Abstract

Abstract

The main aim of this paper is to analyze reflectors in the pilot hole of CCSD (China Continental Scientific Drilling). The lithology of the metamorphite in the CCSD pilot hole can be identified by logging curves and geo-logging data. The wave impedance can be calculated by using acoustic (AC) and density log (DEN) curves. By comparing the acoustic wave impedance with the VSP (vertical seismic profile), the reflectors of the CCSD pilot hole have been analyzed. The results indicate that reflected waves are primarily produced by the wave impedance properties of the lithology (such as the wave impedance difference between eclogite and paragneiss or between eclogite and ultrabasic serpentinite, etc) and the fracture. The fractures are mainly the ductile shear zones. If the fracture thickness is less than 1m, reflectors cannot be produced. The study provides significant data concerning the interpretation of seismic reflection signals in the earth's crust.
