Oil Enrichment Regularity of Putaohua Formation in Daqingzijing Area

Due to Putaohua formation is non-essential reservoir in Daqingzijing area,less attention is paid on the basic geology research.Aim to boost the exploration development of the oil layer;a comprehensive analysis of the seismologic means,geology,logging and well testing is adopt.Meanwhile,the pointed recognition methods and forecasting techniques of different types of hydrocarbon reservoir are proposed.Finally,the horizontal and vertical distribution is concluded,and then the oil enrichment regularity of Putaohua formation is build up according to priority,which is directly used in the practical exploration of lithologic deposit in Daqingzijing area.
