the reservoir pore structure are more suitable for the inversion of the biological reef reservoir and the prediction of oil and gas in this area.关键词
