Abstract:

The Vector Scanning (VS) for microseismic consists of data acquisition, data processing, and interpretation, where the last one is discussed in this paper. The interpretation studies and determines the 4D distribution of microseismic, the relationship between the microseismic and interpretation target, and the target characteristic in time and space. This paper is the 5th sections in our series articles of VS, which include the development of microseismic monitoring, and the principle, data acquisition, data processing of VS. Similarly to the other steps in applying VS, the interpretation requires not only microseismology, but also geology, petroleum and coal engineering, mechanics, and statistics, etc. The necessary condition of applying VS is to achieve the random records with relatively smaller amplitudes and without such undesired signals out of the target. Due to the discontinuous feature of microseismic both in time and space, however,even though the conditions are satisfied within the previous steps, we have to discuss some problems and determine some principles in our interpretation: (1) the reliability of the scanning output data themselves; (2) The characteristics of periodic records and remains of interference from the background noise; and (3) The 4D distribution of microseismic and interpreted target, including their geometric parameters and possibly multiple solutions.
