摘要
以东营凹陷南坡东部沙河街组四段储层的预测研究为切入点 ,针对研究对象具有分布范围广、岩性变化大、单层厚度薄、钻遇沙河街组四段油藏井的产能变化大等特点 ,利用测井资料进行了沉积相分析 ,系统地研究了南部缓坡带薄储层的沉积特点和成藏规律 ,根据不同储层的特点 ,提出了研究区储层预测方法 ,并取得显著地质效果。
We predicted and studied the reservoirs in the E s 4 of southern ramp,Dongying depression.The research objects have many properties,such as wide distribution,great lithological change,thin single layers and great well productivity change,etc.We analyzed the secdimentary facies with logs,and systematically studied the depositional properties and reservoir forming rules of the southern ramp thin reservoirs.Then we presented some description methods according to the properties of different reservoirs.These new understanding and methods are of great importance for the research and development of the hydrocarbons in this study area.
