摘　　要：渤海油田部分开采区域为了研究油田水驱效果、水淹规律、小层剩余油分布状况等地层流体最真实情况,通过研究决定在渤海油田部分开发调整井,优选合适的取心钻头、密闭液等进行开发调整井密闭取心作业。近年来该项密闭取心技术在渤海油田开发调整井中得到推广和应用,对于渤海油田开发调整井开展不同油层水淹程度与剩余油分布情况的研究,优化开采方案,进一步识别区域岩性组合特征,提高油田的采收率及原油产量起到了重要作用。In order to study the true situation of formation fluids in some development areas, such as water displacement efficiency, the water-flood layer regularity and the remaining oil distribution in thin single layers, the matched core-bit and sealing liquid were selected by Bohai Oilfield to carry out the sealing core drilling operation. The successful application of this technology in recent years has played an important rule in the research of water-flooding degree ＆ remaining oil distribution in different oil layers, the optimization of subsequent production schemes, the identification of regional lithological association and the improvement of oil recovery and crude oil production in the development ＆ adjustment wells in Bohai Oilfield.
