Abstract: At Pucheng oil field, Long time exploitation and heavy corrosion of downhole casing make serious comprehensive circulation loss. Because conventional leaking identification technologies are hard to identify leaking location and leaking quantity of wells, it is necessary to explore new one. In this paper, main equipments and leaking identification explanation methods of leaking identification with flowrator are introduced. Based on actual condition of Pucheng oil field with high temperature, corresponding improving measures are proposed to improve range of applicability of well temperature of leaking identification equipments. The application of leaking identification technology with flowrator on 3182 Pu 53 block, Pucheng oil field attains satisfactory effect. Nowadays, this technology has been widely used in Pucheng oil field.

Key words: flowrator, leaking identification technology, Pucheng Oil field, application 
