Title:
FAR-FIELD ACOUSTIC SENSING AND IMAGING AND EVALUATION SYSTEM FOR SURVEYING OFFSHORE WIND TURBINE TOWER FOUNDATION
Document Type and Number:
WIPO Patent Application WO/2020/143187
Kind Code:
A1
Abstract:
A far-field acoustic sensing and imaging and evaluation system for surveying an offshore wind turbine tower foundation comprises a downhole tool unit (1), a data collection and transmission unit (2), an exploration ship (3) and an onshore data processing unit (4). After the downhole tool unit (1) has been placed by means of the exploration ship (3) in a borehole under test, the downhole tool unit (1) is gradually raised to perform borehole logging. The data collection and transmission unit (2) collects data generated when the downhole tool unit (1) is operating, and uploads the data to the onshore data processing unit (4) to undergo data processing. The far-field acoustic sensing and imaging and evaluation system for surveying an offshore wind turbine tower foundation is a complete and independent measurement system. The system can perform measurement of acoustic feature parameters of a stratum on which a wind turbine tower foundation is to be constructed and comprehensive evaluation of a geological structure in one operation.
