Abstract
Chang-8 oil reservoir set is one important exploration horizon in the Southwestern Ordos basin, which can be divided into Chang-81 oil reservoir set and Chang-82 oil reservoir set from top to bottom. The oil migration in Chang-81 and Chang-82 reservoir is discussed by using the analysis technique of nitrogen compounds. It turns out that Chang-81 oil reservoir set had 5 oil charging points, from which crude oil from Chang-7 oil source rock migrated in a long distance along the reservoir set, and the transport distance can reach 40～70km. Chang-82 oil reservoir possessed one oil source fault across Xi-269 well and Bai-269 well, and after the fault crude oil underwent radially lateral migration whose migration distance was up to 110km.
