Abstract:
In this paper,the comprehensive studies are carried out on the tectonic characters of the front margin along the middle section of the Longmenshan Overthrusting Belt based onthe analysis of dynamics,kinematics and geometric deformations on the overthrusting beltwith the example from the Yazi River S...

THE DISTRIBUT1ON OF OIL BEARING FORMATION BELOW THE WATER-TOP IN THE EAST FLANK OF LAMA DIAN OILFIELD AND NORTHEAST FLANK OF SARTU OILFIELD

Xu Yunxin, Tan Baoxiang, Yang Zhongming

1994, 16(1): 43-52. doi: 10.11781/sysydz199401043

Abstract(1404) PDF-CN(406)

Abstract:
Based on the core data from 8 core hole,the water top (oil-water transitional belt)in the two oilfields is redivided.It is concluded that its thickness range reaches 36.6-68.6m more than that acquired by the data of electric loggings and oil testings.Therefore,it means the oil saturation being 30～40...

A PRELIMINARY STUDY ON THE EVOLUTION OF DOLOMITE-DIAGENESIS IN SOME FORMATIONS OF THE JIYANG DEPRESSION
