ydraulic fracturing is the pivotal technology of tight
unconventional reservoir, and accurate monitoring of
fracture morphology is related to fracturing effect evaluation,
well productivity prediction and the follow-up measures.
Compared with traditional methods, electromagnetic
monitoring can obtain the Effective Propped Volume (EPV)
that actually reflects the productivity, solve the abuse such
as low fracture identification accuracy, limited by the specific
time. This paper introduces an physical and numerical model
that uses electromagnetic characteristics to accurately
monitor the parameters of the fracture. A triaxial transmitting
- triaxial receiving instrument which is approximate to the
construction site is set up, the relationship of electromagnetic
monitoring signals and the fracture parameters is obtained.
By placing the transmission source plane perpendicular
to an appropriate coordinate axis in a three-dimensional
rectangular coordinate system the length and height of the
fracture could be monitored by the signal of the long receiver
while the transmitting source surface being perpendicular
to the Z-axis. The azimuth could be inverted according to
the magnitude of the signal peak when the transmitting
source surface is perpendicular to the X-axis. The sign of
azimuth could be determined by setting a M-axis (the Z
axis rotates counter-clockwise 45 degrees in the XZ plane).
