The method for parameter selection of artificial earthquake stimulation is presented in thi.

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.

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.

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.

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.
