塔中地区东南部石炭系CⅢ油层组含砾砂岩段沉积相研究
Sedimentary Facies Research on Pebbled Sandstone Zone in CⅢ Oil-bearing Formation in Carboniferous System in the Southeast of Tazhong District
摘要
Abstract
Core,logging and 3D seismic data is used for sedimentary facies research on pebbled sandstone zone in CⅢ oil-bearing formation in Carboniferous system in the southeast of Tazhong district. The results show that sedi-mentary environment for pebbled sandstone zone in the southeast of Tazhong district is tidal delta and that tideway and tidal sand bar are developed near well Tazhong 4 and well Tazhong 16. Under different sedimentary environ-ment,sedimentary faces and sand body distribution are significantly different and target of progressive exploration and development is different. Reservoir conditions are favorable in Tazhong 4 and Tazhong 16 well block,as long as effective barriers exist,large lithologic or stratigraphic hydrocarbon reservoir can be formed. Sand flat in upper flow regime near stratigraphic overlap in pebbled sandstone in Tazhong 4 and Tazhong 16 well block is the most favorable target for progressive exploration and development. Fine investigation on sedimentary facies in pebbled sandstone zone is important to the exploration of new subtle reservoirs and improvement of exploration success rate.关键词
