The method for parameter selection of artificial earthquake stimulation is presented in thi.
简要介绍了人工地震增油的机理。
As a new technique for tertiary oil recovery or EOR,artificial earthquake stimulation is increasingly valued for its quick response,high efficiency,non-pollution to well and influence-free on regular production of oilfield.
人工地震增油技术作为三次采油的新技术,以其见效快、效率高、不污染油井、不影响油田正常生产等优点而受到日益广泛的重视。
Compared with earthquake data,artificial earthquake profiling data have a lot of advantages,such as that source is spherically symmetrical and their position is known;observational points are very dense;sources and observing points are in a straight line;and the velocity structure of the studied area can be determined exactly.
同天然地震资料相比 ,人工地震剖面观测资料具有震源球对称且位置已知 ,观测点位密集、震源和观测点呈直线排列、速度结构已知等突出优点。
A vibration experiment on isolation table with laminated steel rubber bearing was done using manual seismic, and the motion acceleration data in time history of isolation table were observed in three directions with strong motion earthquake instruments.
通过人工制震对带有钢板叠层橡胶减震垫的减振台进行振动实验研究 ,用强震观测仪在 3个方向上测得其振动加速度时程值 ;用D’Alembert理论建立了 1质点计算模型 ,从而计算出带有钢板叠层橡胶减震垫减振台的各个特征参数 ,即减振台在 3个方向上的临界阻尼比和刚度 ,为进一步研究减振台的非线性振动及减震垫的减震性能提供了依据·对参数计算结果进行分析 ,减振台双柱在水平两个方向上刚度的大小 ,并不是其尺寸比的 4倍 ,原因与柱下剪力墙的刚度也折算到柱的刚度中有关 ,故实际测试结果与理论计算的结果并不矛盾
Based on collecting and analyzing of the data such as the geophysical prospecting,geology,satellite remote sensing and so on,as well as the geologic survey,man-made earthquake exploration for deep and shallow layers and Hg-gas observing are carried out,the position,mode of occurrence and activity of Laoyachen fault have been investigated.
通过对物探、地质和卫星遥感等资料的收集解释分析 ,以及开展地质、深浅层人工地震勘探和汞气测量 ,查清了该断层的位置、产状和活动性 ,为该市的地震小区划工作提供了重要依据。
In this paper,the author gives an account of the H_∞ optimization theory,which has just risen in the world recently,and its application to earthquake prediction, man-made earthquakes and other fields;points out the merits and demerits of the H_∞ optimization theory.
本文介绍了近期在国际上刚刚兴起的 H_∞优化理论及其在地震预报、人工地震和其他方面的一些应用,指出了 H_∞优化理论的优缺点。
