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

摘要: 东营单家寺西部上第三系为盆地坳陷期的充填沉积,在馆陶组地层形成了超覆或披覆型油藏,在明化镇组形成透镜体状岩性气藏.针对该区储层薄、规模小的特点,应用物探等多种技术手段,研究了该区储层的成因、空间展布及成藏条件,进行了储层及其含油气性预测.探讨了适合本区上第三系油气藏特点的描述方法,以求对其它地区的油气勘探与开发给予指导.Abstract: 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.
