Guangdong Pearl River Delta oil pipeline project is the Guangdong Provincial Government and China Petrochemical Corporation’s key construction projects, only through the Guangzhou Panyu Lot 80km, according to incomplete statistics, respectively, across the river, reservoirs, villages, etc. to be taken horizontal orientation Drill through the lot there are more than 50, the general depth of 4 ~ 12m, the largest of more than 20 meters. This paper describes the application of measurement, geophysical and computer technologies. The GPS RTK method is introduced in detail, and two (single and three) deep buried close-spaced pipelines are enumerated.
