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.
Ordos Basin LD area is the world-famous loess plateau area, and the seismic data processing and reservoir prediction are facing great challenges.Because of the low exploration area, exploratory wells, especially the S-wave logging are very few, has been restricting the application of prestack technology, then the Loess Plateau How to perform prestack inversion in less and less area? This paper innovatively introduced the fruit fly optimization algorithm in the field of prestack inversion, and used Schaffer function F6 to compare the performance of four algorithms to complete the one-dimensional model trial calculation. Drosophila optimization algorithm to optimize the overall advantages of the construction of virtual wells, and its introduction to the prestack simultaneous inversion, and obtain better inversion results, in order to solve the problem of prestack inversion in the Shallow Wells area of the loess plateau.
