Study on Stratigrafic Division and Correlation of Formation Yingcheng-Shahezi of Lishu Rift

Abstract:

Stratigrafic division and correlation are the basis study on sedimentation and reservoir. Guided by the theory of sedimentology,using drilling,logging,sesmic and other data,with the integrated application of various methods,124 wells which drilled in formation Yingcheng-Shahezi of Lishu rift were carried out classification and correlation,which have shown that formation Shahezi overlapped from sag to high positon,and formation Yingcheng suffered severe erosion later. Three regional marker beds can be identified,formation Yingcheng and Shahezi can be divided into four sand groups. Sangshutai sag was the deep depression of each sand group,Qinjiatun,Sujiatun and Shuanglong area were sub-sags,sedimentary center steadily developed.
