| 摘 要： | 讨论了谱有限元方法在中子测井数值模拟中的应用,用球谐函数谱展开和有限元耦合方法求解Boltzmann中子输运方程,得到了这种耦合方法的收敛性。研制了三维有限元程序,实现了中子测井问题数值模拟的正演计算,实际算例表明此方法是有效的。

| Abstract: | The application of spetral finite elment method to well-logging problem is discussed.Using spherical harmonic function expansion and finite element method,Boltzmann transport equation is solved numerically,the convergence of the method is approved.A 3-D software is developed to simulate the neutron logging,and the results are satisfied. |
