The control equation consist of completely coupled deformation equation, seepage equation, conduction and convection equation of heat, which describe the reservoir non - liner performance. 2, present the detailed strategy and methods to solve this mathematics model, the basic strategy as follows : regard the deformation equation ? seepage equation conduction and convection equation of heat as separate system, and solve the equation by coupling and iterative method ; disperse the control equation in the geometry field by the finite element method ( galerkin ), and in the time field by the finite difference method : programme the computer program on this task ; when the solving, take the combinative measures of the thick and thin mesh ; successfully carry out the numerical simulation in vast 3d heat extraction system of hdr
2 、提出了高溫巖體地熱開發的固、流、熱多場耦合數學模型的數值解法，其基本的求解策略是：將固體變形，流體滲流與溫度場方程看成獨立的子系統，耦合迭代求解；利用有限元離散（ galerkin ）方法將控制方程在幾何域上離散，並用差分法得到時間域上的離散方程，並在此基礎上，編制了相應的計算機源程序；有限元求解中，為減小邊界效應的影響，在計算中採取粗細網格結合的方法，順利地實現了高溫巖體地熱開發三維巨系統的數值模擬。 -
