摘　　要：鄂尔多斯盆地LD地区是举世闻名的黄土塬区,地震资料处理和储层预测面临极大挑战.而且由于工区勘探程度低,探井尤其横波测井非常少,一直制约叠前技术的应用,那么黄土塬少并区要如何进行叠前反演?本文创新性地在叠前反演领域引入果蝇优化算法,并利用Schaffer函数F6进行四种算法性能比较测试,完成一维模型试算.利用全新的果蝇优化算法全局寻优优势构建虚拟井,并将其引入到叠前同时反演中,取得较好反演效果,以期解决黄土塬少井区叠前反演问题.LD area of Erdos Basin is famous for loess Plateau. So seismic data processing and reservoir prediction face a great challenge. And this area is low degree of exploration with few wells. Especially shear wave logging is very little. So it has restricted the application of prestack technology. So how to carry out prestack inversion in the loess Plateau？ This paper innovatively introduces the fruit fly optimization algorithm to prestack inversion, and tests the performance of the proposed algorithm by the use of Schaffer function F6, and finishes the Comparison of the results of sloving Schaffer function F6 by four algorithm, and the one-dimensional model is trial. Then we take advantage of new fruit fly optimization algorithm global optimization to build virtual Wells, and introduce into prestack inversion, obtain good inversion result. in order to solve the loess tableland less wellblock prestack inversion problem. Finally we hope this method can solve the prestack inversion problem in the less well area of loess Plateau.
