A STUDY ON RESERVOIR DESCRIPTION METHOD AND ITS APPLICATION FOR UPPER TERTIARY IN THE WESTERN AREA OF SHANJIASI

The Upper Tertiary in western area of Shanjiashi in Dongying was deposited in the period of depression development,the overlaping or draping reservoir was formed in Guantaozu Formation,and the lenticular lithologic gas pool was formed in Minghuazhen Formation.Based on reservoir features of thin layer and small scale,many techniques including geophysical exploration were used to the study of reservoir formation and distribution,as well as pool-forming conditions.The possibility of hydrocarbon-bearing in the reservoirs was predicted.The reservoir description method for the Upper Tertiary in the area may provide some guidings for hydrocarbon exploration and development in other area.
