简介:高分辨率3D非线性的综合倒置方法基于非线性的理论。在层控制下面,从几口井的日志数据(或所有井)在学习区域和地震踪迹,邻近井的数据是到有多重输入和产量的一个网络的输入并且综合地被训练获得全部学习区域的一个适应重量函数。综合非线性的印射关系被水库的侧面、垂直的地质的变化造并且更新。因此,倒置过程和它的倒置结果能被抑制并且控制并且有有速度倒置,阻抗倒置,和密度倒置节的高分辨率的稳定的地震倒置节,能被获得。好地质的效果在模型计算测试并且真实数据处理被获得了,它证实这个方法让高精确,好实物,和罐头被用于量的水库分析。

简介:这研究的目的是表明杆菌SP3的基本特征并且在不同原油上评估它的效果。紧张SP3是在华东从Shengli油田的一座水库被孤立的能动的、克积极的、生产孢子的杆。紧张SP3的Thecells在5.5-8.5的氢指数范围在高温度成长了直到58℃。grewfacultatively拉紧SP3并且能使用不同器官的底层,并且生产一些代谢物如此的as4-hydroxy-4-methyl-2-pentanone,methyl-2-nitrogen苯并且1,2-benzenedicarboxylic酸bisest嗯。实验室研究证明了紧张变换了并且降级不同部件并且变化物理并且原油的化学性质。紧张SP3降级了原油和原油上的细菌的生长导致了芳香的烃,树脂和沥青质的损失。原油的简历变换将在更轻的烃和全面再分配导致丰富浸透烃。有原油的微生物的相互作用是可变的,取决于微生物引起的种类和原油的化学成分。

简介:为波浪领域推测的一个精确、宽角度的单程的增殖者面对大、快速的速度变化是为关于波浪方程prestack深度移植的研究的一个重要话题。基于在这篇论文介绍的最佳的可分离的近似,有前面、反的Fourier变换的混合的域算法被用来构造3D单程的波浪领域推测操作员。这个操作员在波浪号码和空间领域分开变量。当为侧面的速度变化的时间延期在空间领域被改正时,阶段移动操作在波浪数字领域被实现。单程的波浪操作符的推动回答证明数字计算与为每速度的理论值一致,表明与最佳的可分离的近似构造的操作符能被用于为小步的盒子的侧面的速度变化。SEG/EAGE模型和领域数据的成像结果显示新方法能习惯于图象建筑群结构。
