Title:
METHOD FOR PERIODICALLY MEASURING TIME THICKNESS OF SEDIMENTARY STRATUM USING RECEIVER FUNCTION
Document Type and Number:
WIPO Patent Application WO/2018/107905
Kind Code:
A1
Abstract:
A method for periodically measuring the time thickness of a sedimentary stratum using a receiver function, belonging to the field of solid geophysical research. The method comprises: firstly selecting a vertical component Z, a radial component r and a tangential component t of three component seismic data, received by a seismic station, the magnitude thereof being more than four and the epicentral distance thereof being 30 degrees to 100 degrees, and selecting seismic events satisfying the condition; then respectively calculating normalized autocorrelation functions of the vertical component Z, the radial component r and the tangential component t for each of the seismic events; detecting whether each seismic event i is periodic and determining whether the periodicity of the seismic event i is a periodicity caused by a sedimentary stratum below a receiving station; and obtaining an average time thickness reflecting the thickness of the sedimentary stratum below the seismic station by using a mathematical average algorithm. The method provides a theoretical basis for the research of a sedimentary stratum.
