    Abstract： In order to solve difficulties in gathering and transportation of oil and gas with low viscosity， condensation and density， high wax content， gas/oil ratio and wax precipitation point in Chang 10 reservoir of Gao 52 Well Area in Ansai Oilfield and prevent wax precipitation， researched are the rheological property of crude oil from Chang 10 reservoir and the law of temperature drop along dissolved gas crude oil pipeline， used is the experience in Chang 6 reservoir surface engineering construction of the oilfield for reference and puts forward is a 2-stage station layout mode in which priority is given to “Well Cluster→Pressurization Point→Joint Station”. Applied are the closed pressurization point oil/gas multiphase flow transportation technology， automatically pitching ball for wax removal and electromagnetic wax control techniques to solve the problem of pipeline wax precipitation and closed oil/gas transportation， good safety and environmental protection benefits have been achieved and surface engineering construction investment has been reduced， which provides technical supports for reasonable and effective development of Chang 10 reservoir in Huaqing， Jiyuan， Heshui and other oil areas in Changqing Oilfield.
