NEW PROGRESS IN THE STUDY OF OIL WELL DYNAMICS AND EARTHQUAKE

The relation of oil well dynamics with earthquake is studied, and some new progresses have been made.They are:the mathematical expression of the relation between the parameters of oil well dynamics is given;the calculation method and program to inverse the variation of stress in oil-bearing formation with oil well pressure are given;the evolutive images of stress field in time, space and strength are presented;the temporal and spatial characteristics in the evolution of anomalies and the tectonic location of monitoring site are studied synthetically.
