Abstract(751) PDF-CN(323)

Abstract:
The illite content in the mixed layer can be obtained by systematic micro-area component analysis of M-I (montmorillonite-illite) mixed layer minerals in claystone using SEM/EDAX in stead of x-ray diffraction. According to the study on the mixed layer clay minerals in a certain well, the diagenetic ...

Abstract(736) PDF-CN(410)

Abstract:
In accordance with the parameters selected systematically from the drilling wells and the data from regional geological surveys on the border areas of Sichuan Basin, the integrated geological and geophysical interpretations for a new completed seismic profile in the basin are carried out. Thereafter...

GEOLOGICAL INTERPRETATION AND THE CHARAC-TERISTICS OF TECTONIC EVOLUTION ON REGIONAL SEISMIC PROFILE IN NORTH CHINA BASIN

Abstract(692) PDF-CN(279)

Abstract:
North China Basin attributed to a type of cratonic basin from Sinian to Triassic time is superimposed by Meso-Cenozoic converted faultdown basins. The characteristics of seismic waves can be grouped into three regional datum waves, six reflective waves of local or erosion surfaces with four tectonic...

METHOD OF “RECOVER LAYER BY LAYER” FOR CALCULATING THE PALEOTHICKNESS OF SEDIMENTARY LAYER

Yuan Bingcun, Qian Yizhong
