摘要
在对目前的商业化软件黑油模拟器中求解非对称线性系统的现行方法ＲＳＶＰ进行研究的基础上，提出了一种解实际油藏问题的新的预处理器ＲＳ一ＭＩＬＵＮ，由此得出了一种新解法ＲＳＰＣＧ，并将该方法在原商业软件中应用。应用结果表明，新解法比原解法少用一定的内存，且对于较大规模实际油藏模拟问题的单个未知量系统，求解效率可提高３０％～４０％，而对于多未知量系统，效率的提高幅度会更大。
A new preconditioned Rs/MILU and algorthm RSPCG for actual reservoir problemare proposed in this paper,It is performed on the black-oil simulator by studying the popularmethod RSVP which is used recently in commercial software for solving non-symmetric sys-tem arising from reservoir simulation. Numerical experiments demonstrate that new algo-rithm take less storage than former one and that 30-40 percent computer time is saved forsingle unknown systems from large scale reservoir simulation and much more for multi-un-known systems using new algorithm.
