Title:
ELECTROSEISMIC INTEGRATED MONITORING METHOD AND SYSTEM BASED ON ELECTROSTRICTIVE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/040535
Kind Code:
A1
Abstract:
An electroseismic integrated monitoring method and system based on an electrostrictive material. The monitoring method comprises: sending a current signal (S402), wherein the current signal comprises at least one of the following: a multi-frequency current signal and a single-frequency current signal, the frequency of the current signal is determined according to a proppant, and the proppant performs telescopic vibration under excitation of the current signal at a predetermined frequency; obtaining an acoustic wave signal received by means of a seismic sensor (S404), wherein the acoustic wave signal is an acoustic wave signal generated for the current signal to excite the proppant to perform telescopic vibration; and determining a vibration position of the proppant at a fracturing layer according to the acoustic wave signal (S406), wherein the vibration position is used to determine a basis for propped fracture characteristics. The electrostrictive material is used as the proppant, so that the position of the proppant can be monitored by means of microseism, and the problem that in the existing hydraulic fracturing monitoring technology, the monitoring difficulty for the proppant is large is solved.
