摘要
Abstract
Shahejie Formation in the Bohai Bay Basin is a key exploration target.However,there are many difficulties in the stratigraphic division of the Shahejie Formation in Well Bozhong D near the uplift belt.The accurate identification of sedimentary environments is important for predicting the distribution of high-quality reservoir in this area.Using paleontological data such as ostracods,sporopollen,and algae,com-bined with lithological and electrical logging data,the Shahejie Formation is divided into three members from bottom to top:3rd Member,2nd Member 2,and 1st Member.Based on the lithological characteristics of the study area and combined with the ecological characteristics of algae and ostracod fossils,it is considered that the Shahejie Formation in Well Bozhong D is in a lakefront-shallow lake sedimentary environment.关键词
