国家海洋局第一海洋研究所科技人员以重心法为主的GP~5计算机软件成功地将面积仅几十平方公里内的80多口油井的油种进行分类,准确地鉴别了这些类型的油种,并同时与邻近各油区的油种区别开,这是一种以油井力单位的油种鉴别新方法,并已为胜利油田埕岛油田油井原油‘指纹’图谱建立 The GP-5 computer software, which is based on the center of gravity method, was successfully classified by the scientists and technicians of the First Institute of Oceanography of the State Oceanic Administration to classify the oilseeds of more than 80 oil wells in an area of ​​only several tens square kilometers and accurately identify these types of oil Species, and at the same time, it is distinguished from the oil species in adjacent oil fields. This is a new method for identifying oil species in oil well unit and has established the ’fingerprinting’ pattern of oil well in Chengdao Oilfield of Shengli Oilfield
